Sex hormone release by the ovary is dependent on the phase of the menstrual cycle.
During the first phase of the cycle, the follicular phase, the follicles are developing. Finally, the dominant follicle will turn into a preovulatory follicle, starting to release estrogens as it continues its maturation process.
After ovulation, during the luteal phase of the menstrual cycle, preovulatory follicles turn into the corpus luteum, which releases progesterone.
On the other hand, antral and preantral follicles that form the ovarian reserve produce a hormone called Anti-Müllerian hormone throughout the entire cycle, regardless of the phase.
