Men's testosterone and sperm count have been decreasing since the 1940's. If something that radical and widespread were affecting women's reproductive health we would hear about it every day. There would be marches and telethons. Congress and the UN would get involved.
As opposed to the sound of crickets, which is the current reaction to what is happening to male reproductive health.
Why does nobody know or care about this issue?
"The normal range of testosterone is reported as 350- 1200ng/dl. Studies in the 1940's showed the average testosterone level to be at 700 ng/dl, 300 ng/dl higher than for men today. In the past, a drop in testosterone levels to 250 ng/dl was rarely reported before men were 80 years of age. Yet today, it is not an uncommon value for middle aged men!"

"There have been a number of studies over the past 15-20 years which suggest that sperm counts in man are on the decline. Since these changes are recent and appear to have occurred internationally, it has been presumed that they reflect adverse effects of environmental or lifestyle factors on the male rather than, for example, genetic changes in susceptibility. If the decrease in sperm counts were to continue at the rate that it is then in a few years we will witness widespread male infertility. To date it remains unknown why this is happening and the available preventative measures, which can be taken to avoid a continuation of this trend, are not common knowledge."
