Urogenital triangle

The urogenital triangle forms the anterior half of the diamond-shaped perineum. The triangle's corners are defined by the pubis symphysis anteriorly and the ischial tuberosities anterolaterally. The anterolateral borders are the ischiopubic rami and the posterior border is the transverse perineal muscles.

It contains the penis and scrotum in males and mons pubis, labia majora and minora, clitoris and vaginal and urethral orifices in females.

The perineal membrane, a thin sheet of fascia, covers the urogenital diaphragm inferiorly which divides the urogenital triangle into the deep perineal pouch and the superficial perineal pouch.
