The male genitals consist of the penis, scrotum, and the two testes, which are suspended in the scrotum. Above and behind each testis is an epididymis, a coiled tube that leads to another tube called the vas deferens. The upper end of each vas deferens is joined by a duct draining from a gland called the seminal vesicle. This duct and a vas deferens together form an ejaculatory duct. The two ejaculatory ducts then join the urethra where it is surrounded by the prostate gland, and the urethra passes through the penis to the outside.
