Many pregnant women who have thick pubic hair on their vulva need to have their pubic hair shaved when they are ready to give birth with their uterus fully opened on the delivery bed. The first purpose of shaving the pubic area is to maintain a clear view, because especially in first-time mothers, many will have perineal lacerations during the birth of the first child, and if there is pubic hair, it affects the view, affects the operation, and is not conducive to stopping the bleeding when the midwife sutures. The second purpose is to avoid infection and keep the vulva clean, because if the hair is dense, then it is easy for bacteria to breed, so it is important to keep the vulva clean. But pregnant women whose perineal pubic hair is not dense, some of them do not need to mention the pubic hair.
