The seminal vesicles are a pair of glands posterinferior to the Urinary Bladder of males. They secrete a significant proportion of the fluid that ultimately becomes Semen . About 70% of the seminal fluid in humans originates from the seminal vesicles. They are approximately 15 cm in length.

Seminal vesicle secretions contain Protein s, Enzyme s, Fructose , Phosphorylcholine and Prostaglandin s.

The duct of the seminal vesicle enters the Prostate Gland along with the Ductus Deferens (the tube coming from the Testis ). They join to form the Ejaculatory Duct .

Histologically , the seminal vesicles are defined by their tortuous pathways, false Lumen s, pseudo-stratified columnar Epithelium and cuboidal Cell s along the basal layer.
