Petroglyphs and Paleo: Inspiration for Essential Beginnings

Honestly, my opinion about nutritional supplements has evolved dramatically. Historically, the value of prenatal vitamins for women is well recognized and uncontested. For example, calcium keeps mom’s bones healthy as developing fetuses borrow mom’s calcium for their own bones. And iron prevents the anemia of pregnancy. Folic acid clearly prevents neural disorders and birth defects in children. No doubt, prenatal vitamins for women make sense.

Do Vitamins Treat Cancer?

However, with heart disease or cancer, the story is quite different. In 1998, the government set out to test herbal and other alternative health remedies to find the ones that work for cancer and other diseases. After spending $2.5 billion, the disappointing answer was that none of them help prevent or treat these diseases. As noted here several years ago, vitamins got an “F” for cancer. To top this off, newer data from just last month suggests that excess vitamins supplements may actually lead to an earlier death. Now what’s a guy to do?

Do Vitamins Help Men Conceive?

Thankfully, what is more encouraging is the value of antioxidant supplements for male infertility. In 2011, An august research group in England published a Cochrane Review that analyzed 34 studies of 3876 infertile couples using assisted reproduction to conceive. The meta-analysis found that the partners of men taking antioxidant supplements were 4-fold more likely to get pregnant and 4-fold more likely to give birth than couples in which the male partner was not taking supplements.

The Idea of a Male Prenatal Vitamin

This study changed my worldview to the following:

1. A large chunk of male infertility (maybe half) is due to what’s called “oxidative stress.”
2. Antioxidants are a good defense against oxidative stress.
3. The best antioxidants are found in the diet, and the Paleo diet appears to be the best.
4. Most men have terrible, antioxidant-poor, diets
5. If men ate more fruits and vegetables, maybe fertility would improve.
6. Barring this, men should view antioxidant supplements as prenatal vitamins.

The Essential Beginning

Motivated by this epiphany, I and several trusted colleagues, including fertility physicians and nutritionists, set forth to create a male prenatal supplement that would be better than eating airport food for fertility. We wanted it to be made in California and support the local economy, be certified-organic, and to reflect the latest findings in antioxidant research. It would contain vitamins, minerals and organics with high bioavailability, instead of just putting stuff on a label without regard to whether or not it is absorbed well by the body, like most other supplements. We wanted it to be available online, to avoid the middleman markup, and to be reasonably priced.

After a year of pretty intense work, it has arrived. It is called XY (your chromosomes, get it?). And not only that, we continued our research and developed an entire fertility product line for women all the way from pre-conception through breast-feeding with XX (women’s prenatal), Z (pregnant prenatal) and Z+ (post-natal and breast feeding).

Do all men need a male prenatal? Probably not, because as I said, nothing replaces a healthy antioxidant diet. But if you are like most of us, creatures of habit eating airport food and busting our chops to put food on the table daily, it is to you that I dedicate Essential Beginnings, XY.

Whipped cream: an unnecessary evil.

You have often heard me say that sperm production is an engine that really wants to run hard and fast. And, that by not taking great care of yourself, sperm quality and fertility can suffer. Given that 1 in 3 Americans have it, one of the biggest elephants in the room is obesity. Now, the literature is oozing with new data that puts real live numbers to the obesity and fertility problem.

Obesity and Sperm

As discussed before in this forum, there appears to be a direct relationship between a man’s weight and not only his semen quality but also his fertility. However, a brand new study out of Paris has now put more meat on this bone. In this meta-analysis of 14 prior studies and 10,000 subjects, new facts were put forth on the obesity and infertility issue. Here they are in a nutshell:

• Obese men are 42% more likely to have low sperm counts than men of normal weight.
• Obese men are 81% more likely to be sterile (have no ejaculated sperm) than men of normal weight
• For every 20 pound increase in a man’s weight there is a 10% increase in the chance of infertility

Is that enough fodder to make the changes you need to make? If not, then read on.

Fat and Male Fertility

Clearly, a large chunk of the obesity problem is related to diet. Junk in means waistlines out. In the first study of its kind published last week, researchers from Harvard collected semen samples from 99 mostly (71%) overweight or obese infertile men and assessed the fat intake in their diets over the previous year. Here is what they found:

• Eating a lot of saturated fats was associated with lower sperm counts
• Eating omega-3 polyunsaturated fats — the fats commonly found in fish and plant oils — was associated with better quality sperm

Of course complicating the study is the fact that most of the men were obese and all of them were infertile. Although the study included weight in the analysis, they did not consider conditions such as diabetes, heart disease, cholesterol issues and sedentary lifestyle that are associated with being overweight. Ultimately, such “details” have been known to kill a study over time. Regardless, dietary fats are now key suspects in the link between obesity and infertility. In other words, sperm are feeling the weight of obesity.

Now What?

