This is the second of two guest posts from a patient who lives in Europe. He recently recontacted me about his experience with male infertility and how it affected him. Moved by his story and by his emotional fortitude, I asked him if he could share his remarkable journey with others. The first post is from March 12th.

I had to face the fact that I was my own worst enemy. This was an epiphany for me. By becoming a negative person, spontaneity and creativity had left me, high and dry. And gone with it was the ability to problem solve. For me, once of the hardest things that I have ever had to do in my life was to admit that I was the root of the problem, that I was responsible. The epiphany was that because I was the problem, I could also be the agent of change. I could own this. The rebuilding of me had to start with me.

It was at that point that I reached out to a psychiatrist, Our talks helped me find my way back. Honestly, I never knew that these sides of my character even existed, and was even less aware that they would belch from my soul as they did. These sessions allowed me to vent my feelings and, over time, I felt better and better. It felt like I could take the 800-pound gorilla to the doctor’s office and leave it there. And, funny enough, the “gorilla” began shrinking in size with each session, almost to the point of becoming a small, friendly monkey. And although even cute little monkeys can be annoying, these sessions helped me enormously by providing tools and methods to help me better understand, accept and manage such strong feelings.

Modern societies of any culture, Western or Eastern, are not great at raising men to be in touch with their emotions. And realizing that you are infertile is a very hard blow to one’s manhood on many levels. One of the most concerning issues was worrying about what others were thinking or knew about my situation. Early on, it bothered me to think that they would find out. As I began to heal, however, I began to care less and less about what others thought. I simply can´t control other people’s minds and have no interest in doing so. I also realized that those who are close to me all know about the infertility and nothing has changed between us and how the view me as a person. The rest I leave in God’s grace.

Another realization over the last year is that infertility is not a disability in life. It is in fact the way that I was created. It is part of me. It is who I am. And although I can’t change it easily like, say, losing weight or getting more exercise, I can certainly change how I view it. I can shape my future in any way that I wish. I am the master of me.

The road I took that year was no easy one, but I made it through the year. Leaving this behind me, I can now move forward in my life. I have faced the demons and have come to terms with my reality. I now look upon the future with renewed eyes and see a future filled with happiness despite the fact that I cannot have children.

Please let us know if you would like to continue a discussion of these issues in an on-line forum…

A Year Without Answers

This is a guest post from a patient who lives in Europe. He recently recontacted me about his experience with male infertility and how it affected him. Moved by his story and by his emotional fortitude, I asked him if he could share his remarkable journey with others.

“The day we met with Dr. Turek was a week filled with hope and happiness. Almost a year earlier, on the same day, I went through a biopsy with the result that there were no sperm. So when we found out about Dr Turek, this really felt like the last chance, the last hope. Therefore the decision to travel across the world to see him was an easy one. The visit and procedure went well, but, again, the result from mapping showed no sperm. And no answer as to why this is.

It has been a year since I spoke with Dr. Turek about these results, a year characterized by disappointment, anger, sadness and worst of all, no answers. There were simply no answers to be found. Why me? Why now? What now? Literally a thousand questions ran through my head interfering with my daily life, keeping me up at night and affecting my relationships. I had never felt anything like this before.

I wanted so badly to not feel alone in this. I wanted someone to understood my plight, without me having to explain every small detail, because you can´t explain this feeling.

I needed to talk about it. I just couldn’t bury it. But, who was I going to talk to? And what would I talk about? I felt isolated as there appeared to be a big taboo regarding this topic. Anyone I spoke to told me focus on other things in life. But how are you supposed to do that when all you think about is the fact that you can’t have your own children? I knew no one with a similar experience who would step forward and talk about his experiences and feelings. Google searches were pointless, as the Internet does not care and information on coping is useless.

That year was best characterized by the feeling of being lost and trying to find my way in darkness without a map or light. I felt that I was in a deep, dark place, especially when I tried to look forward into the future.

Feeling alone, I began suppressing everything. All feelings, thoughts and discussions were avoided. I told my close family that I did not want talk about this matter anymore. It was a buried subject for me, never to see the light of day again. The reason for this was that talking about this issue within the family only made things worse. One problem with this approach was that the bright spots in my life also suffered along side. The subject became an 800-pound gorilla that, although ignored, never left the room. Maybe the gorilla was bigger than 800-pounds as the family dynamics changed greatly.

