Your Hair or Your Hormones

Be nice to have Superman's hair…but at what price? (Courtesy; MovieBlog.com)

It’s the perfect drug for 40 million men in America who are going bald. Take it once a day to keep the hair on your head and shrink the prostate, which also commonly bothers men as they age. It’s a pill that has been used by at least 2 million reproductive age men over the last decade. But is it too good to be true?

The Best Hair Pill Yet

This magic pill is finasteride (trade names; Propecia, Proscar, Avodart). It represents a class of drug called the 5-alpha reductase inhibitors. These pills act as enzyme blockers: they prevent the male hormone testosterone from converting to its metabolite dihydrotestosterone (DHT). Although testosterone is responsible for a lot of our “male” features, DHT is more potent than testosterone for scalp hair and our internal reproductive organs (prostate, seminal vesicle). These drugs work by lowering DHT production and protect the gloriously youthful hair on our heads and the enviable ability to write your name in the snow while urinating.

And these drugs work well. More effective than topical or “rub in” medications, finasteride is great for what’s called “male pattern” hair loss which is due to a receding hairline or balding on the top of the head. In essence, it slows the growth phase of hair in these areas. However, it doesn’t treat hair loss on the sides or temple area.

Finasteride, Sex and Male Fertility

Although it may keep you looking like Clark Kent, many male infertility specialists, including myself, have concerns about finasteride. First, there is a 10% chance of sexual side effects that include erectile and ejaculatory dysfunction and lowering of sex drive. These issues can be subtle while on the pill but become very obvious when men stop it; many of my patients have noted a sexual “curtain being lifted” or “coming alive” after discontinuing the pill.

Second, there is an even more profound concern about finasteride among specialists: male infertility. Before it received FDA approval, the drug trials showed that it lowered ejaculate volume but did not change sperm count or motility on semen analysis testing (actual human fertility studies are not routinely required by the FDA). Now that it has been on the market for 10 years, though, impressive declines in semen quality have been observed and published with finasteride by many of us. This effect is not subtle either, as patients with complete sterility (azoospermia) have had recovery of their sperm counts after stopping finasteride!

There are several clues that this effect on fertility was possible. The rabbit studies done for FDA approval of the drug actually showed this effect. At 3 months, there was no effect on rabbit fertility. But, when followed longer, rabbits showed significant decreases in natural fertility. In addition, while I was writing a recent reproductive physiology chapter for Campbell-Walsh Urology, our leading urology textbook, I researched at what levels the 5-alpha reductase enzyme is found in the human testis and epididymis. Lo and behold, there are gobs of this enzyme in these important organs for sperm production and maturation, implying that the blocking agent finasteride would have an effect. So now what do we do?

At this point, controlled clinical trials are needed to prove this effect on fertility. For the time being, current thinking is that finasteride may not dramatically change sperm production in healthy men, but can impair semen quality in infertile men. Typically, the effects of medications on male infertility are reversible. So, to be proactive men should consider stopping the pill at least 6 months prior to trying to conceive. And, have confidence that she loves you just as much for other reasons. As Telly Savalas once said: “We’re all born bald, baby!”

Rise of the Instant Family

Paul Turek, MD — Mon, 09 Jan 2012 16:00:47 +0000

IVF: The elephant in the nursery room

Using sex to conceive, the chance of having twins or higher multiple births is about 1-2%. With assisted reproduction, including intrauterine insemination (IUI) in the office and in vitro fertilization (IVF) in the lab, the chance of twins, triplets or high order births ranges from 30-50%. That’s quite a big difference!

Twins have fascinated us for eons. They run in families but a twin gene has not been found. More twin babies grow up to be left handed than you’d expect, and identical twins built of the exact same genetic blueprint have similar brain wave patterns and may think the same, but have different fingerprints.

Since records have been kept starting in 1915, our multiple birth rate has been stable at 1-2% throughout most of the last century. IVF arrived in 1978 and is now 33 years old and is now performed over 120,000 times annually. One would expect it to affect our birth rate numbers at some point. Well, the data is in and it has.

The Instant Family

The Centers for Disease Control and Prevention (i.e., CDC) just published the information on twin births over the last 3 decades (1980-2009). Here are the key findings:

The twin birth rate rose 76% over this time, from 19/1000 births to 33/1000 births.
In 2009, 1/30 U.S. births was a twin compared to 1/53 babies 30 years ago. Among multiple births reported in 2009, 96% were twins.
Twin birth rates increased by 100% in women ages 35-39 years and by over 200% in women ages 40 years and older.
If the twinning rate had not changed, almost 1 million fewer babies would have been born over the last 30 years.

