Here's a more detailed explanation:

* Ova: The ovary contains follicles, which are structures that hold and nurture developing eggs. When an egg matures, it is released from the ovary during ovulation.

* Hormones: The ovary also produces hormones, such as estrogen and progesterone, which play essential roles in the menstrual cycle, pregnancy, and female sexual development.

* Corpus luteum: After ovulation, the follicle transforms into a corpus luteum, which continues to produce hormones until the end of a menstrual cycle if pregnancy doesn't occur.

So, while the ovary itself is not "formed" into anything, it is responsible for producing the egg, which is essential for reproduction.
