What is a key function of the corpus luteum after ovulation?

• A. Producing estrogen and progesterone
• B. Stimulating ovulation
• C. Releasing the ova
• D. Maintaining the endometrial lining

Answer: (A)

The corpus luteum plays a crucial role in the menstrual cycle following ovulation by producing both estrogen and progesterone. After the follicle releases an egg during ovulation, it transforms into the corpus luteum, which is essential for preparing the body for a potential pregnancy. The hormones released by the corpus luteum, particularly progesterone, are vital for thickening the endometrial lining, creating a suitable environment for embryo implantation.

Estrogen produced by the corpus luteum also contributes to the maintenance of the endometrium and plays a role in further regulating the menstrual cycle. Thus, the production of these hormones by the corpus luteum is vital in supporting reproductive functions and facilitating early pregnancy if fertilization occurs. The emphasis on hormone production highlights the significance of the corpus luteum's role in the female reproductive system post-ovulation.
