Normal ovulation is instantaneous, a process in which the follicular fluid is discharged after the follicle ruptures and disappears quickly. If the follicles become smaller after a certain degree of enlargement during ovulation, it is possible that the follicles have shrunk without normal ovulation. You can observe whether the menstrual period is regular or not, and examine the follicles with ultrasound for three consecutive months to observe whether they have normal ovulation. If follicular dysplasia occurs over a long period of time, you should consider using ovulation stimulating drugs, and pay attention to your diet and eat less cold and raw food, as well as less stimulating food, and it is recommended that you increase your nutritional intake and try to have a regular work schedule.
