Whether or not masturbation once a day can lead to infertility needs to be judged by the physical symptoms manifested. If after masturbation, it does not affect the next erection and there is no physical discomfort, it means that it is not excessive and that conscious moderation to reduce the frequency of masturbation is sufficient without excessive worry. However, if after masturbation, physical symptoms such as erectile dysfunction, premature ejaculation, mental weakness, physical fatigue and weak ejaculation occur, it generally means that masturbation is excessive and can cause serious urogenital discomfort and lead to infertility. In this case, it is recommended to reduce the number of masturbation or temporarily quit masturbation, pay attention to rest and nutritional supplements, adhere to sports and exercise, and then masturbate moderately after the body recovers or after medical treatment.
