When faced with an abnormal prostate specific antigen (PSA) test, Thomas Seager, PhD decided to eschew the normal medical advice and opted to practice daily ice baths instead. Four months later he'd reduced his PSA from 5 to 1.8 ng/dL, indicating no elevated risk of prostate cancer.Along the way, he discovered that his total testosterone had shot up to 1180 ng/dL. In this lecture, Seager explains the mechanism of sex hormone synthesis in the mitochondria that likely explains his spectacular results, and answers questions from the CryoCon 2025 audience about deliberate cold exposure, prostate health, and the importance of total testosterone for mental health.In this powerful presentation from the CryoCon Convention 2025, Seager shares a personal and emotional story excerpted from his book "Uncommon Testosterone." He discusses how cold plunge therapy, specifically ice bath practices, can play a role in optimizing sexual health and overall well-being, touching on aspects of stress management.
