medium MCQ 2 marks Class 12 · Biology · Human Reproduction
  1. A) Follicle‑stimulating hormone (FSH)
  2. B) Luteinizing hormone (LH)
  3. C) Progesterone
  4. D) Estrogen
Answer
C) Progesterone

The correct answer is C) Progesterone — Conclude that progesterone is the hormone chiefly responsible for maintaining the endometrial lining during the luteal phase.

Step-by-step solution

  1. Recognize that the luteal phase follows ovulation and is marked by the formation of the corpus luteum.
  2. Recall that the corpus luteum secretes large amounts of progesterone into the bloodstream.
  3. Understand that progesterone converts the proliferative endometrium into a secretory, receptive state suitable for implantation.
  4. Conclude that progesterone is the hormone chiefly responsible for maintaining the endometrial lining during the luteal phase.
Common mistake: Choosing estrogen instead of progesterone