Since only about 1/3 of the rising twin rate can be ascribed to older moms in the study, this leaves the rise of IVF and fertility treatments as the only elephant left in the room.

An Epidemic of Multiples

Although convenient for many couples as the entire family is complete with a single birth event, the twinning epidemic has other implications. Here are some of them that concern the CDC:

Higher risk to moms health (eclampsia, gestational diabetes)
Higher rate of premature births
Less healthy, smaller sized babies (about half of twins)

When I see those twin strollers while walking down the street, I think “chock it up to technology changing the face of humanity yet again.” For the couple pushing those strollers, you will never seen bigger, or more tired, smiles. In the words of Josh Billings: “There are two things in life for which we are never truly prepared: twins.” But there is something to be said for getting the family built in one fell swoop.

The Wall of Holiday Cards

The Turek Clinic Team and the wall of holiday cards

I always tell grateful patients that the kindest thing that they can do for me is to send a holiday picture of the family. We have a wall in the clinic that is dedicated to this once a year event.

Well, you have outdone yourselves this year! The wall is full of cards and The Turek Clinic Team loves it. We received cards with photos of little kids, bigger kids, ultrasound photos of kids yet to be, dreams of kids and much more. Each telling their own story. What a way to fuel the fire of desire to continue to do what we can to help build families all over the world. Magical. So, thanks and

Have A GREAT Holiday!

Recipe for Making a Walrus

Paul Turek, MD — Mon, 12 Dec 2011 16:00:06 +0000

Being kissed by a grateful, one ton walrus…

How do you help a 2700 lb Walrus conceive? Very carefully. In fact, only a handful of walruses have conceived in captivity over the last century. In the U.S., it is 10 to be exact. But Holley Muraco, a zoologist at Six Flags Discovery Kingdom in Vallejo, has changed all that.

Now a Published Recipe

Holley’s recipe for helping captive walruses to conceive will be published in a major scientific journal, and I am proud to have had a part in this.

Posted here about a year ago, Holley watched the mating patterns and hormonal levels of walruses over 7 years. She cleverly figured out that the male walruses in U.S. zoos, among the few species that breed seasonally, are not fertile at the same time that the female walruses are fertile. She attributed it to a breakdown in the normal breeding signals that are intricately tied to day-night rhythms in the arctic. California is simply not the same as the North Pole, where these animals have evolved over thousands of years. Right next door to Santa. In essence, when it comes to fertility, captive walruses are like ships passing in the night.

The Critical Observation

Nobody in history had observed walrus mating patterns like Holley has done. It’s no surprise either because walruses live in the arctic cold and breed underwater in bone chillingly cold seas. Her observations led her to a great idea: to hormonally shift the male walrus so that he achieves his peak fertility window exactly when the female walrus is fertile (which is once a year). Holley asked me for advice about drugs, doses and timing based on my experience with human male infertility. Ended up working splendidly with a walrus conception achieved naturally, without the fancy help of assisted reproduction!

The Outcome

From these early efforts, the pup that was expected this past May made it to full term, but was stillborn. It took several days for the unbelieving mother to give up the pup–an incredibly sad time. But, now it is possible for her to get pregnant again, as several other captive walruses around the country already are, after following the new recipe. This reminds me of how truly privileged I am because I have the opportunity to help couples conceive every day by helping nature do what it does best.

Six Flags discovery kingdom Biologists Successful in Helping Walrus Conceive

Scientific breakthroughs beneficial in better understanding of walrus reproduction

VALLEJO, Calif. – January 19, 2012 – After several years of research, Six Flags Discovery Kingdom recently reached a scientific breakthrough with the conception of one of its Pacific walruses. In the last 80 years only 11 calves have been born in U.S. facilities. The results of the park’s groundbreaking efforts, lead by marine mammal reproductive specialist Holley Muraco, have now been published in the Journal of Andrology.

In this study, the breakthrough formula for walrus conception is revealed. By watching the mating patterns and hormonal levels of walruses over a seven-year period, it was determined that male walruses, one of the few species that breed seasonally, were not fertile at the same time as the female walruses.

The team was comprised of Muraco, Discovery Kingdom marine mammal trainers and staff veterinarians with fertility expertise provided by Dr. Paul Turek, a men’s health and infertility specialist, founder of The Turek Clinic in San Francisco and co-author of the study.

“We simply moved his fertile window to coincide with her fertile window, and let the usual magic happen,” said Muraco.

With Turek’s help, the Six Flags team hormonally shifted the male walrus’s fertile window to coincide with the females.

“When Holley asked me to help with the hormonal approach to moving the male walrus fertile window from spring to fall, I thought ‘let’s try what works with infertile men’ and sure enough, it worked,” said Dr. Turek.

