Defense Secretary Pete Hegseth announced a new testosterone-deficiency screening program for service members, but endocrinologist and former military doctor Dr. Karl Nadolsky says the science doesn’t support universal testing in people without symptoms. In this episode, we break down who should be evaluated, why obesity/sleep apnea and certain injuries or medications can lower testosterone, and what risks come with unnecessary testosterone replacement therapy (including infertility).

00:00 intro
00:01:00 Meet Dr. Karl Nadolsky (endocrinologist, former military physician)
00:02:02 Full clip: Pete Hegseth explains annual testing for 30+; optional under 30
00:04:31 What testosterone does/doesn’t do for performance; who truly benefits from TRT
00:05:30 How common is “true” hypogonadism vs functional low T (obesity/sleep apnea/diabetes)
00:06:48 Why widespread screening isn’t recommended; lack of evidence for better outcomes
00:08:44 Medication/injury causes: opioids, TBI, blast/testicular trauma; why targeted screening fits
00:11:59 Main risks: false positives, wrong timing/conditions for labs, unnecessary anxiety/cost
00:13:38 Proper workup: treat root causes first; don’t miss pituitary disease or sleep apnea
00:14:06 TRT tradeoffs: fertility suppression, potential long-term dependence; steroid/male-clinic pitfalls
00:16:16 Women and testosterone: testing mostly for high levels; limited menopause libido use
00:19:29 Military endocrinology + why expert input/task force matters for policy
00:22:15 Practical alternative: checkbox-based risk triggers and symptom screening at annual physicals
00:23:34 Closing: keep politics out; follow data and build evidence-based protocols
