Defense Secretary Pete Hegseth’s controversial plan to test service members’ testosterone levels may end up having an ironic side effect on male soldiers, two medical experts said in a new report.

Dr. Adrian Dobs, a professor of medicine and oncology at John Hopkins University School of Medicine explained the issue to The Intercept Friday.

“We’re sort of creating a dependency on testosterone,” Dobs said. “Men who take testosterone will have a reduction in their sperm counts.”

Last week, Hegseth announced a new policy that would see all U.S. service members over the age of 30 be tested annually for testosterone levels, boasting about his efforts to transform the Defense Department into the “High-T Department of War.”

The policy is already facing legal challenges, with a federal judge on Wednesday ordering the Trump administration to explain how the new testing policy squares with its existing ban on hormone treatment for transgender service members.

Per the policy, testosterone screening will be mandatory for all service members over 30, though service members under 30 may voluntarily get screened as well.

The concern among medical experts, such as Dr. Alvin Matsumoto, a professor emeritus at the University of Washington School of Medicine, is that mandatory screening may produce unreliable results given that a person’s testosterone levels can vary widely depending on a number of factors, including the time of day and recent meals.

“That creates a risk under a program that will routinely screen otherwise healthy troops and make testosterone therapy available to those subsequently diagnosed with a deficiency,” The Intercept’s report reads.

Furthermore, the policy would almost certainly result in some service members being given testosterone replacement therapy when not medically necessary.

“Here we have men who are in their prime of reproduction, and we’re causing a drop in their sperm counts when there really may not be sufficient benefit,” Dobs said.
