[edit] 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 ischiopubic rami of the pelvic bone.

[edit] Components

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

• Posterior scrotal nerves / Posterior labial nerves
• Urethra
• Bulbourethral gland / Bartholin's gland
• Muscles
  • Transversus perinei superficialis muscle
  • Ischiocavernosus muscle
  • Bulbospongiosus muscle
• Crus penis / Clitoral crura
• Bulb of penis / vestibular bulb
