Sample item

What hormonal event triggers ovulation?

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

The answer and the reasoning

D. Luteinizing hormone surge

A midcycle luteinizing hormone surge triggers ovulation and luteinization of the ruptured follicle, following sustained high estrogen feedback.

Option by option

  • A. Thyroxine surge

    Thyroxine does not trigger ovulation.

  • B. Prolactin surge

    Prolactin primarily supports milk synthesis.

  • C. Oxytocin surge

    Oxytocin mediates uterine contraction and milk ejection.

  • D. Luteinizing hormone surge (correct)

    Correct: LH surge triggers ovulation.

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.
