Ejaculatory duct

The Ejaculatory Duct is a significant part of the male reproductive system. It is formed by the union of the vas deferens and the seminal vesicle. The ejaculatory ducts are responsible for transporting sperm and seminal vesicle fluid to the urethra during ejaculation.

Anatomy

The ejaculatory ducts are approximately 2 cm in length and are located within the prostate gland. They begin at the union of the vas deferens and the seminal vesicles, and end in the prostatic portion of the urethra.

Function

The primary function of the ejaculatory ducts is to transport sperm and seminal vesicle fluid to the urethra during ejaculation. The seminal vesicle fluid, which makes up about 70% of the semen, provides nutrients for the sperm and promotes their motility.

Clinical Significance

Conditions that can affect the ejaculatory ducts include Ejaculatory Duct Obstruction (EDO), which can lead to male infertility. Symptoms of EDO can include painful ejaculation, lower abdominal pain, and decreased semen volume. Treatment options for EDO can include medication, surgery, or assisted reproductive technologies.
