scroto-, scrot- +

(Latin: the pouch that holds the testes; a purse; probably a variant of scortum, "a skin, hide"; or of scrautum, "a leather bag for holding arrows"; akin to scrupus, "a sharp stone")

scrotum (s), scrota (pl)
1. The pouch found in most male mammals that contains the testicles and part of the spermatic cord.

It allows sperm to develop at a temperature lower than that of the body.

It is composed of skin, the dartos [muscular, contractile tissue under the skin], the spermatic [semen or sperm], cremasteric [muscles suspending and enveloping the testicles and spermatic cord], infundibuliform fasciae [membranous layer encircling the spermatic cord with a sheath of tissue], and the tunica vaginalis [serous (serum) membrane surrounding the front and sides of the testicle].
