Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: ICSH
Concept:

Hormones often have alternative names based on their specific physiological target in males versus females.

Solution:

  • In females, LH triggers ovulation and luteinization.


  • In males, the exact same molecule targets the interstitial cells (Leydig cells) in the testes to stimulate testosterone production. Hence, it is biologically referred to as Interstitial Cell Stimulating Hormone (ICSH).


Why other options are incorrect:

ACTH targets the adrenal cortex. TRF (Thyrotropin-Releasing Factor) is from the hypothalamus. MSH affects melanocytes.

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.
