Semen is a complex biological fluid composed of sperm cells and secretions from several accessory glands in the male reproductive system.
Approximately five percent of semen consists of sperm cells, while the remaining ninety-five percent consists of fluids produced by the seminal vesicles, prostate gland, and bulbourethral glands.
The seminal vesicles contribute the largest portion of semen volume. Their secretions contain fructose, which serves as an energy source for sperm cells.
The prostate gland produces a slightly alkaline fluid that helps protect sperm from the acidic environment of the female reproductive tract.
The bulbourethral glands secrete a lubricating fluid that neutralizes residual acidity in the urethra prior to ejaculation.
Together, these fluids create an environment that supports sperm survival, mobility, and fertilization potential.
Changes in semen composition may indicate underlying reproductive problems. For example, low semen volume or abnormal pH levels may suggest dysfunction of accessory glands.
Laboratory analysis of semen provides valuable information erotic for diagnosing fertility issues.
