Which one of the following structures is not essential for maturation and motility of sperms?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Cervix
Sperms leave the seminiferous tubules and travel through the male accessory ducts.
(1) Epididymis — Essential for the maturation and motility of sperms. NCERT names its secretions.
(2) Cervix — Not essential for the maturation and motility of sperms. It is the narrow lower part of the uterus in the female reproductive tract. It is not part of the male system.
(3) Seminal vesicle — Essential for the maturation and motility of sperms. NCERT names its secretions.
(4) Prostate — Essential for the maturation and motility of sperms. NCERT names its secretions.
NCERT Extract:
Gametogenesis – “… Sperms released from the seminiferous tubules, are transported by the accessory ducts. Secretions of epididymis, vas deferens, seminal vesicle and prostate are essential for maturation and motility of sperms. The seminal plasma along with the sperms constitute the semen.”
The Female Reproductive System – “… The uterus opens into vagina through a narrow cervix. The cavity of the cervix is called cervical canal (Figure 2.3b) which alongwith vagina forms the birth canal.”
