Question

If the epididymis is not present then what will happen?
A. Life cycle of sperm will be short.
B. Sperms cross the whole pathway at an early stage.
C. Functional maturation is early.
D. Sperm will be incapable for fertilization.

Answer 1

Hint: Male reproductive system comprises a pair of testes with the accessory ducts, glands and external genitalia. The epididymis is one of the accessory ducts; it connects the vasa efferentia and vas deferens.

Complete answer:
Male reproductive system comprises a pair of testes with accessory ducts, glands and external genitalia. Testes are situated outside the abdomen that is in the scrotum, it is so because to maintain the low temperature for survival of sperm. The male accessory ducts consist of rete testis, vasa efferentia, epididymis and vas deferens. These ducts help in the transportation and maturation of sperm. The ducts also receive the ducts of male accessory glands that are the seminiferous vesicle, prostate and of the bulbourethral gland. These gland secretions are rich in fructose, calcium and many enzymes, as well as they, provide lubrication to the penis. The penis is the male external genitalia. The epididymis is a long coiled tube in which the immature sperms get matured and it takes about 14 days to mature the sperm in epididymis.
Option A: If the epididymis is not present the life cycle of sperm wouldn’t be short as it is formed in a seminiferous tubule. So, the wrong option.
Option B: No, the sperms cannot cross the pathway at an early stage. So, the wrong option.
Option C: The functional maturation cannot take place early in case of the absence of epididymis. So, again the wrong option.
Option D: If the epididymis is not present then the sperms will be incapable for fertilization as the sperms cannot be matured.

Hence, option D is the correct option.

Note:
The correct sequence of the transportation of sperms in male reproductive is firstly from the seminiferous tubules here the sperm get formed, then rete testis after that Vasa efferentia this follows the Epididymis, then comes Vas deferens further Ejaculatory duct comes in the role after that Urethra and finally the Urethral meatus.
