Urogenital triangle explained

Urogenital triangle
Latin:	regio urogenitalis

The urogenital triangle is the anterior part of the perineum. In female mammals, it contains the vulva, while in male mammals, it contains the penis and scrotum.

Structure

The urogenital triangle is the area bound by a triangle with one vertex at the pubic symphysis and the two other vertices at the iliac tuberosities of the pelvic bone.

Components

As might be expected, the contents of the urogenital triangle differ greatly between the male and the female. Some of the components include:^[1]

• Posterior scrotal nerves / posterior labial nerves
• Urethra
