Does masturbation increase my testosterone [level]?
Masturbation does not increase testosterone level. Teens going through puberty will see their levels increase between ages 13 and 18. Some even say 20 to 28 yr olds have buckets of it to spare because they’re horny all the time. So, age is more likely your answer. Oh, testosterone HRT (steroid) can increase it but those are available only through perscription.
