Uberon definition : The Ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy,
about 2 cm in length. 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 empty into
the urethra at the Colliculus seminalis. During ejaculation, semen passes through
the ducts and exits the body via the penis[WP,unvetted].;
