The ischiopubic ramus is a compound structure consisting of the following two structures:

• from the pubis, the inferior pubic ramus
• from the ischium, the inferior ramus of the ischium

It serves as part of the origin for the Obturator internus muscle.

It also marks a vertex of the anal triangle and the urogenital triangle.

The fascia of Colles is attached to its margin.
