The Pentagon removed guidance for its new mandatory testosterone screening program from its website on Thursday, a day after it was initially posted—as the controversial program, and Defense Secretary Pete Hegseth’s rhetoric surrounding it, has raised questions about its medical efficacy and gender politics in the military.

The Defense Health Agency webpage where the guidance was published Wednesday showed a “page not found” message on Thursday that said it’s either been moved or removed.

A U.S. official told Reuters the guidance remains in effect, but has been “temporarily rescinded to allow for updates.”

The guidance said male U.S. service members over the age of 30 would first be screened through a mandatory questionnaire to determine if a blood test is needed, while younger men will be tested if warning signs are identified by a doctor, according to Reuters.

Women would be screened for signs of hormonal dysregulation, such as fatigue and changes in menstrual patterns, that could indicate an energy deficiency condition known as Relative Energy Deficiency in Sport (RED-S).

According to the retracted guidance, female service members over the age of 35 who report clinically significant symptoms of perimenopause or menopause would be assessed to determine if the symptoms impact their duties or quality of life, the Military Times reported.

The guidance also suggested prescribing off-label testosterone to women in some circumstances, including postmenopausal women with unusually low sex drive, according to Reuters.

Experts have expressed concerns about the reliability of tests measuring testosterone level and the possibility for overtreatment. Dr. Kevin McVary, a urologist on the medical advisory board for the telehealth platform Rugiet, told Reuters the evidence supporting testosterone replacement therapy “is not concrete, and it comes from patients who were treated because they were symptomatic.” He said treating asymptomatic patients could lead to overtreatment. The American Urological Association and the Endocrine Society recommend testosterone supplementation only for patients with confirmed deficiency and symptoms such as reduced sex drive, erectile dysfunction, fatigue, decreased muscle mass and low bone density, according to Reuters.

Hegseth announced the new screening policy in a July video captioned “The High-T Department of War.” Hegseth said it would be optional for male soldiers with low testosterone to receive hormone-replacement therapy. The program, he said, is “about restoring and optimizing your natural capabilities, protecting your longevity, ensuring you have the biological foundation required to sustain the fight” and “keeping you on the leading edge of lethality.” The policy adds to the culture of masculinity Hegseth has sought to foster in the military. He has said repeatedly he doesn’t believe women should serve in active duty combat roles and he has supported the Trump administration’s ban on transgender troops.
