Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Progesterone
Concept:

The post-ovulatory phase (luteal phase) is dedicated to preparing the uterus for pregnancy.

Solution:

  • Once the mature follicle expels the ovum, it collapses and is modified by LH into a glandular structure called the corpus luteum.


  • The primary role of this corpus luteum is to mass-produce progesterone.


  • Progesterone maintains and vascularizes the endometrial lining, ensuring it is thick and secretory in case a fertilized embryo arrives to implant.


Why other options are incorrect:

FSH and LH are pituitary hormones. While the corpus luteum secretes some estrogen, progesterone is its primary and defining product. Testosterone is predominantly a male hormone.
