In general, most women can return to their pre-pregnancy state after 42 days of cesarean section, and if the wound heals well and the dew is clean, they can resume sexual life appropriately. The time of intercourse after cesarean section is the same as that of natural delivery, mainly according to the recovery condition of the mother’s body. The uterus is not dilated during cesarean section, but there is a wound on the uterine wall. Under normal circumstances, the uterus can fully recover to its size before delivery in about 42 days after delivery, and the incision can fully heal. Therefore, it is more appropriate to resume sexual life after 42 days of cesarean delivery. Premature sexual life may lead to retrograde infection, endometritis and pelvic inflammatory disease, which will have certain influence on future pregnancy. In addition, women need to pay attention to their own care after cesarean section, regular rest and rest, light and easy to digest diet, less spicy and stimulating food, avoid staying up late, pay attention to local cleanliness and hygiene, etc.
