Weightage: what the paper actually did

Human Reproduction carried 8 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Sample PYQs from this chapter

Real questions NTA asked from Human Reproduction, with the answer and the working. Try before you peek.

Question 1 · NEET 2026

Which of the following hormone is not secreted by human placenta?
  1. A.hCG
  2. B.Estrogen
  3. C.Progesterone
  4. D.LH
Answer and explanation

Answer: D

The placenta functions as a temporary endocrine gland, producing hCG, human placental lactogen, oestrogens, progestogens and later relaxin. Luteinising hormone is not among them - LH is a gonadotropin secreted by the ANTERIOR PITUITARY. The placental hormone that mimics its role early in pregnancy is hCG, which sustains the corpus luteum. NCERT Class 12, Human Reproduction.

Question 2 · NEET 2026

Given below are two statements: Statement I: Ovulation is caused by LH surge leading to rupture of Graafian follicles. Statement II: Graafian follicle remaining after ovulation transform into corpus luteum and secretes large amount of estrogen. In the light of the above statements, choose the most appropriate answer from the options given below:
  1. A.Both Statement I and Statement II are correct
  2. B.Both Statement I and Statement II are incorrect
  3. C.Statement I is correct but Statement II is incorrect
  4. D.Statement I is incorrect but Statement II is correct
Answer and explanation

Answer: C

A mid-cycle surge of luteinising hormone ruptures the mature Graafian follicle and releases the ovum. The remaining follicle forms the corpus luteum, whose main secretion is progesterone; it helps maintain the endometrium for implantation. Statement I is true, while statement II wrongly names oestrogen as the principal secretion.
