月经完后几天可以同房

Some people believe that women are in a “safe period” immediately after menstruation begins, and therefore cannot become pregnant during intercourse. So, how many days after menstruation ends is it safe to resume sexual activity?

How many days after menstruation ends is it safe to resume sexual activity?

Generally, it is advisable to wait until three days after menstruation has completely ended before resuming intercourse—provided there is no post-menstrual bleeding. By this time, the endometrium has fully shed, and the cervix has closed. Consequently, the risk of infection during intercourse is relatively low. Additionally, for women with longer menstrual cycles, ovarian follicles are still in the early developmental stage during this period, further reducing the likelihood of conception.

Sexual intercourse is not recommended immediately upon completion of menstruation, as it may trigger vaginal bleeding. During the late phase of menstruation, small blood vessels and glandular ducts on the uterine cavity surface remain ruptured; minor bleeding may occur, and although new endometrial tissue begins to regenerate, it remains uncovered by epithelium. While hemostasis has occurred, complete tissue repair and regeneration have not yet been achieved. Thus, mechanical stimulation from intercourse may damage these incompletely healed sites, leading to bleeding.

Maintaining sexual health and practicing protective measures not only prevents unintended pregnancy but also helps guard against infections and bacterial diseases. If pregnancy is not desired, using condoms during intercourse is strongly recommended. Additionally, attention to personal hygiene—including keeping the genital area clean and dry—is essential.
