What are the Seminal Vesicles?
The primary purpose of the vesicles is to supply a viscous, alkaline secretion that forms as part of the seminal fluid. Although the sperm do not travel through the seminal vesicles, the vesicles do play a vital role in sperm survival. The fluid from the seminal vesicles, usually contribute more than half of the seminal volume. Their secretions are particularly rich in a sugar (called fructose), which is an essential energy source for the sperms metabolism, as well as enhances sperms motility. The vesicles also produce a substance that causes the semen to clot (become sticky or jelly-like) after ejaculation, thought useful in reproduction for keeping the semen at the neck of a woman’s womb. In regard to appearance, the seminal vesicles are two pouches located behind the bladder above the prostate gland that are about 5 to 7cms (2 to 2.75 inches) in length by about 2 to 3 cm wide. In each vesicle is a tubule that is about 15cm long that is coiled; surrounding this is connective tissue m
