Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Testosterone
Concept:

Secondary sexual characteristics are the physical traits that distinguish biological males and females, manifesting at puberty.

Solution:

  • Testosterone, an androgen produced by the testes, drives the entire physical masculinization of the body.


  • It not only ensures the continued production of sperm but also deepens the voice, increases muscle mass, and promotes facial and body hair growth.


Why other options are incorrect:

Estrogen and progesterone dictate female reproductive cycles and characteristics.