Then I became angry, sometimes uncontrollably. This was when I could see that I was approaching rock bottom. The slightest annoyance, comment or action sent me into a furious rage where I often exploded at whomever was next to me. Many times it was my wife, which led us to the brink of divorce. We were both tired of fighting and there appeared to no other solution to end the fighting but dissolving the marriage. This moment was a real eye opener for me.

What helped keep me going to some degree during this time was my job. As a futures trader, my work was very involving and in the moment. Believe it or not, it was also logical and predictable, in a mathematical sort of way. It could be explained and reasoned with and while doing it, I could leave all my troubles behind. But I couldn´t hide in my job forever.

I turned the corner at rock bottom when I realized that if I did not start controlling my emotions and start being honest with myself, my life as I knew it would change dramatically. It was on that day, a very cold one in December, that I realized that I was just too exhausted to continue to fight with myself and others. I couldn’t bear to face another year continuing on the same as the last. So, I stopped lying to myself and began to face the reality of my emotions.”

It’s in the Steak

Paul Turek, MD — Tue, 21 Feb 2012 16:00:48 +0000

Hope is a core value of children (Drawing courtesy Sophia Turek, age 7)

In quiet moment on the couch, I recently asked my 8-year old daughter what the word “hope” means to her. “If life were a meal, hope belongs in the steak,” she said.

The food metaphor didn’t surprise me, as with most kids her age, she thinks about it a lot. What did interest me was that, in her view, hope takes center stage. It’s not the cupcake for dessert. Or a sweet milk shake, or potato chips. To kids, hope is serious stuff, right smack in the middle of the main meal. Just a hunch, but I am convinced most adults would not put it there.

A Telling Telephone Call

He called from Kentucky. Having read about our recent research story about obtaining grant funding to build an artificial testicle, he wanted to know more. As a cancer survivor, he had no chance of fathering a child. He asked great questions about where the research was going and the expected time line for generating sperm from stem cells. I answered frankly as I am not a fan of dangling carrots or pipe dreams in front of others. He listened intently and thanked me kindly. I asked him to keep in touch, and that was that.

Little did he know such brief but meaningful conversations stokes my fire and fuels me to imagine, begin, execute and finish such far-fetched research projects.

Little did I know how that single, brief exchange also affected him. The next day, the Clinic received a new Yelp review (don’t get me started on this…just compare the visible reviews on the page with the invisible “filtered” accessed at the bottom). Curious, I read it. It blew me away. It went something like this (edited for brevity):

“H-O-P-E; that’s what Dr. Turek has given me; new found hope…..” After a 16-year nightmare with testicular cancer, once in 1996 and again in 2002, a good friend of mine forwarded me the most shocking, exciting, uplifting, inspiring article I had EVER read. I anxiously and carefully read it word for word, line for line, as I could not believe what my eyes were reading and my mind was comprehending. My instinct, was to call Dr. Turek’s office immediately as I was yearning for more information.”

“After talking with his office staff, a phone conference was scheduled for Dr. Turek and I within the next 3 days…Dr. Turek gave me “me” and he gave the rest of the testicular cancer world a vision that we never imagined possible… I will strive daily to do everything in my power to assist Dr. Turek in seeing this miracle discovery come to life. I will do whatever, whenever, whereever it takes to be a part of this life changing miracle. I am inspired, encouraged, and relieved with the hope of tomorrow for me and for others.”

For the first time in years, the man from Kenucky felt a ray of hope. And in some small way, his life is different today than yesterday.

Hope not Hype

So what is it about being an adult that takes the hope out of our “steak?” Why do long, strong doses of reality make it harder to dream the unimaginable? There is so much promise in hope that I, for the record, refuse to give it up. I agree with the old French Proverb that “hope is the dream of a soul awake.” You can expect more of the unimaginable out of me before my time is up on this good earth.

The Artificial Testicle: Funded!

Paul Turek, MD — Mon, 02 Jan 2012 16:00:01 +0000

Whole Earth Catalog: the old Google, according to Steve Jobs

It is the stuff of dreams in academic medicine: an NIH (National Institutes of Health) research grant. Get one of these and you’re pretty much assured of getting tenure and succeeding at any major U.S. university. It is the ultimate stamp of approval from the government and society that your thoughts and ideas have merit and value.

And I was just awarded one!

