Pros/Cons oral TU (51:24-57:12)

*one of the things that the orals have transformed is the concept that you have to have a continually high level of testosterone to get the benefits and clearly that's not true and the safety profile seems to be improved by having levels that fluctuate some during the day returning to close to or even baseline




Synopsis


Dr. Morgentaler starts by sharing his pioneering journey with testosterone replacement therapy starting in the 1980s, challenging long-held beliefs that it increases prostate cancer risk. He highlights key studies to debunk myths about testosterone’s dangers and emphasizes the ability to improve patients’ quality of life. Further, he discusses modern treatment options and provides practical advice for safely initiating testosterone replacement therapy. Finally, he discusses its use in patients with a history of prostate cancer and emphasizes the importance of individualized treatment plans.

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
