Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Testosterone production
Concept:

Male characteristics and reproductive functions are driven by androgens synthesized in the testes.

Solution:

  • Leydig cells (interstitial cells) are located in the spaces between the seminiferous tubules in the testes.


  • When stimulated by Luteinizing Hormone (LH) from the pituitary, they synthesize and secrete androgens, primarily testosterone.


  • Testosterone is vital for both spermatogenesis and the maintenance of secondary male sexual characteristics.


Why other options are incorrect:

FSH is produced by the anterior pituitary. Sperm production occurs within the seminiferous tubules by germ cells. Leydig cells produce testosterone, they do not inhibit it.

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.
