Which one of the following is NOT a component of human male reproductive system?
- (a)Cervix
- (b)Urethra
- (c)Seminal vesicle
- (d)Vas deferens
Correct — A, cervix. The cervix is the narrow lower neck of the uterus and belongs to the FEMALE reproductive system, so it is not a male organ. The other three are all parts of the male tract: the urethra carries semen (and urine) out through the penis, the seminal vesicle is an accessory gland that adds fluid to semen, and the vas deferens is the duct that conveys sperm from the epididymis toward the urethra.
- (b)Urethra — In males the urethra is part of the reproductive tract too — it is the common passage that carries both urine and semen out of the body, so it is a male component.
- (c)Seminal vesicle — The seminal vesicles are male accessory glands that secrete a fructose-rich fluid making up much of the semen, so they are part of the male system.
- (d)Vas deferens — The vas deferens (ductus deferens) is the muscular tube that transports sperm from the epididymis to the ejaculatory duct — a core male reproductive structure.
The human male reproductive system comprises the testes (which make sperm and testosterone), the epididymis and vas deferens (which store and transport sperm), the accessory glands (seminal vesicles, prostate and bulbourethral glands, which form seminal fluid), and the urethra and penis (which deliver semen). The cervix, uterus, fallopian tubes, ovaries and vagina belong to the female system.
The trap is that 'cervix' sounds like a neutral anatomical term, so it can slip past. The key is to recognise it as the neck of the uterus — a strictly female structure — while all the other options are unmistakably male ducts or glands.
- Cervix = lower neck of the uterus, part of the female reproductive system.
- Vas deferens carries sperm from the epididymis toward the urethra.
- Seminal vesicles and prostate are male accessory glands forming seminal fluid.
- In males the urethra is a shared passage for urine and semen.
Cervix is a female structure; the vas deferens, seminal vesicle and (male) urethra are male.
- Cervix sounds like a generic anatomical term but is specifically female (neck of the uterus).
- Forgetting that the urethra in males doubles as part of the reproductive tract, not just the urinary system.
Asked as a 'NOT a component' odd-one-out — separate male ducts/glands from a female structure slipped into the list.
In human beings, normally in which one of the following parts does the sperm fertilize the ovum?
- (a) Cervix
- (b) Fallopian Tube
- (c) Lower Part of Uterus
- (d) Upper Part of Uterus
Answer(b) Fallopian Tube
Same domain — human reproductive anatomy, and both feature the cervix. UPSC 2007 tests where fertilisation occurs in the female tract (the fallopian tube, with cervix as a distractor); this NDA item tests that the cervix is female, not part of the male system.

Which one of the following is NOT a component of the human female reproductive system?
- (a)Fallopian tube
- (b)Ovary
- (c)Prostate gland
- (d)Cervix
Answer(c) Prostate gland — it is a male accessory gland; the others are all female organs.

The seminal vesicles in the human male reproductive system mainly
- (a)produce sperm
- (b)secrete fluid that forms part of the semen
- (c)store urine
- (d)produce testosterone
Answer(b) secrete fluid that forms part of the semen — a fructose-rich secretion nourishing the sperm.