NIH Funds the Artificial Testicle

Yes, the federal grant that we submitted recently to build a human artificial testicle was funded. To be clear, this grant is not about creating a testicular implant for a man who is missing a real one. We did that a decade or so ago. This award is to develop a sperm making biological machine. I wrote it along with Dr. Connie John, CEO at MandalMed, Inc., a biotechnology company in the Bay Area. We now have a couple of years to create human artificial sperm in a dish, or more formally, a “bioreactor.” A fancy dish to be sure.

You’ve seen the posts on how successful this research has been in mice models using various stem cells as a starting point: embryonic stem cells, adult stem cells and early germ line (spermatogonial) stem cells. In labs all over the world, real, live, fertile sperm have been made in animal models from each of these stem cell precursors. Honestly, given this success over the past several years, surely we can figure out how to do the same in humans.

Why Do I Need NIH Funding?

Funny thing is, I am not in academic medicine anymore. No tenure to deal with and no need to prove anything to anyone but myself and to legions of loyal patients who depend on cutting edge innovation for their infertility care. Personally, feeling the suffering of patients with infertility is far more motivating than doing science for the sake of science, or for the sake of tenure.

Not to compare myself to Steve Jobs in any way, but I can’t help think one of his favorite mottos from the Whole Earth Catalog. This is what guided him in his quest to build a better computer for everyone: “Stay hungry; stay foolish.” It feels absolutely fabulous to be able to dream it, write it and finally to do it. The essence of science for the good of people.

Effort to Build Artificial Testicle Awarded NIH Grant

Proposal to make human sperm from stem cells receives government funding

Newswise — SAN FRANCISCO, CA. January 9, 2012. Dr. Paul Turek, Director and Founder of The Turek Clinic, a men’s health medical practice, and Dr. Constance John, chief executive of MandalMed, Inc, a San Francisco-based biotech company, were recently awarded a Small Business Innovation Research (SBIR) grant from the National Institute of Environmental Health Sciences (NIEHS) of the National Institutes of Health (NIH) to construct an artificial human testicle and research how sperm are made from stem cells.

“Fertile sperm can be made from various stem cells in mice, but making human sperm from these same sources has been elusive,” says Turek, a practicing male infertility specialist in San Francisco. In this project, they will try to produce mature human sperm in a live laboratory model of a human testicle.

This work extends on previously published research by Dr. Turek on human testicular stem cells, the forerunners of sperm. Dr. John is an expert on human Sertoli cells, which critically nurture sperm as they develop in the testicle. “This grant is quite an honor and comes after several years working together on this idea,” notes Turek. “We have assembled a great group of scientists who are very committed to its success.”

A functioning artificial testicle has important implications for the field of reproductive biology. It could shed enormous light on the intricate details behind the mysterious and complicated process of spermatogenesis or sperm production. Even further, it could be used to later develop patient-specific, fertile sperm for men who simply do not make sperm due to genetic or acquired causes.

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…

The Recipe for Man Made Sperm

Paul Turek, MD — Mon, 08 Aug 2011 15:00:32 +0000

Will stem cell "recipes" become as tried and true as the ones in this book?

Stem cells rock. While the stock market tumbles, stem cell science is sizzling. I know, you’re thinking: what is he talking about? No diseases have been cured with new stem cell technologies. But, from what’s being discovered almost weekly now, I can tell you that male infertility is likely to be one of the earliest boxes ticked on the “Diseases to Cure” list for stem cells.

Sperm from Stem Cells

Honestly, stem cells appear to be great to use to create sperm. Just a few posts ago, I shared the exciting findings from a group in Japan who took stem cells from newborn mouse testicles, placed them in an “organ culture” system (basically Jell-O), and grew mature, fertile sperm in the laboratory. Over the past 2 years, my colleagues at Stanford have also shown that human embryonic stem cells can be pushed along the path toward sperm in a dish. They also showed that adult stem cells from places like skin can also be driven in the same direction. Not all the way to mature sperm, but certainly more than half the way.

Overcoming Sterility in Mice

Last week, researchers at Kyoto University in Japan brought man made sperm closer to reality…at least in mice. I know many of you aren’t really worried about infertility in mice, but we have to start somewhere.

In a study published this past week, they took embryonic stem cells from mice, the mother of all cells, and watched them closely as they began to develop into other cell types (i.e. differentiate) in a dish. After several days, they plucked out rare and transient downstream stem cells called the primordial germ cells and transplanted these cells back into sterile baby mouse testicles. And sperm were made. Good sperm. Genetically intact and fertile sperm. Sperm that led to offspring that were also naturally fertile. And they did the same experiments with adult stem cells and got the same result, eliminating the need to use embryos at the start.

