Testosterone and fertility: the trade-off men aren't told about

The rising popularity of testosterone supplementation, driven by trends in fitness culture, social media, and political discourse, has prompted medical concern regarding its impact on male fertility. Recent discussions include proposals by U.S. Defense Secretary Pete Hegseth to implement testosterone screening for military personnel.

Medical experts highlight a significant trade-off associated with exogenous testosterone use: while supplements may increase hormone levels, they can simultaneously suppress the body's natural production of testosterone and sperm. This physiological response poses a risk of infertility for men who are not fully informed of the long-term reproductive consequences of supplementation.
