What defines the composition of the fluid secreted by seminal vesicles?

• A. Rich in proteins
• B. Contains fructose
• C. Rich in hormones
• D. Alkaline in nature

Answer: (B)

The composition of the fluid secreted by the seminal vesicles is primarily characterized by the presence of fructose. This sugar serves as a primary energy source for sperm motility after ejaculation, enhancing their ability to travel within the female reproductive tract. Seminal vesicle fluid contributes to the overall volume of semen and contains various nutrients, with fructose being a crucial element for supporting the metabolic needs of sperm cells. While proteins and hormones are involved in other aspects of reproductive physiology, fructose is specifically noteworthy in the context of seminal vesicle fluid. The alkaline nature of the fluid helps to neutralize the acidity of the female reproductive tract, but this characteristic is a secondary factor to the essential role that fructose plays in sperm energy supply.
