Hints & Solutions
(a) If the vasa efferentia in the human reproductive system get blocked the gametes will not be transformed from testes to epididymis. The seminal vesicles produce a viscous, fructose-rich fluid forming around $65-70$ percentage of the semen base. The white color of the semen is due to secretion from the prostate glands containing enzymes, citric acid, lipids, and acid phosphatase. This forms around $25-30$ percentage of the semen base. At each ejaculation around 200-500 million sperms are released by the testes. This forms about $2-5$ percentage of the semen composition.
