Sample item

Which hormonal event directly 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. Midcycle luteinizing hormone surge

Sustained high estradiol late in the follicular phase switches to positive feedback and triggers the LH surge, which causes ovulation and luteinization. Progesterone rises after ovulation.

Option by option

  • A. Progesterone fall at menstruation

    Progesterone withdrawal triggers menstruation at cycle end.

  • B. Midcycle luteinizing hormone surge (correct)

    Correct. LH surge is the immediate ovulatory trigger.

  • C. Continuous high FSH only

    FSH supports follicular development but is not the direct ovulatory trigger.

  • D. Prolactin surge

    Prolactin is not the normal ovulation trigger.
