Patient's question:
What happens if you have sex during your period?Doctor's answer:
Menstruation is prohibited during sexual intercourse because during menstruation, the endometrium forms wounds, and the immunity of various systems declines, making it easy to cause inflammatory infections, such as endometritis, pelvic inflammatory disease, and adnexitis. Additionally, during female sexual arousal, uterine contractions may cause menstrual blood to flow back into the pelvic cavity, leading to endometrial implantation and resulting in endometriosis. Endometriosis may potentially affect fertility.
