Episode notes
TRT Popularity and Hype
- Testosterone replacement therapy (TRT) has surged in popularity, but is often based on anecdotal word of mouth rather than solid science.
- It is marketed as a cure-all for many symptoms including low energy and mood problems, but lacks broad evidence for these uses.
TRT Benefits for Low Testosterone
- Evidence shows TRT benefits those with clinically low testosterone by improving mood and libido.
- For men without low testosterone, benefits beyond muscle building are minimal or unclear.
TRT and Fertility Risk
- TRT causes the body to halt its own testosterone and sperm production through a feedback loop.
- This leads to potential infertility, a risk often overlooked, especially troubling for younger men who may want children.
