GenX men have higher testosterone.
==Why do Gen Z and millennial men have lower testosterone levels?
Odds are your grandad had higher testosterone levels than you — but why?==
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.
But what is it about younger generations that has caused this trend?

The generational decline in testosterone
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.
What’s concerning is testosterone levels aren’t the only problem. Sperm counts are dropping significantly [8] and some reproductive disorders, like testicular cancer, are on the rise (9). Even men’s grip strength has declined [10]. So, what’s going on?
