A survey a few years ago explored people’s attitudes and expectations in regard to their fertility. There were a f
ew worrying misconceptions. Women knew their natural fertility declined with age, but thought that process commenced around 40, when it really begins around 30 to 32.
Only 3% of respondents felt that male factor infertility was important, and they were all women! In fact, 5% of males have varying degrees of sub-fertility. In many couples there are sub-fertility issues on both sides, compounding their chance of success together. Increasing female age is an ongoing compounder, complicating the initial cause of sub-fertility.
In more than 40% of couples requiring IVF, there is a male factor that needs treating. Micro-injection of the sperm has revolutionised the treatment of male sub-fertility, and is now a routine part of IVF treatment.
A semen analysis is an essential step in the initial work-up of a couple. That is not to say a sub-optimal count always predicts infertility. However, where there is failure to conceive after 18 months (12 months when the female is over 35), a sub-optimal sperm count and functional analysis is highly significant.
Why do so many men have impaired sperm function?
While the appropriate tests will identify genetic and known factors, the majority will be unknown.
What can be done to improve sperm function?
Certainly, lifestyle factors are important. Smoking is the main scourge. Whatever you do, don’t smoke, as Yul Brynner famously said on his deathbed.
Smoking affects the fertility and health of both men and women, and recent research finds that smoking could ultimately affect the health of your baby. While anti-oxidants may help, generally IVF makes the best use of the fewer sperm available.
Marijuana may upset sperm motility, as it is an endocannabinoid compound. Sperm is like a mini torpedo; the genes are packed tightly in the warhead. Marijuana can cause the sperm to fire its after-burner too soon, before reaching the egg.
Is male sub-fertility a new phenomenon? Are there environmental factors at work, affecting spermatogenesis? Unfortunately, we don’t have historical records to compare. I guess Henry VII must have had a normal sperm count. Pity he didn’t know that the lack of sons was his fault, not his six wives! “Off with her head!”
