In female, the perineum is the region between the anus and the vulva (of the vagina). In male, it is the region between the anus and the scrotum. In human anatomy, it is diamond-shaped and an erogenous zone in both males and females.1 In females, the skin on this region may be lacerated naturally during childbirth and it is referred to as perineal tear. Episiotomy is one that is intentionally cut by surgery to facilitate and aid a difficult delivery.
Word origin: Ancient Greek perínaion, períneos, from perí, (“around”) + inéō (“I empty, evacuate”)
