Seminal Vesicle Secretion Quiz

Glands and Their Functions

• Prostate Gland: Secretes a milky, slightly acidic fluid containing citric acid, acid phosphatase, and proteolytic enzymes.
• Bulbourethral Glands (Cowper's Glands): Produces mucus for lubrication and an alkaline substance that neutralizes acids in the urethra and female reproductive tract.
• Seminal Vesicles: Secrete an alkaline, viscous fluid that helps neutralize acidic environments in the male urethra and female reproductive tract.

Key Components of Seminal Fluid

• Fructose: Serves as the main energy source for sperm cells, enhancing their motility and viability.
• Coagulation Protein: The primary protein responsible for semen coagulation post-ejaculation is called fibrinogen.
• Semen Composition: Primarily composed of sperm cells, seminal fluid, and various secretions from seminal vesicles, prostate, and bulbourethral glands.

Semen Behavior After Ejaculation

• Initial State: Semen is initially viscous and coagulated after ejaculation.
• Re-liquefaction Process: Enzymes such as prostate-specific antigen (PSA) break down the coagulated semen, allowing it to re-liquefy for sperm motility.

Sperm Motility and Viability

• Contributors: Fructose and other components in the seminal fluid crucially support sperm motility and overall viability.
