How low is too low when it comes to testosterone levels? When Defense Secretary Pete Hegseth announced in July 2026 that U.S. service members ages 30 and older will have their testosterone tested every year, neither he nor the Pentagon specified what level of the hormone would be considered “low” enough to require treatment – a telling omission, since where “low” begins depends on the lab conducting the test and the guidelines your doctor follows.
The announcement lands amid a national testosterone craze: Prescriptions have climbed to nearly 12 million in 2025, up 154% since 2020, and fastest among men in their late 30s and 40s. Online clinics that sell testosterone as a lifestyle upgrade have largely driven this rise in prescriptions.
