Editing Male genitals (section)

== '''Scrotum''' ==

* Pouch of skin containing the     testes and spermatic cords
* Superficial fascia is     continuous with superficial abdominal fascia (Colles fascia), so blood can     drain down into scrotum
** Superficial fascia contains      muscle fibres - dartos - but no fat
** Dartos innervated by SNS      fibres along with genital branch of genitofemoral nerve
* Scrotal septum divides     scrotum down the midline - midline raphe is the surface marking
* Blood supply
** Superficial and deep      external pudendal arteries
** Posteriorly some branches      from internal pudendal
* Innervation
** Ilioinguinal nerve to      anterior third of scrotal skin
** Posterior scrotal branches      of the perineal nerves (S2-4) and the perineal branch of the posterior      cutaneous nerve of the thigh to the posterior two-thirds of the scrotal      skin
* Lymphatics
** To superficial inguinal      nodes