As a men’s health specialist, I am always searching for lifestyle changes that can improve male fertility and health. As you can imagine, I was ecstatic to publish the first paper linking hot baths to lower sperm counts, as this identified an easily modifiable lifestyle issue: just say no to tubs! Well, here, my friends, is another one: Losing weight and eating well. This is a good thing! Maybe not as easy to fix as getting out of tubs, but one that is also much more germane to a long and prosperous life. So try The Turek Clinic Weight Control Plan. I have heard nothing but good feedback.

Honestly, it seems like testosterone is to blame for everything these days. The epidemic of low testosterone has been linked to economic recession, wars, bank failures and even global warming. Ok, so maybe I am exaggerating, but many men feel (or are told) that their testosterone levels are the root cause of much of the way they feel. Leaving aside causality and association, what can you do about it?

Testosterone and You

I am the first one to say that testosterone is important for a healthy, long life. Clearly, men with low levels, termed hypogonadism, do not live as long as men with normal testosterone levels. I understand too, what testosterone isn’t and can’t do.

So, I am entirely empathetic to patients who ask: “Doc, what can I do to naturally increase my testosterone levels?” Forget about expensive gels, creams, injections, pellets or patches of testosterone that have side effects. They want to know what they can do, on their own, to improve their testosterone balance. As a big fan of self-empowerment, I dedicate this post to these men.

Lifestyle Changes to Improve Testosterone Balance

1. Lose weight. Fat converts testosterone to female hormones called estrogens. Less fat means less circulating female hormone levels.
2. Exercise. Although it is true that while you exercise, testosterone levels may be lower, exercise stimulates muscle recovery and growth through increased testosterone at rest.
3. Don’t overtrain. Rest between exercise sessions allows testosterone to work its magic.
4. Get good sleep. Poor sleep habits stress the body as a whole and stress reduces testosterone levels. Perpetual jet lag is no place to be.
5. Eat smart and cut the alcohol. Eat healthy meals regularly; skipping is not allowed. Also cut down on alcohol as it tends to impair testosterone production and increase conversion to estrogens.

Dietary Supplements That Improve Testosterone Balance

1. Get zinc. Zinc is a co-factor for testoterone production. Oysters, peanuts, chicken, lamb and (how timely) pumpkin seeds are excellent source.
2. Get vitamin B. This vitamin is also a co-factor for making testosterone. Bananas, avocados, watermelon, eggs and raspberries are excellent sources.
3. Control cholesterol. Eat plenty of monounsaturated fats, as found in fish, yogurt, almonds, and olive oil.
4. Eat garlic. Some evidence suggests that allicin within garlic can help improve testosterone balance. Watch your breath, though.
5. Herbal remedies: Tongkat ali, Catuaba bark-Muira pauma, Mucuna pruriens, Tribulus, Yohimbine and Ginseng. You know my opinion on these so take at your own risk.

Medical Treatments that Improve Testosterone Balance

If all else fails, see a specialist, as there are excellent prescription medications that can boost your body’s testosterone production, which is not the same as testosterone replacement. Clomiphene citrate, tamoxifen and human chorionic gonadotropin (hCG) are not anabolic steroids, but nor are they FDA approved in the U.S. for this purpose. But they are drugs that either convince the brain to send more gas (luteinizing hormone, LH) to the testicles to make more of your own testosterone, or directly provide the LH to stimulate testicles to make it. Unlike anabolic steroids, they encourage bioidentical (read: “your own”) testosterone production and do not impair fertility or shrink testicles.

You should try to optimize testosterone balance naturally, as these behaviors are generally healthy and good for a long and happy life.

The beauty of a balsa wood board.

Up at dawn, and while waiting for a perfect, crumbling long board wave at Waikiki this past week, I recalled that Hawaiians live longer than the rest of Americans and wondered why. For some reason, life expectancy at birth in Hawaii is among the longest in the nation. Indeed, people born in Hawaii have a life expectancy of almost 81 years, at least three years longer than the US average. Why is this?

While watching rainbows appear and fade as early morning showers give way to the rising sun over Waikiki, I thought that it must be the fabulous and consistent climate. Then, as I saw surfers stream out to the break that I was tending before their workday started, I figured it must be that “island fitness” that pervades the tropics. Taking a large breath, I was reminded of the lack of air pollution and the sweet smell of jasmine, orchid and hibiscus flowers that blossom everywhere on the island. Could this be their secret?

A relaxing evening luau with soothing traditional aloha music and dancing accompanied by light, aromatic, almost Mediterranean dinner fare suggested that reducing stress and eating well and in moderation may also have something to do with it. Witnessing the deep respect held for family elders, for the community at large, and for the beauty and health of their island must also contribute in some way to longevity.

And then it hit me. Balance. The backbone of many older cultures is that they have found and maintain a seemingly harmonious balance as a civilization. They are aligned with others as individuals, with nature and with their place as a society on this good earth. The stress of extremes is present but not pervasive in such self-realized cultures and this is obvious in the genuinely large smiles that greet you at every corner of the island. So, let me propose a formula for staying healthy: realize that it is not life’s moments themselves that define you, but how you choose to live them.
