In human anatomy, the perineum (Late Latin, from Greek περίνεος - perineos) is a region of the body including the perineal body and surrounding structures. There is some variability in how the boundaries are defined.
The perineum corresponds to the outlet of the pelvis.
A wide variety of slang terms are commonly used for this area of the human body, most commonly "gooch," "taint," and some others, but they generally refer to a smaller, less inclusive area -- just the surface skin region between the anus and the scrotum or vaginal opening.
The anogenital distance is a measure of the distance between the anus and the base of the penis or vagina. Studies show that the human perineum is twice as long in males as in females. Measuring the anogenital distance in neonatal humans has been suggested as a noninvasive method to determine male feminisation and thereby predict neonatal and adult reproductive disorders.
In Alfred Kinsey's 1967 report, he concluded that the perineum was one of the 6 key erogenous zones for males.
The layers and contents are as follows, from superficial to deep:
