Solution

The correct option is A Vas deferens and epididymis are the only accessory ducts found in the male reproductive system

The male accessory ducts include rete testes, vasa efferentia, epididymis and vas deferens. The ducts are involved in the storage of sperms and also help in transporting them outside the urethra during ejaculation.
Semen is the fluid that comprises secretion of various accessory glands such as Cowper’s gland, seminal vesicle and prostate gland, accessory ducts such as the epididymis and the secretion of seminiferous tubules of the testis. Seminal plasma is the fluid, non-cellular portion of semen. It is rich in calcium, fructose, and certain enzymes that provide nourishment and protection to the sperms.

Spermatogonia (sperm mother cells) are the male germ cells found in the wall of the seminiferous tubules. They undergo meiosis to produce haploid male gametes, spermatozoa (sperm cells) by a process known as spermatogenesis.

Secretion of all the accessory ducts such as rete testis, vasa efferentia, epididymis and vas deferens and accessory glands contributes to semen volume which helps in the proper functioning of sperm.
