Masturbation and testoserone
The short answer to this question? Masturbation, whether solo or with a partner, can have a variety of effects — although mostly short term — on T levels. T levels naturally rise during masturbation and sex, and fall to normal levels after orgasm. One older study found some evidence that abstaining from masturbation and sexual activity for three months or more may reduce T levels until sexual activity is resumed. But this study was conducted on people with erectile dysfunction ED.
