The Ejaculatory ducts are part of the human male anatomy, which cause the reflex action of ejaculation. Each male has two of them.
They begin at the vas deferens, pass through the prostate, and empty into the urethra at the Colliculus seminalis. During ejaculation, semen passes through the ducts and exits the body via the penis.
