Frequent masturbation can lead to a decrease in semen volume or even no semen ejaculation during intercourse, which can be restored through abstinence from masturbation plus lifestyle modification. Although the human testicles produce sperm every day and make semen every day, each ejaculation will consume a portion of the semen, if masturbation is too frequent, a few times a day or five or six times a week or more ejaculate more than the amount of semen produced, the coitus may not be able to ejaculate the semen situation. By abstaining from masturbation and controlling it below two times a week, as well as eating more foods rich in zinc and selenium as well as vitamin E and vitamin C, and avoiding staying up late at night, you can generally return to normal; if you still can’t ejaculate, you need to go to the hospital for examination and diagnosis, to rule out dyspareunia, and then be given treatment.
