MeSH Ejaculatory+Ducts

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.

Ejaculatory duct obstruction is an acquired or congenital pathological condition in which one or both ejaculatory ducts are obstructed. In case both ejaculatory ducts are obstructed, this illness presents with the symptom of aspermia/azoospermia and male infertility. Surgery to correct Benign Prostatic Hyperplasia (BPH) may destroy these ducts resulting in retrograde ejaculation.

Ejaculatory ducts are part of the human male anatomy. They cause the reflex action of ejaculation. Each male has two of them. During ejaculation, semen moves through the ducts and leaves the body through the penis.
