I'm playing with fire going against the narrative, but I'll just say this:
You should be highly skeptical of any claims of drastic variance in human biology over short time periods.
Men's average testosterone levels have halved in last 50 years

#22> Obesity was also not controlled for, which is known to be strongly correlated with low testosterone.
Testosterone is directly causally inverse to bodyfat in men (once above some very low baseline)
Fat directly converts testosterone to Estrogen via a process called aromatization.
Personally my Testosterone close to doubled when going from 25% bodyfat to 13%. I get blood tests regularly and can see the levels fluctuate pretty closely with fat levels

#23It's just our shitty food system and sedentary lifestyle but everyone is projecting their weird hangups on it

#24“Obesity and diabetes could easily account for all of this,”
Wither Ozempic? I've seen several friends and family members use it to great effect and thought it might sweep the nation. But I imagine most of the same barriers that keep people from eating better or moving more are also in play when trying to engage with any new habit.

Really makes the study completely pointless when the last 50 years has also seen the rise of the global obesity epidemic.

#26High cortisol lowers testosterone - some adaptogens like ashwagandha modulate the HPA axis and lower cortisol release, increasing T levels

#27I'm old, but I get this subjective read: of my friends and even family who had sons, they seemed smaller and less bold than we were 50 years ago.
less bold? what do you mean?

That is not how biology works
While I mostly agree with your statement there's evidence that testosterone is linked to social status and mental well being.
A 50% drop most likely has a multifactorial explanation, being told that some traditional male traits are bad (and thus lower well being or social status) or medicated away (see e.g the rise in ADHD and Autism diagnosis) might have some effect.
I'm not nearly knowledgable enough to give any reasonable estimate but it would not surprise me if it was higher than 0%.

Or the negatives (toxic femininity)
