Perineal hernia is a hernia involving the perineum (pelvic floor). The labia majora extend from the mons pubis to the perineum. The pelvic floor separates the pelvic cavity above from the perineal region (including perineum) below. The perineal membrane is an anatomical term for a fibrous membrane in the perineum. The labia minora, clitoris, perineum and mons are less commonly involved. It is located behind the perineum which is located behind the vagina or scrotum. The scrotum is located high in the perineum with the testicles in separate sacs. This allows quick pain relief to the perineum, vulva, and vagina. Bidets are primarily used to wash and clean the genitalia, perineum, inner buttocks, and anus. The area between the vagina and the anus is known as the clinical perineum. The main symptoms are itching in and around the anus and perineum. Later it descends down and supplies branches to abdomen, pelvis, perineum and the lower limbs. The pudendal nerve is the main nerve of the perineum. The perineum and cervix are further flattened and the head may be felt vaginally. The urogenital triangle is the anterior part of the perineum.