Please realize that this success did not happen overnight, but was the result of good, wholesome science and lots of sweat equity. And not all the results were rosy: primordial germ cells are rare, short lived and inefficient. In addition, when slightly different cells were injected into testicles, benign tumors formed, the scourge of stem cell science. So now you understand why mice experiments come first.

Stem Cells and Human Male Infertility

Imagine this: A boy has cancer and gets cured by being pounded with chemotherapy. Easily enough treatment to sterilize him for life. After that, his testicles could make sperm, but the “seeds” (early germ cells) that develop into sperm have been wiped out. Solution? A skin biopsy. Turn it into an adult stem cell and inject it right back into his testicles. And ta da! Sperm. I can’t stop thinking about how possible all of this is, as stem cell recipes are perfected. As Ted Allen, The Iron Chef once said: “There are two words to improve any dish: Ba-Con.”

Mice Sperm in a Dish

Paul Turek, MD — Sat, 09 Apr 2011 15:11:11 +0000

If they just would have included a photo of the finished product…

It’s not the mother load of discoveries in our field, but it’s pretty close. It tells us that the mother load is definitely out there…and within reach. Yup, the good news is that real. live, old-fashioned sperm were made in a dish… at least for mice.

The Holy Grail: Artificial Sperm

For the 55,000 reproductive age cancers survivors annually in the U.S. and a host of other men who are sterile due to injury, genetics, exposures and the like, this is good news. Despite the availability of utterly fantastic reproductive technologies like sperm mapping, in vitro fertilization and intracytoplasmic sperm injection, some men still do not have sperm to use them. The standard of care in reproductive medicine today is a sperm: a mature one, with a tail, and hopefully moving or at least alive.

And the sperm can come from anywhere. Often, men with no sperm in the ejaculate will have sperm within the reproductive organs such as the testicle or epididymis. These sperm work great to help them become fathers. But there are many other men do not have any sperm, anywhere, especially men with childhood cancers who were blasted with sterilizing treatments before they even reached puberty and made their first sperm. Clinically, I see these patients all the time and this is the crowd of men I am very motivated to help in my short time on this good earth.

The Finding: Functional Sperm for Mice

The recipe to produce functional sperm from stem cells precursors has eluded researchers for 50 years. There have been many false starts, including the last one in 2009 out of Newcastle that was published and then retracted from print by the editors one week later. But, a group from Yokohama City Japan nailed it and recently published functional mouse sperm from testis stem cell precursors.

From reading the paper, it is clear that it took several years of constant, diligent work to find the key ingredients to make it happen. In my opinion, the secret sauce was that our recent, vastly improved understanding of stem cell biology really enlightened the science. They took testicular tissue from newly born mice that contained only stem cells (no sperm, just sperm precursors) and put them in a jello-like environment. Getting them to grow was the trickiest part and finding the right food was also critical.

How is This Sperm Different?

What made this paper great was that the scientists made reproductively “competent” sperm. They took the artificially created sperm and used them with high technology approaches to create baby mice. Then, they let the baby mice grow up and mate. Remarkably, the offspring of these mated mice were normal. Can’t ask for much more from a sperm now can we? Many have tried, including some of my closest colleagues, but no one has gone this far before. Bravo!

So now, all we have to do is replicate this in humans, something that I have been pursuing for several years with colleagues. What is so uplifting for me about this paper is that it seems that making human sperm in a dish is really more evolutionary than revolutionary science. I better go buy some more of that midnight oil….

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.

Babies…Naturally

Paul Turek, MD — Sat, 14 Aug 2010 15:35:08 +0000

The magic bullet? You decide.

In my daily fertility practice, while trying to help couples to conceive, I’ve noticed a trend lately. Patients are less interested in using high levels of “assisted reproduction” to have children. In particular, they would like to avoid in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), the Cadillac of all techniques. Even before they meet me, they have decided against it. Not all couples, mind you, but certainly more than before.

Briefly, IVF-ICSI is a busy month for women. It involves stimulating them with daily, injectable hormones during the first half of the menstrual cycle to generate more eggs than normal within the ovary. Ovulation of eggs is induced by injection of a second hormone, which is closely followed by egg retrieval using needle aspiration under anesthesia. Retrieved eggs are then stripped of their cell coats in a dish and a single sperm is individually injected into each egg by an embryologist. The criteria for choosing sperm are: good looking and hopefully moving. Eggs then become embryos in a Petri dish and are transferred back to the female reproductive tract three to five days later, depending on how they develop. Extra embryos can be frozen for future use. A pregnancy test is obtained two weeks later.

