What is the stage of estrus in which ova develop in the ovary?

• A. Metestrus
• B. Estrus
• C. Proestrus
• D. Diestrus

Answer: (C)

Proestrus is the stage when ovarian follicles grow and the ova mature. During this phase, developing follicles produce increasing amounts of estrogen, preparing both the ovaries and the reproductive tract for potential mating. Ovulation, the release of the mature oocyte, typically happens later, as the animal moves into estrus. After ovulation, the cycle progresses through metestrus and diestrus, involving the formation and activity of the corpus luteum. So, the development and maturation of ova in the ovary occur during proestrus.
