Dominant follicle

Question

Dominant follicle

ScanSolve AI Tutor · Accepted Answer

A dominant follicle is the one follicle that is selected from a cohort of developing follicles each menstrual cycle to mature fully and ovulate. Step 1: During the follicular phase, several follicles begin to grow, stimulated by FSH. Step 2: As they grow, they produce estrogen. The follicle that produces the most estrogen and is most sensitive to FSH becomes the dominant follicle. Step 3: This dominant follicle continues to grow rapidly, suppressing the growth of other follicles through mechanisms like producing inhibin, which reduces FSH secretion. Step 4: The dominant follicle eventually matures and is ready to release an egg during ovulation.