What came to light was that the mating signals of walruses are crossed because their day-night circadian rhythms are different in captivity than in the wild.

“In essence, when it comes to fertility, captive walruses are like ships passing in the night,” said Muraco. “Reproduction in walruses is seasonal and is tied to light-dark cycles. Those cycles aren’t the same in California as they are in the Arctic.”

One reason this important observation took some time to figure out is because walruses live in the Arctic cold and breed underwater in bone-chillingly cold waters where few scientists have dared to go. Therefore, due to this inaccessibility, little is known of the walrus reproduction in the wild.

Additionally, it appears that the method used is generalizable to walruses in other facilities, as the Six Flags team has since helped walruses in other parks to conceive as well. The findings have proven significant; today, there are only 17 walruses in North American facilities, three of viable breeding age that reside in the Six Flags park.

“It’s a great feeling when we are able to improve the fertility of other species through natural methods,” said Dr. Turek, “as this is what we try to do in our clinics as much as we can.”

Wi-Fi, Sperm Counts and Fertility

Paul Turek, MD — Mon, 05 Dec 2011 16:00:03 +0000

Does the radiation danger icon apply to Wi-Fi?

Maybe it’s time to rename the “laptop” computer something else and keep if off our laps (how about mobile computers or “mobees”?). First we hear that they generate heat that elevates scrotal temperature, and now the Wi-Fi radiation itself may be a problem.

The Effect of Wi-Fi on Sperm

The Wi-Fi issue was published last week and has my patients all worked up. In this Argentinean study, researchers placed one half of the semen samples from 29 healthy men under a laptop connected to the Internet via Wi-Fi. They put the other half far away from a Wi-Fi equipped computer. A better control group would have been to keep the control sperm under the computer like the exposed sperm but with the computer turned on but disconnected to Wi-Fi. The temperature of the sperm dishes was kept constant, so any effect would not be thermal in nature. After four hours, 25% of the sperm exposed to Wi-Fi stopped moving forward, and 9% showed DNA damage. In contrast, only 14% of the sperm placed some distance from the Wi-Fi equipped computer stopped moving forward and 3% showed DNA damage.

Importantly, the proportion of sperm that was dead was exactly the same in each case, so the exposure did not actually kill the sperm. The biggest difference they found was that sperm exposed to Wi-Fi lost the ability to move forward purposefully. It would have been a better study if these sperm were then followed for 4 more hours without exposure to Wi-Fi to see if there was a recovery of motility. The authors “speculated” that Wi-Fi could affect male fertility.

An Alternate View of Wi-Fi and Sperm

Does this bench top test accurately reflect real life biology? Hardly. Is this the natural environment of sperm, bare-naked in a half ounce of fluid spilled onto a computer with Wi-Fi all around? No, but I guess it depends what kinds of websites the computer’s owner is perusing and what kind of personal activity that it generates. So, it’s really impossible to infer that a man using a laptop with Wi-Fi on his lap for more than four hours will be less fertile.

A lesson in electromagnetic fields (EMFs) might better convince you of this belief. The strength of Wi-Fi (wireless fidelity) and W-LAN (wireless local area network) electromagnetic fields is considered weak. Although Wi-Fi moves data quickly, it emits very weak signals that do not travel very far. Typically only 30 to 200 mW of power is emitted from Wi-Fi devices. For a comparison, below is a list of power levels associated with devises that we normally hold near our heads:

Blue tooth headset 100 mW
Cell phone 200-600 mW
CB radio 4000 mW

In addition, Wi-Fi operates at far lower power densities (2.4 to 5 GHz) than cell phones (900MHz to 1.9 GHz). Lastly, the power density, and therefore any effect, from Wi-Fi (as with any other form of energy) rapidly decreases with distance away from the Wi-Fi antenna, following the “inverse-square law.” Thus overall, the exposure from Wi-Fi is 10-fold less than cell phone exposure, as one normally does not hold the Wi-Fi antennae that close to the body – as is done with cell phones.

So if you want to, worry about cell phones and blue tooth headsets rather than Wi-Fi networks in terms of exposure and health. Honestly, there is no real evidence yet that exposure to radio signals from Wi-Fi adversely affects any health issue in the general population. Maybe if we wore computers like hats or kept them in our underwear we might be at risk…maybe. For now, put a pillow between your privates and your laptop.

Why is Awake the New Sleep?

