The perineal raphe is a visible line or ridge of tissue on the human body that extends from the anus through the perineum.
In men, this raphe continues through the midline of the scrotum (scrotal raphe) and upwards through the posterior midline aspect of the penis (penile raphe). It is the result of a fetal developmental phenomenon whereby the scrotum (the developmental equivalent of the labia in females) and penis close toward the midline and fuse.
