The pudendal canal (also called Alcock's canal) is an anatomical structure in the pelvis through which the internal pudendal artery, internal pudendal veins, and the pudendal nerve pass.

Structure

The pudendal canal is formed by the obturator internus fascia.

It encloses the following:

• Internal pudendal artery
• Internal pudendal veins
• Pudendal nerve

These vessels and nerve cross the pelvic surface of the obturator internus.
