Dartos muscle

The dartos muscle is the thin rugated fascial muscle of the scrotum made of smooth muscle. Hence it is also referred to as dartos fascia or simply the dartos. It forms from the subcutaneous tissue of the scrotum and base of the penis and attaches to the scrotal skin and fibrous midline septum between the testes.

It is innervated by sympathetic fibers of the genital branch of the genitofemoral nerve and its action is to corruagate the scrotal skin, important in thermoregulation of the testes.
