The follicular phase is the phase that begins with the first day of menses (Cycle Day 1) . During the early part of this phase, the pituitary gland increases the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH stimulates the growth of numerous follicles in the ovary as well as the release of estrogen from the ovary. The estrogen causes the thickening of the endometrium. Generally, only one of the follicles matures and gets to release the ovum (egg) contained within. LH is secreted in a sudden burst mid-cycle (around Cycle Day 13-14) and stimulates the release of the ovum from the mature follicle in the ovary.

The follicle ruptures and releases the ovum (egg) into the funnel-shaped end of the fallopian tube. The ovum then makes its way down the tube and into the uterus, hoping to get fertilized along the way.
