The female menstrual cycle is hormonally regulated by the hypothalamic-pituitary-ovarian axis. In short, we can summarize the entire process as follows:
- The pituitary gland releases gonadotropins FSH and LH, which activates the development and maturation of eggs in the ovary.
- Simultaneously, ovarian growth leads to the release of estrogen and progesterone, which will allow endometrial growth to favor embryo implantation.
- The brain will be notified about the increase in estrogen and progesterone levels. As a result, it will reduced FSH and LH levels.
- At the same time, progesterone and estrogen levels will decrease, closing the feedback regulation cycle of the menstrual cycle.
