Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Increased secretion of progesterone
Concept:

The defining characteristic of the second half of the menstrual cycle is uterine preparation for pregnancy.

Solution:

  • The luteal phase corresponds directly to the secretory phase in the uterus.


  • During this time, the corpus luteum dominates ovarian function.


  • Its primary physiological action is the increased secretion of progesterone, which halts endometrial growth and stimulates the uterine glands to secrete glycogen-rich fluids.


Why other options are incorrect:

FSH and LH are suppressed by negative feedback during the luteal phase. While estrogen is secreted, its major peak occurs during the preceding follicular/proliferative phase, making progesterone the defining "increased" hormone of the luteal phase.
