Perineal raphe
Template:Infobox Anatomy Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
The perineal raphe extends from the anus, through the mid-line of the scrotum (scrotal raphe) and upwards through the posterior mid-line aspect of the penis (penile raphe).
It is observed as a noticeable line.
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.
The resulting ridge of tissue is evident as the perineal raphe.