Paul Turek, MD — Mon, 28 Nov 2011 16:00:01 +0000

Sleeping Beauty definitely gets enough sleep (Source: Disney)

It was no surprise to me to read a recent study that showed that when Stanford men’s basketball players got more than 10 hours of sleep nightly, their on-court performance improved dramatically. They ran faster sprints, took more accurate shots and were less fatigued. Another example of more sleep translating into improved awake performance.

Facts About Sleep Deprivation

According to a recent national survey and the American Academy of Sleep Medicine, here are the current facts about sleep:

Adults should get 7-9 hours of sleep nightly.
Short sleep is defined as less than 6 hours of sleep.
Almost half (48%) of Americans say that they are not great sleepers.
More than 35% of Americans get less than 7 hours of sleep.
On average, “good” sleepers get 1-hour more sleep every night than poor sleepers.
13% say that they never get a good night’s sleep.
1 in 20 Americans have fallen asleep at the wheel while driving in the past month.
1 in 5 Americans have sex less often or have lost interest in sex because they are too sleepy.
In general, we sleep one hour less every night with each passing generation.

Sleep as Oxygen

During sleep, body temperature falls, muscles relax, the heart beats more slowly, blood pressure and pulse rate fall, and breathing slows. Clearly, sleep is more than simply rest and relaxation. It is a time of growth, recuperation and repair. Losing sleep may not physically kill you like being oxygen-deprived, but short sleep patterns are linked to depression, obesity, heart disease, loss of sex drive, attention disorders and a higher likelihood of developing a work-related disability. One Swedish study even showed that sleep deprived people look tired and less healthy and therefore less attractive to others.

Not only that, it’s not that easy to bounce back after losing sleep. The impairments caused by sleep-deprivation remain even after sleeping in for a day. Full recovery after sleep deprivation may take several nights of extended sleep.

So why does our society applaud those who stay up working all night rather than sleeping? Sleep deprivation is no badge of honor; it’s a threat to your health. Maybe this is why the Guinness Book of World Records refuses to recognize any record claims for lack of slumber. In my view, sleep ranks up there with nutrition and exercise as important pillars for a healthy, long and fulfilling life.

Are Fathers Better Citizens?

Paul Turek, MD — Mon, 21 Nov 2011 16:00:01 +0000

What wouldn't you give to help one of these? (Source: Leonardo Da Vinci, 1468)

As a surfer, I remember charging pretty big walls of cold, wintery Northern California water with the goal of getting a fast, albeit short, adrenaline-stoked ride. Years ago on Thanksgiving, I was pummeled by a big swell to the point that I wondered whether I would make it out of the water alive. But once I married and had kids, the risk element of waves larger than a single story high became less attractive to me. It wasn’t worth it. Too much at stake. Does fatherhood also reduce other types of risky behavior?

Fatherhood is Transforming

It apparently does. It is well known that fatherhood can be “transformative” or “tempering” for men. But what shape that transformation takes has not been studied very much, despite the fact that unattached men are considered by some to be a source of society’s ““suffering” or “instability.” Loose cannons so to speak.

Fatherhood and High Risk Behavior

A newly published study has tackled this issue. It addressed the changing patterns of crime and substance abuse in new fathers, as these behaviors can threaten both health and society. Specifically, the study asked whether men are less likely to drink, use tobacco or commit crimes after they become fathers. In other words, do tough guys straighten out after having kids?

The authors followed over 200 men ages 12 to 31 who demonstrated high rates of juvenile delinquency in a metropolitan area. They were assessed annually for self-reported acts of crime and court records were reviewed for arrests. Self-reported rates of beer, wine, hard liquor, tobacco and marijuana use were documented, as were co-habitation, marital status and age at first fatherhood. And remarkably, this study was conducted over 19 years!

It has been previous shown that marriage itself and getting older can reduce men’s negative behavior, but this study clearly demonstrated a real association between fatherhood by itself and reduced crime and substance abuse patterns. And, the effects were large and long lasting. Of note, these changes were greater amongst the older men in the group (late 20’s and 30s) and were distinct from those changes expected as men age. Lastly, unlike marriage, cohabitation alone was not shown to reduce risky behavior in young men.

A Golden Opportunity to Help Men Help Themselves

Why is this important? One reason is because it suggests that first fatherhood may present a real opportunity to improve the health and behavior of young men. God knows that there are not many opportunities to do this with those who consider themselves otherwise immortal. New fathers might be more willing to hear messages and make life style changes when they are holding what might be their noblest work in their arms. And these changes in behavior could affect the health of the individual, his children and his family. After all, and I am not sure who said this, “A baby will make love stronger, days shorter, nights longer, bankroll smaller, home happier, clothes shabbier, the past forgotten, and the future worth living for.”

