What is "ejaculatory duct"

n. (context anatomy English) Either of a pair of ducts through which semen passes, each of which is formed by the merging of the vas deferens and the duct of the seminal vesicle.

n. a part of the seminal duct formed by the duct from the seminal vesicle and the vas deferens; passes through the prostate gland

The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy. Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra at the Colliculus seminalis. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the tip of the penis.
