As spermatozoa leave the testes and are joined by fluids from the prostate and seminal vesicles,they become motile because seminal fluid contains an external energy source.What is that energy source?

Question

Quizplus · Accepted Answer

Seminal fluid contains high levels of fructose, which serves as an energy source for spermatozoa. This allows them to swim and move towards the egg for fertilization. The other options mentioned (glucose, glycogen, Ca⁺⁺, and K⁺) are not present in high enough concentrations in seminal fluid to serve as a significant energy source for spermatozoa.
