What are the harms of having sex during menstruation for men?

Having sex during menstruation can also pose certain risks to men. During a woman's period, the uterine lining sheds and the cervix is open, making it easier for bacteria to enter the body during intercourse and increasing the risk of infection. These bacteria may enter the male urethra through the genitalia, potentially causing conditions such as urethritis or prostatitis. Sexual activity during menstruation may also trigger uterine contractions, worsening menstrual cramps, and even leading to serious conditions like endometriosis. Therefore, to protect both their own and their partner’s health, men should avoid intercourse during their partner’s menstrual period. Additionally, both partners should maintain good hygiene practices to reduce the risk of infection. If any discomfort or symptoms occur, prompt medical evaluation and treatment are recommended.
