see testosterone decline:
"For decades, testosterone levels have been declining. Your grandad may not have been quite as swift with Excel, but he probably one-upped you where T levels are concerned.
It’s normal for testosterone levels to decline as you get older, but for some reason, there’s been a population-level drop with each generation, at least since the 70s [1–4]. This means, on average, Gen Zers and millennials have significantly lower testosterone levels compared to their predecessors."

Are these measurements of testosterone credible?
