Which one of the following structures is not a male sex accessory duct?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Mons pubis
The male sex accessory ducts are the rete testis, vasa efferentia, epididymis and vas deferens. They store and carry sperms from the testis to the outside.
(1) Rete testis — A male sex accessory duct. It receives the sperms from the seminiferous tubules.
(2) Mons pubis — Not a male sex accessory duct. It is a cushion of fatty tissue covered by skin and pubic hair. It is part of the female external genitalia.
(3) Epididymis — A male sex accessory duct. It lies along the back of each testis and stores sperms.
(4) Vas deferens — A male sex accessory duct. It carries sperms up from the epididymis towards the urethra.
NCERT Extract:
The Male Reproductive System – “… 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.”
The Female Reproductive System – “… The female external genitalia include mons pubis, labia majora, labia minora, hymen and clitoris …. Mons pubis is a cushion of fatty tissue covered by skin and pubic hair.”
