Many years ago when I was young, I’ve seen posts on the internet on the subject of hairloss, saying that (excessive) masturbation/sex can contribute to hairloss.
I remember back then fully endorsing the opinion of those who claimed such a connection between ejaculation and hairloss has no scientific basis, is plain nonsense, and was invented by mean people trying to deprive balding guys from enjoyment.
Anyway, a week ago I tried to reevaluate my position concerning this issue. To my surprise, the claim of a connection between hairloss and ejaculation suddenly seemed to have a lot of sense.
I’ve been browsing Pubmed and saw articles showing that after ejaculation, the levels of Testosterone and DHT in the blood, go up. This of course makes sense, since after ejaculation it is logical that spermatogenesis should be increased, and so testosterone is needed.
It certainly makes sense that when testosterone levels are high in the blood, the levels will also go up in the hair follicles on the head, and there, some will be transferred to DHT by 5-alpha-reductase => contributing to hairloss.
I have to admit I’m not an endocrinologist. If any of you have links to papers or scientific basis that could explain why the above theory is flawed as a contributing factor for hairloss, I’ll be happy to read it.
