Question

Briefly describe the role of fructose in seminal fluid.

Answer 1

Answer – Semen is male reproductive fluid that contains spermatozoa in suspension. Semen work as a vehicle for the transport of sperm.

First portion of the ejaculation is composed of sperm and prostatic exudates namely citric acid, proteases, acid phosphates. Later portion secreted by seminal vesicles has fructose, prostaglandins, coagulating elements and bicarbonates for defending the acidic environment of vagina. That is why it also acts as marker of seminal vesicle functionality. The seminal plasma has excessive concentrations of fructose that provides an anaerobic and aerobic source of energy for the sperm. Fructose also provides progressive sperm motility and viscosity in the semen. Fructose is the source of energy for spermatozoa and act as resource for metabolism and motility of sperm.
