The ejaculatory ducts (ductus ejaculatorii) are paired structures in the male reproductive system.[1] Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle.[2] They pass through the prostate, and open into the urethra above the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.[3]
