If a woman examines the ultrasound and finds that there are small follicles on the ovaries, it means that there are small blisters appearing on the ovaries, and the nature of the small follicles may be physiological follicles or cysts, which need to be comprehensively judged according to the other circumstances. If it happens to be around 5 days after a woman’s menstrual period is clean, small follicles are found on the ovary, and the small follicles are found to grow significantly on the next day’s review of the ultrasound, it is considered to be a physiological follicle, and the follicle usually grows up to about 2cm and is discharged from the ovary, and there are no obvious small follicles appearing on the next day’s review after the menstrual period is clean. However, if women check ultrasound found small follicles on the ovary, and small follicles continue to appear, it should be considered to be caused by physiological cysts, but also may be caused by other pathologic cysts, often small follicles can be temporarily without special treatment treatment.
