Sample item

What maintains the corpus luteum during early pregnancy?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Human chorionic gonadotropin

Human chorionic gonadotropin from the early trophoblast maintains corpus luteum progesterone production until placental hormone production is established.

Option by option

  • A. Prolactin

    Prolactin supports milk production.

  • B. Human chorionic gonadotropin (correct)

    Correct: hCG preserves the progesterone-secreting corpus luteum.

  • C. Inhibin B

    Inhibin B suppresses FSH in other reproductive contexts.

  • D. Oxytocin

    Oxytocin promotes uterine contraction and milk ejection.

How should I study Reproductive physiology?

For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud. Then use the flashcards and the other Physiology questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
