_Weakness and relaxation of the dartos muscle of the scrotum.
The scrotum consists of two layers, the integument and the dartos tunic.
In front, it is continuous with the dartos tunic of the scrotum; behind, with the subcutaneous areolar tissue surrounding the anus; and, on either side, with the same fascia on the inner sides of the thighs.
The body is ensheathed by fascia, which is continuous above with the fascia of Scarpa, and below with the dartos tunic of the scrotum and the fascia of Colles.
The Perineal Artery (a. perinei; superficial perineal artery) arises from the internal pudendal, in front of the preceding branches, and turns upward, crossing either over or under the Transversus perinæi superficialis, and runs forward, parallel to the pubic arch, in the interspace between the Bulbocavernosus and Ischiocavernosus, both of which it supplies, and finally divides into several posterior scrotal branches which are distributed to the skin and dartos tunic of the scrotum.
It is separated from the dartos tunic by loose areolar tissue.
Between the two there is a considerable quantity of areolar tissue, fat, and a tissue resembling the dartos tunic of the scrotum, besides vessels, nerves, and glands.
The dartos tunic is closely united to the skin externally, but connected with the subjacent parts by delicate areolar tissue, upon which it glides with the greatest facility.
The Dartos Tunic (tunica dartos) is a thin layer of non-striped muscular fibers, continuous, around the base of the scrotum, with the two layers of the superficial fascia of the groin and the perineum; it sends inward a septum, which divides the scrotal pouch into two cavities for the testes, and extends between the raphé and the under surface of the penis, as far as its root.
In the male, Campers fascia is continued over the penis and outer surface of the spermatic cord to the scrotum, where it helps to form the dartos.
