fructose and other enzymes that help the sperm to survive to
facilitate successful fertilization. During the process of
ejaculation, the semen is ejaculated from the seminal vesicle in
the pelvis, which is where it is produced. Composition of semen
Semen passes through the ejaculatory ducts and mixes with fluids
from the seminal vesicles, the prostrate, and the bulbourethral
glands. The seminal vesicles produce a viscous, fructose-rich
fluid. This forms around 65-70% of the semen base. The white

containing enzymes, citric acid, lipids, and acid phosphatase.
This forms around 25-30% of the semen base. At each ejaculation
