Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Estrogen and Progesterone
Concept:

Successful embryo implantation requires the combined, sequential actions of the primary ovarian steroid hormones.

Solution:

  • Estrogen is responsible for the initial proliferation and rebuilding of the endometrial lining (thickening).


  • Progesterone follows up by vascularizing the lining, making it secretory, spongy, and highly receptive.


  • Together, this pair of hormones synergistically maintains a stable, nutrient-rich uterine environment essential for embryo implantation.


Why other options are incorrect:

FSH and LH are pituitary hormones that act on the ovaries to cause the release of estrogen and progesterone, rather than acting directly on the uterine endometrium themselves.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
