Description:Alternative names Testicles; testis singular Coloured scanning electron micrograph of sperm cells that are developing inside a seminiferous tubule. The developing heads of the sperm cells are embedded in a layer of Sertoli cells red that nourish the developing sperm. The testes, also known as testicles or male gonads, lie behind the penis in a pouch of skin called the scrotum. The testes move freely in the scrotum but each testis is attached to the body wall by a thin cord called the spermatic cord, which passes through a cavity in the pelvis and into the abdomen. The cord contains the nerves and blood vessels for the testes as well as the vas deferens, which carries the sperm from the testes into the urethra; the urethra is the passageway for sperm to the outside of the body at ejaculation.
