Anatomical Information about Perineum

The part of the body between the anus and the genitals, or sex organs. In males, the perineum is the area between the anus and the scrotum, the external pouch of skin that holds the testicles.

Why is the perineum important?

The perineum is important because it contains blood vessels and nerves that supply the urinary tract and genitals with blood and nerve signals. The perineum lies just below a sheet of muscles called the pelvic floor muscles. Pelvic floor muscles support the bladder and bowel.
