I had heard that sperm counts are dropping. What was news to me was that the decline is continuing, even accelerating, and also the concomitant drop in testosterone levels, starting even in utero. The bit about AGD was also pretty crazy — followed by the bit about men becoming less male . Some fear-mongering there no doubt, but a topic which in this era is more likely to be met with scoffs of “good riddance” rather t…

> followed by the bit about men becoming less male. This is pretty obvious without any research (papers). The difference between my generation and our children is already staggering in this regard. Not sure if that's just change in culture or physiological though; maybe a bit of both?

I resisted the urge to joke that this finally explains millenials, because it’s exactly that response which leads to the dismissive reactions this trend is being met with.

A couple days ago I shared a NYT article with my wife because it was such a strange window into evolving gender standards [1] and the next day a friend of hers shared another story which took it to a whole new level [2].

I could not help but tie it all together in my mind with TFA and dropping testosterone levels, but god help me for admitting it here.

In mammals generally testosterone levels and photoperiod are very closely linked. It would be surprising if our increasing use (abuse) or artificial light didn't sharply drop our testosterone levels.

Is it that artificial light drops T levels, or is it the lack of sleep? Though admittedly the former often leads to the latter.

I would love a reliable way to measure Birth Control and SSRIs in the water, and compare it to decades ago. I feel like there's a good chance these are "sleeper issues" affecting global health (in addition to the plastics as discussed).

Maybe somewhere there's an ice core that's saved representative water from the decades?

Regarding estrogens from BC in the water, some fish findings are quite suggestive:

studies with sample collection only after 1995—and the slope was even steeper. So that could not explain the decline we see after 1995.”

That’s about the time high speed pornography became available en masse. Coincidence?

Surprisingly, the only things I can find suggesting the existence of xenoandrogens seem to be attempts to sell me things.

I wonder why.
