Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Progesterone
Concept:

During the luteal phase and pregnancy, it is necessary to prevent the release of additional eggs.

Solution:

  • Progesterone is secreted by the corpus luteum (and later the placenta).


  • High circulating levels of progesterone exert a strong negative feedback on the hypothalamus and anterior pituitary.


  • This suppression prevents the release of FSH and the LH surge. Without an LH surge, subsequent follicle maturation and ovulation are entirely suppressed.


Why other options are incorrect:

FSH promotes follicle development. Insulin regulates blood glucose. Prolactin promotes milk production (though very high prolactin can indirectly suppress ovulation, progesterone is the primary physiological cycle regulator).

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.
