The follicular phase is the first phase of the menstrual cycle, and it is characterized by the rapid development of ovarian follicles. During this phase, follicle-stimulating hormone (FSH) is released from the pituitary gland, which stimulates the growth of several follicles in the ovaries. These follicles begin to produce estrogen, which causes the uterine lining to thicken in preparation for potential pregnancy. The follicular phase ends with ovulation, when one dominant follicle releases a mature egg.
