Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Ovulation stage
Concept:

The physiological trigger for the release of the egg requires a massive, temporary spike in hormone levels.

Solution:

  • Right at the end of the follicular/proliferative phase, estrogen levels peak, causing a positive feedback loop.


  • This triggers the anterior pituitary to release a massive "surge" of LH.


  • This LH surge directly causes the follicle to rupture. Therefore, LH levels are at their absolute maximum exactly during the ovulation stage (around day 14 of a 28-day cycle).


Why other options are incorrect:

During the menstrual, proliferative, and secretory stages, LH levels are relatively low and stable, held in check by negative feedback from estrogen and progesterone.
