Structure/Morphology

The dartos fascia of scrotum is a motile sheath of fibrous connective tissue that is continuous with the superficial fascia of the penis. It contains smooth muscle, which is responsible for giving the scrotum a wrinkled appearance.

Anatomical Relations

The dartos fascia of the scrotum lies superficial to the external spermatic fascia of the scrotum.

Function

The dartos fascia of scrotum is responsible for temperature control in the testes. The contraction of the smooth muscle brings the scrotum and testes closer to the body (increasing temperature). Relaxation of the muscle allows the scrotum and testes to move further from the body (decreasing temperature).

Arterial Supply

The dartos fascia is supplied by the scrotal arteries, which are branches from the internal pudendal arteries and the cremasteric arteries, which are branches from the inferior epigastric arteries.

Venous Drainage

The dartos fascia is drained by the scrotal veins, which drain into the internal pudendal veins and the cremasteric veins, which drain into the inferior epigastric veins.

Innervation

The dartos fascia receives sympathetic innervation from the genital branch of the genitofemoral nerve.

Lymphatic Drainage

The lymph of the dartos fascia is drained into the superficial inguinal lymph nodes.
