Sample questions on Human Reproduction with answers
8 questions from the practice bank, spread across the chapter's topics. The full set is in the app.
Question 1: Female Reproductive System and Menstrual Cycle
The first milk produced by a mother after delivery, rich in antibodies, is called:
- A prolactin
- B colostrum
- C casein
- D lactose
Answer: B. colostrum
Why: It contains IgA antibodies that give the newborn passive immunity.
Question 2: Fertilisation, Implantation and Pregnancy
The corpus luteum secretes mainly:
- A progesterone
- B FSH
- C oxytocin
- D testosterone
Answer: A. progesterone
Why: Progesterone maintains the endometrium needed for implantation and pregnancy.
Question 3: Male Reproductive System and Spermatogenesis
The sequence of ducts through which sperms pass from the testis is:
- A rete testis → vasa efferentia → epididymis → vas deferens → ejaculatory duct → urethra
- B vas deferens → epididymis → rete testis
- C epididymis → rete testis → urethra → vas deferens
- D urethra → vas deferens → epididymis
Answer: A. rete testis → vasa efferentia → epididymis → vas deferens → ejaculatory duct → urethra
Why: The ejaculatory duct receives the secretion of the seminal vesicle.
Question 4: Female Reproductive System and Menstrual Cycle
A sharp surge of luteinising hormone (LH) around the 14th day of the menstrual cycle triggers:
- A menstruation
- B ovulation
- C implantation
- D formation of the corpus luteum only after a delay
Answer: B. ovulation
Why: The LH surge at mid-cycle induces rupture of the Graafian follicle, releasing the ovum in the process called ovulation.
Question 5: Fertilisation, Implantation and Pregnancy
The amniotic fluid surrounding the foetus:
- A supplies it with blood
- B protects it from mechanical shock
- C produces hormones
- D fixes it to the uterus
Answer: B. protects it from mechanical shock
Why: The amnion is the membrane enclosing it.
Question 6: Male Reproductive System and Spermatogenesis
The seminal vesicles secrete a fluid that is rich in:
- A fructose, calcium and some enzymes, providing the energy source for the sperm
- B amino acids only
- C fats
- D pepsin
Answer: A. fructose, calcium and some enzymes, providing the energy source for the sperm
Why: The fluid forms the major part of semen.
Question 7: Female Reproductive System and Menstrual Cycle
In the ovary, an egg is produced in the:
- A oviduct
- B uterus
- C Graafian follicle, which ruptures at ovulation
- D corpus luteum
Answer: C. Graafian follicle, which ruptures at ovulation
Why: The follicle then becomes the corpus luteum.
Question 8: Fertilisation, Implantation and Pregnancy
The hormone that stimulates strong uterine contractions during the delivery of the baby is:
- A progesterone
- B oxytocin
- C prolactin
- D FSH
Answer: B. oxytocin
Why: The signals for parturition originate from the fully developed foetus and the placenta.
