Q. If for some reason, the vasa efferentia in the human reproductive system get blocked, the gametes will not be transported from :

(a) Testes to epididymis

(b) Epididymis to vas deferens

(c) Ovary to uterus

(d) Vagina to uterus

Solution :

Correct option : A In humans, the male sex accessory ducts include rete testis, vasa efferentia, epididymis and vas deferens. The seminiferous tubules of the testis open into the vasa efferentia through rete testis. The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis. If the vasa efferentia in the human reproductive system get blocked, the sperms will not be able to pass from testes to epididymis. So, the correct answer is ‘Testes to epididymis’
