Do testosterone levels really drop automatically with age? Are men becoming increasingly infertile? And when is testosterone therapy actually worthwhile?
Dr. Armin Soave, head of andrology at the University Medical Center Hamburg-Eppendorf and president of the German Society for Andrology, speaks with Dr. Jonathan Apasu about the most important questions surrounding male hormonal health, fertility, and prevention.
In this episode, he explains why it is not age, but above all overall health, that determines testosterone levels, how obesity and lifestyle affect hormone production, and why the growing trend of testosterone optimization should also be viewed with a critical eye.
