How long does it take to mature a follicle 15 x 14?

Follicles of this size will be discharged after about 2 days. Because the normal follicle growth rate is 1.5-2mm per day, when the follicle diameter reaches 20mm, it will rupture and exclude eggs. Therefore, when monitoring ovulation by B ultrasound, it must be seen that the follicle ruptures and discharges eggs, and the clinical diagnosis is normal ovulation. Because some people due to thick follicular wall, or due to insufficient hormone levels in the body, even if the follicle has reached a dominant state, still can not be discharged, this situation is clinically called follicular luteinization, so further examination and treatment are needed to ovulation.
