The scrotum is a muscle-cutaneous sac containing the testes, epididymis and first portion of the vas deferens.

Each set of these organs (right and left) occupies a completely separate compartment, as the scrotum is subdivided into two stores by a medial sagittal partition called the scrotum septum.

Superficially this septum corresponds to a cutaneous raphe (median rough line), very evident.

The scrotum consists of different layers of tissue that stratify from the periphery to the depth in the following seven planes.

Cutis: It is the thin, wrinkled skin that has transverse folds and sparse hair. In the midline we find the scrotum rafe.

Dartos tunic: The dartos tunic is a true cutaneous muscle, formed by smooth muscle fibers.

Subcutaneous screen: consists of loose connective tissue.

External spermatic fasciaIt is a conjunctival lamina that comes from the two enveloping fasciae of the external oblique muscle of the abdomen, which descends from the superficial inguinal annulus to enter the constitution of the scrotum.

Cremastic Fascia: This plane is represented by a thin conjunctival lamina that holds numerous bundles of striated muscle fibers of vertical direction.

Taken together, these muscle fibers form the craster muscle and derive from the internal oblique muscle fibers of the abdomen.

Internal spermatic fascia: conjunctiva blade that derives from the transverse fascia.

Vaginal tunic: Serous whose parietal leaflet represents the deepest layer of the scrotum, while the visceral leaflet surrounds the testis, epididymis and beginning of the vas deferens.
