Observe the figure and answer the following questions:

What is the function of corpus luteum?

Secretion of progesterone

The correct answer is Option (1) → Secretion of progesterone

The corpus luteum is a temporary endocrine structure that forms in the ovary from the remnants of the ovarian follicle after ovulation. Its primary function is to produce progesterone, a hormone crucial for preparing and maintaining the uterine lining for potential implantation of a fertilized egg (embryo). If fertilization occurs, the corpus luteum continues to produce progesterone to support early pregnancy until the placenta takes over this function. If fertilization does not occur, the corpus luteum regresses, leading to a decrease in progesterone production and triggering the start of a new menstrual cycle.
