Patient's question:
NoDoctor's answer:
Hello, sexual activity during menstruation does not lead to pregnancy. Menstruation is a period when coitus is prohibited because during this time, the endometrium forms wounds, and the immune function of various systems declines, making it easier to develop 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 potentially resulting in endometriosis. Endometriosis can affect fertility, so coitus during menstruation should be avoided.
