We have all heard of it, we know that it’s linked to building muscle and athletic performance and that people sometimes supplement it; but what does it really do? Where does it come from? What other effects does it have? This video is designed for folks without a major scientific background who want to learn more about testosterone. One quick point before I get started. Although testosterone does have effects on the human body from conception all the way through puberty, I’m going to focus specifically on the effects of testosterone in adults (post-puberty) in this video. Testosterone is an androgenous steroid hormone. Anabolic (promote building) Promote Muscle mass, strength Body composition, decrease body fat Increase bone Density Increase Red Blood Cell production (via kidneys) Prostate: Testosterone can be converted to dihydrotestosterone (DHT) which promotes prostate growth (and why our prostates tend to get larger as we age) Androgenic (Male function) Aids in erectile function Libido and sex drive Normal sperm development: Sustains sperm development and fertility Estradiol: In adipose tissue, testosterone is converted to estradiol which is the primary female sex hormone. Men do require some estradiol for healthy function, however obese men can significantly increase their estradiol levels (which can cause development of female features and also suppress testosterone synthesis). Psych: Helps reduce risk of depression, improves mood May stave off dementia, improve cognitive function
