Two layers of fascia envelop the pudendal nerve canal: a cadaver study
The pudendal nerve travels within the fascia derived from the sacrotuberous ligament and does not pass through the fascia of the obturator internus. The proper fascia of the obturator internus muscle is located relatively close to the muscle, and the obturator internus nerve courses between the obturator internus muscle and its own fascia. These findings describe the anatomy of the pudendal canal and may provide a foundation for future surgical investigation.
