Information about Ejaculatory Duct

Male Anatomy
Vesiculæ seminales and ampullæ of ductus deferentes, seen from the front. The anterior walls of the left ampulla, left seminal vesicle, and prostatic urethra have been cut away.
Latinductus ejaculatorii
subject #261 1247
MeSH Ejaculatory+Ducts
The Ejaculatory ducts 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.

Surgery to correct Benign Prostatic Hyperplasia (BPH) may destroy these ducts resulting inretrograde ejaculation.

The seminal vesicles are a pair of simple tubular glands posteroinferior to the urinary bladder of males.

Anatomy

They are approximately 5 cm in length, though the full length of the gland is approximately 10 cm and curled up inside of the structure.

In anatomy, the urethra is a tube which connects the urinary bladder to the outside of the body. The urethra has an excretory function in both genders to pass urine to the outside, and also a reproductive function in the male, as a passage for sperm.

Semen is an organic fluid (also known as seminal fluid) that usually contains spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals for fertilization of female ova. The process of discharge is called ejaculation.

In males, retrograde ejaculation occurs when the fluid to be ejaculated, which would normally exit via the urethra, is redirected towards the urinary bladder. Normally the sphincter of the bladder contracts and the sperm goes to the urethra towards the area of least pressure.
