Why does the luteal phase exhibit relatively stable progesterone levels, rather than precipitous drops as follicles degrade?

💡 Explanation

The corpus luteum develops from the follicle post-ovulation and sustains progesterone production during the luteal phase, because it is a temporary endocrine gland responsible for maintaining the uterine lining. Therefore, progesterone levels remain relatively stable, rather than dropping rapidly as follicles degrade; this function ensures the uterus is prepared for potential implantation.
