During the estrous cycle, ovulation typically occurs during which phase?

Explanation:
Ovulation is timed with the period when the female is sexually receptive, which is estrus. In this phase, rising estrogen levels trigger an LH surge that releases the mature egg from the ovary. Proestrus involves follicle growth and increasing estrogen but not ovulation yet. Metestrus occurs after ovulation as the ruptured follicle becomes the corpus luteum, and diestrus is the luteal phase dominated by progesterone. So the phase when ovulation typically occurs is estrus.
