Men’s average testosterone levels have halved in last 50 years, say scientists

Scientists have revealed a significant decline in men's average testosterone levels over the past half-century, dropping by 54% between 1972 and 2019. This alarming trend, partly linked to rising obesity and diabetes rates, has prompted warnings about a potential major crisis in male reproductive health. As testosterone plays a crucial role in fertility, muscle mass, and overall health, this decline could have broader implications for men's health and future generations. Researchers are urging a deeper look into lifestyle factors to mitigate this troubling trend.
