In the follicular phase, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are released from the anterior pituitary, which matures the ovarian follicle called the graafian follicle. There are no changes in the secretions of the cervical mucus. The development of the corpus luteum occurs in the luteal phase of the ovarian cycle. During the follicular phase, the progesterone and estrogen levels are low, not high.
