Patient's question:
Female, 20sDoctor's answer:
Having sex during menstruation will not result in pregnancy, but it is forbidden to have sexual intercourse during this period. This is because the endometrium forms wounds during menstruation, and the immune systems of various systems decline, making it easy to lead to 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 the implantation of endometrium and the development of endometriosis. Endometriosis may affect fertility, so it is necessary to avoid sexual intercourse during menstruation.
