the pouch that contains the testes and their accessory organs. It is composed of skin, the tunica dartos, fascia, and the tunica vaginalis testis. Each testis is connected to a cremaster muscle descending from the abdominal wall. During cold weather these muscles draw the testes closer to the body to maintain their temperature, and in hot weather the reverse occurs; the scrotum usually follows this movement. adj., adj scro´tal.

scro′tal (skrōt′l) adj.


the pouch of skin containing the testes and parts of the spermatic cords. It is divided on the surface into two lateral parts by a ridge that continues ventrally to the undersurface of the penis and dorsally along the middle line of the perineum to the anus. In young, robust individuals the scrotum is short and corrugated and closely wraps the testes. In older people and debilitated individuals and in warm environments the scrotum becomes elongated and flaccid. The two layers of the scrotum are the skin and the dartos tunic. The skin is brownish and very thin, is usually wrinkled, and has thinly scattered kinky hairs. The dartos tunic is composed of a thin layer of unstriated muscular fibers around the base of the scrotum. The tunic projects an internal septum that divides the pouch into two cavities for the testes, extending between the scrotal ridge and the root of the penis. The scrotum is highly vascular and contains no fat. See also testis. scrotal, adj.

The skin and muscle sac containing the testicles and the start of the SPERMATIC CORD. The wrinkled appearance of the scrotal skin is due to the thin layer of DARTOS MUSCLE under the skin.



scrotal sac

a sac containing the TESTES of male mammals that is situatedoutside the posteriorly ventral part of the abdomen. The external location ensures that the testes are cooled to below body temperature (heat can adversely affect the development of sperm). In some organisms, such as bats, testes may lie protected inside the abdomen for much of the year, descending into the scrotum only during the breeding season.


The external pouch containing the male reproductive glands (testes) and part of the spermatic cord.


the pouch that contains the testes and their accessory organs. It is composed of skin, the dartos, fascia and the parietal layer of tunica vaginalis.
