Perineal Raphe

From Wikipedia, the free encyclopedia


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.

A raphe is sometimes described as a suture line, and indeed when you look at the underside of the male genitals, it appears that two sides have been sewn together.  Involving the scrotum especially, it seems to extend all the way to the base of the glans corona where the frenulum appears.

Here are some more examples:


And finally note how the treasure trail here appears to extend the line up to the navel:

I have always thought that line was very interesting. How in some guys it was very light, and barely there, and in others quite pronounced. The more pronounced lines seem also to be more sensitive to touch.

Thanks for the interesting post!

Thanks Biki for your response.

Actually, I think it is more pronounced in boys and young men, sort of fading to a dark brown line in older men. As a boy, I remember my raphe as being very distinct and raised all the way back to my anus and I could not understand why I had that pronounced line.

Of course, it lies within a very erogenous zone and since the whole area is very sensitive to us males, we enjoy stimulation in the area.

I have wondered if women have anything similar, especially between the labia and the anus.
