The follicular phase is defined by the growth and maturation of follicles within the ovaries, as evidenced by [1], [2], and [3]. During this phase, follicle-stimulating hormone drives the development of these follicles, leading to the selection of a dominant follicle as described in [4], [5], and [6].

claimAs estrogen levels rise during the follicular phase, the hormone acts as a switch to turn off the production of follicle-stimulating hormone (FSH), limiting the number of follicles that prepare eggs for release.
claimDuring the follicular phase, one dominant follicle matures in an ovary while suppressing the growth of other follicles, causing the non-dominant follicles to stop growing and die.
procedureDuring the follicular phase of the menstrual cycle, the brain releases follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which travel through the blood to the ovaries to stimulate the growth of 15 to 20 eggs, each contained within a follicle.

claimHigh estrogen levels toward the end of the follicular phase trigger the pituitary gland to release a surge of luteinizing hormone (LH), which causes the mature egg to be released from the follicle and ovary during ovulation.
claimDuring the follicular phase, fluid-filled sacs in the ovaries called follicles house immature eggs.

claimDuring the follicular phase, changing hormone levels cause the uterine lining to thicken and follicles to grow on the surface of the ovaries, with usually one follicle maturing into an egg.
claimThe follicular phase begins on the first day of a period and lasts for 13 to 14 days, during which changing hormone levels cause the uterine lining to thicken and follicles to grow on the ovaries.

claimDuring the follicular phase, multiple fluid-filled sacs containing eggs, known as follicles, develop in both ovaries, with one becoming the dominant follicle that is most likely to release a mature egg.
claimDuring the follicular phase of the ovarian cycle (which corresponds to the proliferative phase of the uterine cycle), the follicle in the ovary prepares an egg and the uterine lining rebuilds.

quote“This cohort of follicles has been slowly maturing over the last three to four months, and then eight to 20 of them become fully mature during the follicular phase of the menstrual cycle, says Dr. O’Connor. “Of the follicles that mature, one of them becomes what’s called the dominant follicle.”

claimDuring the follicular phase, follicle-stimulating hormone (FSH) causes follicles in the ovaries to grow, and between days 10 and 14, one follicle forms a mature egg (ovum).

claimDuring the follicular phase, serum estradiol levels rise in parallel with the growth of follicle size and the increasing number of granulosa cells.
