Bilateral ovaries with polycystic-like changes are usually morphologic changes on ultrasound. One ovary or both ovaries with a number of follicles greater than or equal to 12 per ovarian section, or a volume greater than 10 ml per ovary, is only an alteration under ultrasound. Many women have polycystic ovarian changes, but not necessarily polycystic ovary syndrome. 25%-30% of women may have normal ovulation in combination with abnormal menstruation, such as delayed or absent menstruation, which does not require special treatment. In addition, most women may have a combination of high androgens, small follicles, sporadic ovulation, or high body mass index, which are some of the changes of polycystic ovary syndrome, and in this case, the diagnosis should be confirmed with endocrine blood sampling or temperature monitoring of menstrual cycle.