Guide to Surviving the Holiday Season

Paul Turek, MD — Mon, 14 Nov 2011 16:00:30 +0000

Cleaning a set of these every week is one way to "busy your hands."

Two patients told me that they were getting divorced this week. They came to the office and thanked me for all that I have done for them. They wished that the assisted reproductive technology had worked and given them children, but it didn’t. The relationships simply couldn’t tolerate the strain and gave way. Unfortunately this is not uncommon.

The Stress of Infertility

Don’t doubt for a minute that being infertile doesn’t have the same impact as having cancer. Very little can tear holes in the fabric of a relationship like infertility can. Add to this the romance of the holiday season and you have a recipe for potential disaster. Gathered families encircled by the howling laughter of children; smartly dressed kids at parties just learning to be polite; parents reveling in the enchantment written on the faces of children hearing holiday stories. To the infertile, its like having walking pneumonia—it just never seems to get better or go away.

Eight Ways to Reduce Your Holiday Stress

Maybe it’s not that bad. Maybe the holiday season is just more stressful. What can you do about it? Here are some tips for men as the holidays approach:

Take smaller steps. Stress and depression are like the flu: give them some time to run their course and pass through. You will make it, and you will be stronger because of it.
Make a plan. Spinning out of control without a plan for the problem can cause great anxiety. Simply agreeing to take the next month off and start again in the New Year can make all the difference in the world.
Enjoy each other. After all, you have found a soul mate that is going through the same experience. Give and get that big hug that can make all the difference in the world
Express yourself. Cry on her shoulder and not in a closet. Vent about that wicked day by journaling. A belly laugh or a primal scream is even better. Empathy is a very rich and particularly human experience with immense healing power.
Relieve your stress. Exercise, yoga, massage and acupuncture are fabulous ways for men to “vent” and relax. There is something about those endorphins that waft through the body after a long run…
Be mindful. Take your eyes off the Ipad and lose circular thoughts that lead to nowhere. Take note of the present. Quietly observe life. Breathe to relax. You are an organism, not a machine.
Try fasting. From emails, texts, news, stock quotes. Do you really think that you can keep up with the web growing at a rate of 7.3 million pages per day?
Busy your hands. There is enormous therapy to be found by working with your hands. In the words of Michael Crawford, author of Shop Class as Soulcraft: “Fixing things feels good.”

Fertility from Sterility

Paul Turek, MD — Mon, 07 Nov 2011 16:00:55 +0000

What's inside of a coffee mug depends on how you look at it.

Do you think it is possible to have your own children with absolutely no sperm in the ejaculate?
Why yes. It happens on a daily basis in my practice.
Honestly, the word “sterility” has really lost much of its meaning nowadays with advances in reproductive technology.

The Affairs of Sperm

Azoospermia is the word used to describe the lack of any sperm in the ejaculate. It is a devastating thing for men to hear as they try to conceive. It comes in two forms: as a consequence of blockage in the sperm ducts outside the testis in the setting of normal sperm production in the testicle (i.e. vasectomy) or as a result of poorly functioning testicles and normal, open ducts beyond it. We routinely grab sperm from behind vasectomy sites to use with assisted reproduction to conceive. Finding sperm in men with poor sperm production, termed nonobstructive azoospermia, is a more complex matter.

One way to think about sperm production in men with poorly functioning testicles is to compare it to a mug with coffee in it. Say the mug is filled with ¼ cup of coffee. If you hold shake the mug, you may not see any coffee spill over the side. In this case, you might assume that the mug has no coffee inside. But, if you peer into the mug directly, you will see that there is actually coffee in the mug. Similarly, the testicle makes more sperm (coffee) than is found in the ejaculate (spilling over cup). There exists a threshold of sperm production, over which sperm shows up in the ejaculate and below which it will not. So, now you know the secret of making fathers out of “sterile” men with poorly functioning testicles.

Sperm from a Rock

Of course, it’s not quite that simple. There is one more layer of complexity here. Poorly functioning testicles may not make sperm evenly throughout their substance. In many cases, there are “pockets” or “islands” of sperm within a sea of otherwise empty tissue. Clinically, this makes sperm retrieval more difficult and has pushed this technology to a high art.

To find sperm, fertility specialists use several sophisticated approaches in men with nonobstructive azoospermia. The traditional testis biopsy works about 30% of the time to find sperm and, as a consequence, is no longer the de rigueur technique for this problem. Fine needle aspiration “mapping”, which I invented about 15 years ago, is easily twice as good as a biopsy in finding sperm and much less invasive. Lastly, “microdissection” of the testis another alternative and involves an all-out surgical assault on the testicle to find sperm making it the most invasive approach. The elegance and complication rates for these approaches vary widely, but their intent is the same: to find enough sperm to allow biological fatherhood. Importantly, when expertly performed, these techniques will find sperm in the majority of cases. For the remainder, there is hope as even newer “no touch” scanning technologies are on the horizon…

Timing (And Position) Are Everything

Paul Turek, MD — Mon, 18 Jul 2011 15:00:39 +0000

Does timing and position matter for sex like it does for surfing?