As a male fertility specialist whose practice mantra has been “treat the male, cure the disease,” I find this trend very interesting. Assisted reproduction is almost always an option for couples, but I have spent a good deal of time publishing research showing that classic male infertility treatments such as varicocele repair and vasectomy reversal are very cost-effective ways to conceive compared to more expensive techniques like IVF-ICSI. On the other hand, these techniques are the only option for many men with azoospermia, or the absence of ejaculated sperm, and I am glad that it exists for this.

I wrote down what patients said when I asked them why IVF-ICSI is not an option on the table for them and here are some of the responses:

“It seems pretty invasive and unnatural.”
“Isn’t it relatively new?” (IVF is 32 years old, ICSI is 18 years old)
“Who selects the sperm?” (Since it is not God or Darwin)
“Wasn’t ICSI developed as an experimental mistake?” (Yes)
“How do we know that those are our eggs and our sperm? (Rare)
“It’s only a single try at having children.” (Maybe two)
“Isn’t there an issue with higher birth defects and syndromes in babies” (Very likely)
“Are our children going to be infertile?” (Unknown)
“We’d prefer to have the hope of trying every month at home.”
“IVF-ICSI is too expensive”

What I think is happening is that as IVF-ICSI is being offered to consumers more often than ever (currently 1-2% of U.S. babies are born from these techniques), patients are becoming better educated about the technology and are making more informed, personal choices. My gut also says that good, old-fashioned sex has a strong following among infertile couples as a way to conceive. In the words of Woody Allen in Annie, “that was the most fun I’ve ever had without laughing.”

Adding Hope to Health

How about being happy and hopeful as well as healthy?

The couple had been trying to conceive for 5 years unsuccessfully. The tension and anxiety in the relationship was palpable and strained. They had spent well into the 5 digits to have a child with test tube baby technology (IVF) and yet were still not pregnant. His vasectomy reversal had also failed them. And they were going to try one more time, just once, with me, before calling it quits.

When he came to me for care, he was frankly depressed. Out of money and full of debt, close to losing his job in this economy and in a strained relationship hanging on by a thread, he sat across from me. He looked terrible. “Can you help?” he asked me.

Well I did help. I reversed his vasectomy again and it worked. Fast-forward 9 months and a birth announcement arrives in the office from the couple with a long personal note of thanks on the back. But one line really struck me:

”Looking at her, sleeping quietly, I see her future as an astronaut, the President, a doctor, a lawyer or anything else that she wants to be. She can be or do anything!”

Absolutely unbridled hope and enthusiasm was infusing a mind once filled with almost unfathomable despair. All this change, nine months and one baby ago. Wow!

Talk about a biological drive. Reproduction easily ranks up there with breathing and eating. Not for everyone of course, but for many. I am quite sure that if you surveyed infertile couples about their quality of life with infertility, as has been done in patients with cancer, you would find these diagnoses equally impactful. I have no doubt many of my patients would give up five healthy years of their life to have a child. Maybe even 10. Just because it cannot be assessed by a blood pressure cuff, a blood test, or a scar does not make infertility any less important an affliction.

And yet, despite its profound impact, its ability to tear apart relationships, crush self-esteem and slow down an otherwise productive couple to a grinding halt, infertility is not really considered a disease in many societies, including ours.

Want a more productive and healthier society? Cure infertility. And what about something else that this world could use a lot more of, as expressed by my patient: the resurrection of those elemental feelings that lead us to live good lives and to make the world a better place for those who will follow us.

The Quiet After the The Storm of Cancer

Throwing a wrench in the machinery of sperm production…

I have to admit, the testis “mapping” procedure that I developed some years ago has truly been a workhorse technique for my male infertility practice. And for the practices of other male reproductive specialists around the world as well. Creating fertility from sterility. I bring it up again because it is gathering more attention in the press as this week we recently published another paper that highlights its utility—this time in cancer survivors.

In a related study from 2002, we published that the majority of men who had been exposed to chemotherapy for cancerous or non-cancerous disease and who were “sterile” afterwards have sperm in the testis that can be safely used for fatherhood with assisted reproduction. Fine needle aspiration (FNA) mapping was employed in this study and its potential to help cancer survivors to conceive was convincingly demonstrated. The recent paper expands that group of men to include those who received not only chemotherapy and radiation therapy but also a relatively extreme treatment for certain cancers termed bone marrow transplantation.

