What phase of the ovarian cycle begins with the release of the oocyte?
Ovulation is the phase in which a mature ovarian follicle ruptures and discharges an ovum (also known as an oocyte, female gamete, or egg) Ovulation also occurs in the estrous cycle of other female mammals, which differs in many fundamental ways from the menstrual cycle
What are the phases of ovulation?
Ovulation divides the two phases of the ovarian cycle (the follicular phase and the luteal phase) What: An egg is released from the ovary into the fallopian tube The dominant follicle in the ovary produces more and more estrogen as it grows larger
