Global 54% drop in testosterone over five decades, study finds
TL;DR Summary
A large, multi-country meta-analysis of 118,593 men from 1972–2019 found total testosterone declined by 54% worldwide, averaging more than 1% per year and accelerating after 2000, beyond age-related declines; the researchers note obesity and metabolic syndrome could explain part of the drop and highlight potential roles for environmental chemicals, lifestyle factors, and other health trends, with implications for overall male hormonal health and fertility.
