Patient's question:
How many days after the menstrual period can one have sexual intercourse?Doctor's answer:
After cleaning, sexual activity can be resumed. During menstruation, sexual intercourse is prohibited because the endometrium forms wounds during this period, and the immune function 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 the development of endometriosis. Endometriosis may affect fertility, so sexual intercourse during menstruation should be avoided.