Missionary? Doggie? Cowgirl? Kneeling Lotus? Quarter moon? Full moon? No moon? Is there really a best lovemaking time or position to have a girl or boy?

History of Designing Sex for a Boy or Girl

Methods for determining baby gender are ancient, even prehistoric, and range from astrological, to dietary to positional. One of the earliest references to this concept is the Chinese Birth Gender Chart, said to have been discovered in a tomb near Beijing for where it lay for 700 years. It supposedly now resides in the Institute of Science in Beijing. It claims to predict the sex of the child from the month of conception and the age of the mother.

It has also been said the many myths about sex position and timing determining baby gender resulted from the mad rush of lovemaking that followed the end of the World Wars and the return home of soldiers. I’m sure this influx of war torn yet triumphant, and testosterone laden yet depraved men gave new meaning to the term “Honey, I’m home!” for many mid-century modern couples.

The Lovemaking Myths

Here are the most common myths regarding sexual position and timing to help get that boy or girl. Sorry, no pictures. I hear these from patients all the time, as they look at me bright eyed, with heads nodding, searching for my blessing.

Eat meat and salty food to get a boy.
Splurge on desserts to get a girl.
Both partners eat lots of fish and vegetables for a girl.
Make love standing or doggy style and during a quarter moon or at night for a son.
Use the missionary or cowgirl position and during a full moon for a daughter.
The Shettle method suggests having sex as close to ovulation as possible, for a boy, as boy sperm are less robust than girl sperm. Do the opposite for a girl.
If the male partner climaxes first, then a boy will be conceived. The opposite is suggested for a girl.

The Lovemaking Truths

Sorry to be the bearer of bad news. Despite all that you may have heard, there is no real data supporting the idea of a “best” position or time for sex to conceive a boy or girl. In fact, a prospective study of couples starting to conceive was actually published in 1995 in the New England Journal of Medicine that reported no relationship between the timing of intercourse and baby gender. Ah, but they did not study lovemaking position, thus keeping that myth and folklore alive! Come to think of it, that would be an interesting study to do, and one that I imagine would have no trouble enrolling subjects…

Women: They’ve Got Me Covered

Paul Turek, MD — Sat, 07 May 2011 07:09:42 +0000

There she goes again, rolling those eyes…

I think it was Jim Carrey who said, “Behind every great man is a woman rolling her eyes.” Ok, maybe that’s not always the case, but there are several women who have fundamentally shaped my life. Here’s my short list of Happy Mother’s Day recipients:

Mother: For obvious reasons (“I wouldn’t be here without you”), I honor you first. I remain only a couple of pounds heavier than I was in college because you raised us to believe that carob was tastier than chocolate and that a good orange is sweeter than ice cream. And thanks for the ongoing reminders to wear a coat when I go outside.

Oma (Grandmother) Turek: Although eulogized in this forum after your death at 99 years of age, you still inspire me daily to make a difference, never stop learning, do things well or not at all, and fight for what you believe. And, by the way, thank you for single handedly bringing our family to America from Czechoslovakia through Nazi Germany so that we could start a new life.

Tante (Aunt) Betty: Your life of 90 years was a study of consistency and habit. You were the family clock, sending cards on every occasion to everyone every year. Thanks for the $5 bill in each birthday card from you for 48 years and for teaching me the value of ritual to a full and considered life.

Sister Karin: Thanks for being that older sibling who always got better grades than I did in elementary school and for making straight A’s in school de rigueur for Mom and Dad. Never bothered me a bit that you could smoke all your classes and be a varsity athlete in I don’t know how many different sports.

Mother-in-law Thelma: Hard to believe that I am one of those guys who actually likes and admires his mother-in-law. Given your background as a published writer and English major, thank you for not constantly correcting my spoken word and for letting me wax as colloquially as I wish in my blog.

Dearest Ashley: How do I thank you? Wife, lover, friend, ally, competitor, teacher, closet politician, therapist and mother of our children. No limerick can hold a candle to your beauty and grace. And kudos to you for always letting me believe that I am running the show, and for never letting me see you rolling your eyes.

Royal Advice for the Ages

Prince William's personal royal crest.