Let’s back up a minute for a biology lesson. How does chemotherapy affect a man’s fertility? Well, the basis of its effectiveness in curing cancer is that chemotherapy preferentially kills rapidly dividing cells more than slowly dividing cells. In general, cancer cells divide more rapidly than do normal body cells. The term for this difference in cell susceptibility is “therapeutic index”. Unfortunately, sperm are also produced very rapidly (about 1200 sperm are made every heartbeat) and therefore sperm precursor cells are also very sensitive to the effects of chemotherapy. Think of sperm production as a rapidly turning set of gears and chemotherapy as a wrench being thrown into them. Ka-chunk! Machine comes to a loud and crashing halt. Sperm production is over, or tremendously slowed down. The same action is true for radiation therapy treatment.

Now, imagine not just one small wrench being thrown into the gears, but a huge wrench (or many wrenches) being suddenly thrown into the machine of sperm production. The result? More damage to the sperm-making machinery and a much higher chance of sterility. This is the essential difference between the patients from the 2002 paper on mapping and the most recent one. The cancer survivors in this week’s paper got blasted with the heaviest doses of chemotherapy imaginable, and topped off with a dollop of radiation therapy just to be sure. Hard to believe, but they also had usable pockets of sperm in their testicles. And normal babies as a result.

So, with techniques like FNA sperm mapping, there continues to be hope and good news about fertility after the storm of cancer treatment has passed.

Keeping the Family Jewels Shining

Heirlooms for the species.

As a living, breathing being on this good earth, we tend to take things for granted. The ability to have offspring can be one of them. That is, until the day that a serious medical condition like cancer rears it ugly head and puts childbearing at risk. In addition to the sterilizing effect of cancer treatments, the mad rush to treat the disease often marginalizes efforts to preserve fertility. Fire all the canons and check for collateral damage later.

Fertility preservation seeks to protect men, adolescents and children from a common, serious and impactful side effect of cancer treatment: infertility. The goal of fertility restoration is to empower patients who are cured and potentially infertile to bear children. These related fields have burgeoned recently because medical care is now shifting from curing cancer to improving the quality of life among survivors. And without a doubt, for many, fertility is a key quality of life issue at some point. Thankfully, exciting new methods of restoring fertility have already been developed and even newer technologies are under study.

Classic techniques for fertility preservation in men include gonadal shielding and sperm banking. Gonadal shielding uses lead-based devices to protect the testicles from being struck directly by sterilizing radiation treatment. Sperm banking is the process of freezing healthy sperm before cancer treatment begins for later use to conceive. But there is more. For patients who are too young to bank sperm, for those who have precious little time to bank sperm, or for those who have no ejaculated sperm to bank, testis sperm retrieval by biopsy (TESE) or needle aspiration (TESA) for banking is now possible before cancer treatment. In fact, in some cases of testis cancer, it is possible to remove only the cancerous nodule instead of the whole testis, or to freeze sperm from the testicle after it is surgically removed. These are now routine ways to preserve fertility in men.

Fertility restoration for men has also seen real advances lately. Sperm “mapping” is an innovation that I developed for men who survive cancer treatment but have no sperm in the ejaculate. It non-invasively and non-surgically deciphers whether there are small numbers of mature sperm in the testis, too few to get into the ejaculate, but usable nonetheless. In men who sustain nerve injury from cancer surgery and who are unable to ejaculate, a special medical instrument can produce an ejaculate for fertility purposes in a process termed electroejaculation. Techniques such as these are valuable tools to help men deemed “sterile” after cancer treatment to become fathers.

One of the most exciting areas of fertility restoration involves stem cell technology. Yes, the “promise” that we have all heard about stem cells curing disease will likely find its way into the fertility field as well. In pre-pubertal boys with cancer, ejaculated sperm is not present. Despite this, it may be possible to freeze the early stem cells from the testicles of boys before sterilizing treatment. After thawing, these “adult” stem cells may later be used to create sperm after further growth in a Petri dish or after transplantation back into the same individual. Also on the horizon is our ability to take skin cells from a sterile man, convert them into an embryonic-like stem cells and then “drive” these cells to become mature sperm in a dish–a true “artificial testicle.” So, with the belief that hope can cure misery, the world of science has taken fertility research from science fiction to reality. Not convinced? Stay tuned!
