Question: 1 / 400

What does anestrus refer to?

Ovarian inactivity

Anestrus refers to a phase in the reproductive cycle where there is a lack of ovarian activity. During this period, the ovaries do not produce mature eggs, and thus no estrus (heat) occurs, making it a time of reproductive dormancy. This phase is important for animals as it allows for periods of rest between cycles of fertility, enabling recovery and preparation for future reproductive activities.

The other options pertain to different aspects of the reproductive cycle. Active ovulation signifies a period where eggs are being released, which is not applicable to anestrus. Follicle development indicates the maturation of ovarian follicles leading to ovulation, which is also absent during anestrus. Lastly, the phase of mating behavior suggests active reproductive activities, which does not occur during the inactivity that characterizes anestrus.
