What Human Reproduction covers

Topics in the NEET (UG) 2026–27 syllabus for this chapter.

  • Male and female reproductive systems
  • Microscopic anatomy of testis and ovary; gametogenesis- spermatogenesis and oogenesis
  • Menstrual cycle
  • Fertilisation, embryo development up to blastocyst formation, implantation
  • Pregnancy and placenta formation, parturition, lactation (elementary idea)

Past NEET questions on Human Reproduction

Try each one, then open the answer and explanation.

Question 1 · NEET 2025

Consider the following: A. The reductive division for the human female gametogenesis starts earlier than that of the male gametogenesis. B. The gap between the first meiotic division and the second meiotic division is much shorter for males compared to females. C. The first polar body is associated with the formation of the primary oocyte. D. Luteinizing Hormone (LH) surge leads to disintegration of the endometrium and onset of menstrual bleeding. Choose the correct answer from the options given below:

  1. A.A and B are true
  2. B.A and C are true
  3. C.B and D are true
  4. D.B and C are true
Show answer

Answer: A. A and B are true

For human gametogenesis, spermatogenesis starts at puberty while oogenesis starts during fetal life, so A (female starts earlier) is correct. First polar body forms after meiosis I in oogenesis, linked to secondary oocyte, not primary oocyte, so C is incorrect. LH surge causes ovulation, not endometrial disintegration; that's due to progesterone fall, so D is false. B: in males, meiosis I and II occur continuously; in females, meiosis II occurs after fertilization, so gap much shorter in males — B is true. Thus only A and B true.

Question 2 · NEET 2025

The first menstruation is called:

  1. A.Menopause
  2. B.Menarche
  3. C.Diapause
  4. D.Ovulation
Show answer

Answer: B. Menarche

Menarche is defined as the first occurrence of menstruation in a female's life, marking the onset of puberty. Menopause is the end of menstruation, diapause is delayed development, and ovulation is release of an egg.

Question 3 · NEET 2025

Match List-I with List-II. List-I List-II A. Head I. Enzymes B. Middle piece II. Sperm motility C. Acrosome III. Energy D. Tail IV. Genetic material Choose the correct answer from the options given below:

  1. A.A-IV, B-III, C-I, D-II
  2. B.A-IV, B-III, C-II, D-I
  3. C.A-III, B-IV, C-II, D-I
  4. D.A-III, B-II, C-I, D-IV
Show answer

Answer: A. A-IV, B-III, C-I, D-II

Head contains nucleus (genetic material). Middle piece has mitochondria (energy). Acrosome contains enzymes for fertilization. Tail provides motility. A-IV, B-III, C-I, D-II.

Question 4 · NEET 2025

Find the correct statements: A. In human pregnancy, the major organ systems are formed at the end of 12 weeks. B. In human pregnancy the major organ systems are formed at the end of 8 weeks. C. In human pregnancy heart is formed after one month of gestation. D. In human pregnancy, limbs and digits develop by the end of second month. E. In human pregnancy the appearance of hair usually observed in the fifth month. Choose the correct answer from the options given below:

  1. A.A and E Only
  2. B.B and C Only
  3. C.B, C, D and E Only
  4. D.A, C, D and E Only
Show answer

Answer: C. B, C, D and E Only

Key milestones in human embryology: major organ systems formed by end of 8 weeks (end of embryonic period), not 12 weeks. Heart forms earlier (by ~4 weeks). Limbs/digits develop by end of second month (8 weeks). Appearance of hair (lanugo) occurs around fifth month. Correct statements: B, C, D, E.

Question 5 · NEET 2024

Match List-I with List-II relating to human female external genitalia. List I (Structures) List II (Features) A. Mons pubis I. A fleshy fold of tissue surrounding the vaginal opening B. Clitoris II. Fatty cushion of cells covered by skin and hair C. Hymen III. Tiny finger-like structure above labia minora D. Labina majora IV. A thin membrane- like structure covering vaginal opening Choose the correct answer from the option given below:

  1. A.A-II, B-III, C-IV, D-I
  2. B.A-IV, B-III, C-II, D-I
  3. C.A-I, B-IV, C-III, D-II
  4. D.A-II, B-III, C-I, D-IV
Show answer

Answer: A. A-II, B-III, C-IV, D-I

Mons pubis is fatty cushion with hair (II). Clitoris is small projection above labia minora (III). Hymen is membrane covering vaginal opening (IV). Labia majora are fleshy folds surrounding vaginal opening (I). Hence A-II, B-III, C-IV, D-I.
