https://www.medichecks.com/blogs/testosterone/why-do-gen-z-and-millennial-men-have-lower-testosterone#:~:text=It's normal for testosterone levels,levels compared to their predecessors.

The average testosterone level of a 60-year-old man in 1987 was around 17.5nmol/L, according to a 2007 study in Massachusetts [5]. Compare that to a 60-year-old man in 2002 — his testosterone level was closer to 15nmol/L. 

Based on this, average testosterone levels in men are declining by 1% every year, give or take.  

Research carried out on Finnish and Danish populations has shown the same trend [1,6]. And even more recently, a large-scale study of Israeli men has shown how average testosterone levels have dropped between 2006 and 2019 [7] — by over 10% across almost every age category.  

Of course, we can’t know for certain that 60-year-old millennials and Gen Zers will have lower testosterone levels, at least not for a few decades, but it’s looking very likely.

The reasons he gives are obesity and toxins. I think this will start the trend of people using modern medicine to give their sons advantages. If having a micropeen is a societal thing, doing something about it will become normalized.

China has so much pollution and a large population so they have to be competitive and combat the toxins in the environment as much as they can. A lot of parents try to buy their sons illegal growth hormones to make them taller.

Personally, I think the media will push similar things in the West when they get sick of the white incel epidemic. I already saw a few articles about white guys getting height surgery.
