Ejaculatory ducts
Ejaculatory Ducts
The Ejaculatory Ducts (pronunciation: ih-jak-yuh-luh-tawr-ee duhkts) are two small tubes that transport semen from the seminal vesicles where it is stored, to the prostate gland and into the urethra during ejaculation.
Etymology
The term "Ejaculatory Ducts" is derived from the Latin word "Ejaculatus", past participle of "Ejaculare" which means 'to throw out', and the Latin word "Ductus" which means 'a leading'. The term thus refers to the ducts that lead out the semen.
Anatomy
The Ejaculatory Ducts are approximately 2 cm in length and are formed by the union of the vas deferens and the duct of the seminal vesicle. They pass through the prostate gland and open into the urethra.
Function
The primary function of the Ejaculatory Ducts is to transport semen from the seminal vesicles and fluid from the prostate gland to the urethra, from where it is expelled from the body during ejaculation.
