Explain by medical theory!did excessive ejaculation for 2yr like 2to3 time a day in past increase my testosterone levels cause baldness at age 20?

DHT causes baldness: So let's try again. Masturbation does not increase testosterone. Masturbation does not cause baldness. Genetics is main reason for male pattern baldness although acute illness, infection, etc can cause thinning hair & patchy loss. Dihydrotestosterone (converted from t) is partially responsible for male pattern baldness. Check out http://en.Wikipedia.Org/wiki/androgenic_alopecia for more info.
