What is the name of the ovarian scar that forms after luteolysis?

The ovarian scar that forms after luteolysis is known as the corpus albicans. This structure is a white body that develops from the degeneration of the corpus luteum, which occurs when pregnancy does not take place. The corpus luteum is a temporary endocrine structure involved in producing hormones, mainly progesterone, which is crucial for maintaining the uterine lining in the early stages of pregnancy.

When fertilization and implantation do not occur, luteolysis ensues, leading to the breakdown of this structure. As the corpus luteum degrades, it leaves behind connective tissue that eventually forms the corpus albicans. This represents the final stage in the lifecycle of the follicle that was involved in ovulation.

In contrast, a follicle refers to any of the sac-like structures in the ovaries that contain immature eggs, while the Graafian follicle is a mature follicle that is ready for ovulation. The corpus luteum is, of course, the active structure that forms right after ovulation and not a scar. The distinction between these terms is important for understanding the ovarian cycle and the role of hormones in female reproductive biology.
