Quizplus · Accepted Answer

The ovarian cycle begins with the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland, stimulated by the hypothalamus. This initiates the growth and maturation of the ovarian follicles, leading to ovulation and the formation of the corpus luteum. FSH and LH levels are low at the beginning of the ovarian cycle and increase in response to hypothalamic signals. Estrogen and progesterone levels also fluctuate during the ovarian cycle but are not the initial trigger for its start.
