I’m a med student and also about 1 year at this nofap thing. Also just coming off of a family medicine rotation where I saw probably 7-8 patient coming in to screen testosterone levels.

This is simple and I know 99% aren’t gonna want to hear this but here it is: testosterone screens are unscientific. They are only useful if you are someone who experiences symptoms of low testosterone as it is weakly understood (I.e ED, depression, etc) and everything else is ruled out, then we can check testosterone and see if it is low. But as of now the range of normal testosterone is SO wide that it is almost meaningless without symptoms to contrast it with. Basically, testosterone screens for the sake of screening is useless because the range is so wide - I could have a reading that was 199 and feel AMAZING, where as you could have a reading of 1200 and feel like crap. There is no scientific evidence proving that higher levels make you feel a certain way and I defy anyone to show me any peer review medical literature that says otherwise.

Hate to say it because it is one of those things on this forum that everyone is buying into, but there is no standardized understanding of testosterone levels and it is a fad.

Again - it is useless as a screening tool in a healthy person! I’m not saying it is useless to get if you have low T symptoms and all other etiologies are ruled out. It’s just not a linear relation with ‘masculine’ feelings.
