Sample item

What triggers ovulation in a normal menstrual cycle?

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

The answer and the reasoning

B. Mid-cycle luteinizing hormone surge

A mid-cycle surge of luteinizing hormone triggers final oocyte maturation and rupture of the dominant follicle, releasing the ovum.

Option by option

  • A. Fall in follicle-stimulating hormone after menopause

    Menopause does not represent the ovulatory cycle mechanism.

  • B. Mid-cycle luteinizing hormone surge (correct)

    Correct: LH surge is the immediate ovulatory trigger.

  • C. Rise in prolactin during breastfeeding

    Prolactin can suppress ovulation rather than trigger it.

  • D. Sustained progesterone peak before follicular growth

    Progesterone rises mainly after ovulation from corpus luteum.

How hard is this question?

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

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.
