Masturbation when you have your period may affect your fertility. There are various ways to masturbate, and different masturbation methods and frequencies have different effects on the body. During menstruation, masturbation in either way may have an effect on the body, causing gynecological inflammation such as vaginitis and cervicitis, and can also cause endometriosis. If the diseases caused are not treated in time, they can affect fertility and lead to infertility. Pay attention to the hygiene of the perineum when you have your period and do not touch the vagina with your hands, especially the inside of the vagina, which can easily cause gynecological infections. Normally, if abnormal symptoms appear after masturbation, you need to take the time to go to the hospital for treatment.