Dear Duke and Duchess of Cambridge,

I watched your lovely wedding at Westminster Abbey this week. So sorry that I couldn’t make it to the Abbey for the ceremony, but I had to operate that day (and you didn’t actually invite me). All is forgiven, as I was privileged enough to watch the marriage (from the streets) of Lady Diana and Prince Charles some 30 years ago when I was in London as a college student doing research at St. George’s Hospital. It must have been a great affair and it looked like you both enjoyed yourselves immensely.

I know that it’s early in your relationship, but sooner or later you will look in each others’ eyes (or be told by the Queen) and say “it’s time to start a family.” Best be prepared as it’s gonna happen…to keep the lineage going and all that.

For this reason, I’m be happy to offer you some royal advice on this matter. No, don’t bother to thank me; it’s my pleasure to help out. Here are 10 tips for successful family building that I have handed out countless times to couples trying to conceive and it’s worked well for them. Feel free to tuck it away in your nightstand until the time comes or “ring me up” anytime you like:

Duchess Catherine, although you looked fabulous in that wedding dress, you really must put on a stone or two (a few pounds) of weight. Being too thin or too heavy reduces chances of conception. Aim for a body mass index of 19-25.
Duke William, spend a little less time with your buddies at the Mahiki or Pig’s Ear tavern and painting the town red; too much sauce (alcohol), fags (cigarettes) and fries (even with vinegar) are poisonous for sperm. Like I always say: All things in moderation; treat your body like a temple.
On that note, the “bangers and beans” served for breakfast at Bucky Palace do not constitute a good antioxidant diet for either of you. Take my advice and start on the Paleo diet, rich in fruits, vegetables and nuts along with occasional bison, boar or elk meat from the palace grounds at Balmoral.
Better yet, head south to the Mediterranean and eat like they do, as they have the single best antioxidant diet for a healthy heart and good fertility.
Surely it must be stressful to be a royal. And believe me, stress wreaks havoc on fertility as well as your relationship. How will you achieve that necessary balance in your lives? Avoiding the paparazzi is one way. Regular exercise, yoga, acupuncture and massage are others. Wouldn’t surprise me at all to learn that your level-headed grandmother isn’t doing something like this in her antechamber.
Duke William, stay out of hot baths, tubs, and saunas as these will drop your sperm count like a lead balloon. Showers are fine, especially gold plated ones.
Duchess Catherine, I know that you know that timing is everything. Well, it is also true of conception. Use basal body temperatures or ovulation predictor kits to let you know when to flash that great smile at the Duke.
Duke William, trying to conceive is like hunting. You need to know when to fire and when to reload the gun. Every other day is optimal for baby-making.
Duchess Catherine, consider cutting out the caffeinated coffee at the Ritz, as excess coffee consumption reduces fertility. I’ll get back to you about the tea there as it goes so well with the crumpets and finger sandwiches.
And both of you, get enough rest! For a good sex life, you need energy, you need to relax, and you need time. Remember that the mind is the largest sexual organ and it controls your “mojo” as Mr. Powers put it, so take care of it. Hit the kill switch on the TV and computer earlier in the evening. Turn off Facebook and face each other. Simply sleep; the sex will follow.

Men and Romance: Its Complicated

Paul Turek, MD — Sun, 13 Feb 2011 01:48:28 +0000

Believe it or not, men like chocolate hearts too…

The definition of the word romance in most dictionaries, including the mother-of-them-all Oxford English Dictionary, includes the statement “a love affair.” In real life, however, the word romance means entirely different things to men and women but there is probably some common ground here. I think that Robert Frost best summarized what we would all agree that romance is when wrote about “an irresistible desire to be irresistibly desired”.

Romance: A Man’s View

“Me Tarzan, You Jane.” It may start like this, but things evolve. As the hunter instinct fades, the nurturing phase begins. Instead of giving flowers, he shares his earnings. Instead of listening, he tries to solve any and all problems. These are subtle but practical ways that men use to take the relationships they covet to the next level. He may only buy flowers on Valentine’s Day but he fills the gas tank weekly. Think of it as the Elvis Presley, “taking care of business” concept.
His intentions are innocent. He believes that through a focus on being a protector and provider that he is meeting all of her needs.
For the most part, sex is not a symphony. Men tend to rush to the final movement without regard for the rest of the performance. Admittedly, there is room for improvement, here. One way for women to make ground here is to emphasize that it is clear that he loves the steak, but to save room for dessert.

Romance: What You Might Not Know About Men

A published survey in Psychology Today listed, in order of importance, what men like in romance. Believe it or not, presented here, from first to last, are their top 10 preferences:

Taking walks together
Kissing
Candle-lit dinners
Cuddling
Hugging
Flowers
Holding Hands
Making love
Love letters
Sitting by the fireplace

So, it appears that men may not actually come from Mars after all. And, please note that romance, although not a vocabulary word used by most men, is something deeply felt nevertheless.

