Hims launches testosterone replacement therapy service for men

Hims, the publicly traded telehealth company, has launched a testosterone replacement therapy service for cisgender men, offering two injectable options and an oral pill after an at-home blood test. Peter Stahl, a urologist and senior VP of men's health at Hims, says the company aims to test as many men as possible for testosterone deficiency. Hims began in 2017 selling erectile dysfunction drugs and has since expanded into women's health, now serving 2.9 million customers.

JAMA study: Army's mandatory low-T screening could flag 25% of soldiers

A study published in JAMA found that mandatory testosterone screening ordered by Defense Secretary Pete Hegseth could flag up to a quarter of active-duty Army members as having low testosterone, even though the true prevalence of the condition is likely far lower. Researchers from Pennington Biomedical Research Center and the US Army Research Institute of Environmental Medicine analyzed blood samples from 479 male soldiers across five Army installations, collected between August 2024 and January 2026.

Men's biohacking culture pushes unproven testosterone and peptide regimens

Verge senior reviewer Victoria Song describes a growing online subculture of men sharing 'looksmaxxing' routines, including testosterone boosters, gray-market peptides, and drugs like Cialis taken off-label for longevity rather than their approved use. Figures like biohacker Bryan Johnson promote these regimens publicly, framing them as tools for physical optimization, appearance, or anti-aging rather than treating any diagnosed condition.

Pentagon's testosterone screening mandate for troops stalls in early rollout

Defense Secretary Pete Hegseth ordered testosterone deficiency screening for all service members aged 30 and older, but implementation of the program has reportedly gotten off to a slow and troubled start. Details on specific logistical or administrative obstacles causing the delay were not fully specified.

Pentagon pulls testosterone screening guidance days after publishing it

The Pentagon issued a clinical guidance document on September 2 implementing Defense Secretary Pete Hegseth's mandatory testosterone screening policy, then removed it the following day along with a related statement from spokesperson Sean Parnell. Officials told Ars Technica the document was temporarily rescinded to allow for updates, with an interim policy remaining active and a finalized version expected soon. The rescinded plan would have screened men 30 and older via questionnaire, potentially triggering blood tests and hormone therapy, while women faced similar screening for hormonal imbalances.
