Anatomical terminology

The perineal raphe is a visible line or ridge of tissue on the male human body that extends from the anus through the perineum.

This structure continues through the midline of the scrotum (scrotal raphe) and upwards through the posterior midline aspect of the penis (penile raphe). It also exists deeper through the scrotum where it called the scrotal septum. It is the result of a fetal developmental phenomenon whereby the scrotum and penis close toward the midline and fuse.[1]
