What happens in the uterus when progesterone levels suddenly decrease?
Proliferation
Ovulation
Menstruation
Implantation
The Correct Answer is C
A. Proliferation: Refers to the rebuilding of the endometrium under estrogen influence during the follicular phase, not linked to progesterone withdrawal.
B. Ovulation: Triggered primarily by a surge of luteinizing hormone (LH), not by decreased progesterone.
C. Menstruation: Sudden drop in progesterone (and estrogen) causes shedding of the endometrial lining, leading to menstruation.
D. Implantation: Occurs when a fertilized embryo attaches to a progesterone-maintained endometrium, so decreased progesterone would prevent this.
