The perineal nerve is a nerve arising from the pudendal nerve that supplies the perineum.

Structure

The perineal nerve is the inferior and larger of the two terminal branches of the pudendal nerve, is situated below the internal pudendal artery.

It accompanies the perineal artery and divides into two branches:

• Superficial perineal nerves, becoming posterior scrotal nerves in men and Posterior labial nerves in women
• Deep branch of the perineal nerve (also known as "muscular")