Tips For Valentine’s Day

What is all of this leading to? A succinct, practical, digestable and romantic set of tips for Valentine’s Day:

Give your partner a compliment.
Indulge in your favorite taste treats.
When the lights go out, turn the TV (read: computer, phone, ipad) off.
Go to bed at the same time.
Get the kids out of the bed.
Music moves the soul; listen to your favorite tunes.
Don’t underestimate the power of the kiss.
Mix up the sex. Gourmet, home-cooked and fast food varieties all have a place.
Say, “I love you.” Women need to hear it and men need to say it. After all, we all agree that fundamental to romance is a love affair.

That Azoospermic Feeling

Paul Turek, MD — Tue, 08 Feb 2011 06:09:48 +0000

Was Van Gogh Azoospermic?

At the beginning of the office visit, I like to ask men with no sperm in the ejaculate who are unable to conceive a simple question: “What crossed your mind when you first heard that you were azoospermic?” The answers varying greatly but are very telling:

“It must be a mistake.”
“I shouldn’t have joined that fraternity in college…”
“It wasn’t the best sample I’ve ever done.”
“I was simply and utterly devastated.”
“I was in shock and then got really depressed.”
“It changed my life…I always thought that I would be a father.”

The Meaning of Azoospermia

Azoospermia is the lack of sperm in the ejaculate. It can be due to a blockage in the system (obstruction) or failure of the testicles to make sperm (nonobstructive). The most common reason for blockage is a vasectomy. Other causes include infections, prior surgery, injury or congenital absence of certain reproductive tract organs. Failure to make sperm can be due to exposures (hot tubs), medications, varicocele, a history of undescended testicles, cancer and cancer treatment. However the largest chunk of men with poor sperm production have none of these issues. Instead, they have a subtle genetic cause: either they are missing genes on the Y chromosome or have other chromosomes harboring subtle alterations that do not otherwise affect their health or lives.

So, like Captain Renault in the movie Casablanca, most men with azoospermia are “shocked, shocked!” because they feel so normal in every other way. And the vast majority are normal (as normal as men can get) in every other way. Most of the things they worry about, like college indiscretions, are exposures that are entirely reversible with time. My response is usually to allay fear and guilt by saying: “This is not something that you have done to yourself; let’s see if we can do something about it at this point.”

Treating Azoospermia

In fact there is a whole lot that we can do with azoospermia. Men with blockages can often be unblocked with microsurgery, one of my favorite things to do. This gives them the chance to conceive naturally again. And most men with poor production as a cause of azoospermia will have pockets of sperm in the testicles that can be identified by techniques like sperm mapping and that can be used for high-technology pregnancies.

What I have learned after caring for hundreds of azoospermic men over two decades is that they really don’t care what their sperm counts are as long as they can be fathers. And once they are fathers, it is clear that that “azoospermic feeling” goes away, as it should.

Dawning of the Deed

The official photograph of the world's oldest embryo

Here’s a good question: “How old is sex?” You know, the old birds and the bees-type hooking up. Recently, some fossil finds have given us great clues as to the age of intercourse, the conception of copulation, the dawning of the dirty deed.

You might have trouble even imagining your parents or grandparents having sex, but intercourse is at least 375 million years old. That’s quite a tradition to carry on and we should do it proudly.

See, before sex there was “spawning,” characterized by an utter lack of intimacy. Despite this, it is still pretty popular today, occurring in well over 90% of fish. Basically, female fish lay eggs into the water and the males then deposit sperm into the water to fertilize them. The embryos that develop are on their own and out in the open. With intercourse came fertilization of eggs within the female body, removing risk to embryos associated with all of those nasty creatures found in pond water.

Until recently, it was believed that sharks (yes sharks) were the first species to have sex and give birth to live offspring. Funny, it’s hard to imagine sharks as particularly romantic, but as they say, you can’t always judge critters by how big their teeth are. I just met a walrus with 2-foot tusks who is the nicest guy you ever met.

What changed all this was a small fish fossil that was found in a piece of limestone on a cattle ranch in Western Australia. About the size of a mackerel, this female fossil contained an embryo within it, along with a petrified umbilical cord. Proof positive: Internal fertilization in backboned animal before sharks, 375 million years ago.

So, if you think the sexual revolution happened in the 70’s or is happening today, you’re wrong. The real revolution in sex occurred during the Devonian period, way before you were a twinkle in anyone’s eye.
