Want to be Fertile? Be the Best Man You Can

We’ve known for a while now that, pound for pound, as a
group, infertile men aren’t as healthy as fertile men. It started with research
showing that infertile men have higher rates of cancer after infertility
than fertile men. Then, it became clear that infertile men harbor more disease
than fertile men. The latest data suggests that infertile men don’t
live as long
as fertile men and may carry more cardiovascular risk. So,
what’s a guy to do?

You Matter a Lot

Now, there’s evidence that it also works the other way
around: That is, by taking care of your health, your fertility may improve. In
a Japanese
study
of over 3,000 men evaluated for infertility over 20 years, semen
samples were compared before and after men were treated for 4 common
conditions: high blood pressure, high cholesterol, diabetes and uric acid
(gout) abnormalities. Here’s what they found.

Infertile men were more likely to have an underlying medical
condition than fertile men (22% vs. 9%). And that’s in Japan, where men are
typically thinner and fitter than men in the U.S.

Compared to otherwise healthy infertile men, men with these
conditions had lower sperm counts, lower sperm motility, lower testosterone
levels and higher chances of having no ejaculated sperm (azoospermia).

Azoospermic men were more likely to have a medical illness
than men with sperm in the ejaculate

Among infertile men whose medical illnesses were effectively
treated for 6 months, their semen quality improved significantly when compared
to untreated or poorly treated men.

The chance of semen improvement after treating medical
illnesses was in the same order of magnitude (2-3-fold) as that of repairing varicoceles,
an established surgical treatment for male infertility.

You Matter to Your Sperm

This is the first demonstration that treating medical
illnesses in infertile men can improve sperm production. And that is good news!
For lots of reasons: It begins to explain why a large chunk of otherwise
“healthy” men have low sperm counts. It also shows that, right alongside living
a longer life, fertility might be improved by staying healthy. Further, it
opens up a great path to treat male infertility without surgery or expensive
assisted reproduction technologies. I’m not sure who said this but it’s true:
“You can’t pour from an empty cup.” Please add “Get as healthy as possible” to
your New Year’s resolutions!
