Seminal vesicle

Seminal Vesicle

The Seminal Vesicle (pronunciation: /ˈsɛmɪnəl ˈvɛsɪkəl/) is a pair of simple tubular glands posteroinferior to the urinary bladder of male individuals.

Etymology

The term "Seminal Vesicle" is derived from the Latin words "semen" meaning seed and "vesicula" meaning small bag.

Function

The main function of the Seminal Vesicle is to produce a significant proportion of the fluid that ultimately becomes semen. This fluid nourishes and protects sperm after it has left the penis during ejaculation.

Anatomy

The Seminal Vesicle is a pair of two convoluted pouch-like structures, located posterior to the base of the urinary bladder and anterior to the rectum. They are about 5 cm in length but their convoluted nature means that if uncoiled, they would measure approximately 30 cm.
