Ultrasound is used to detect polycystic ovaries, so ultrasound can detect polycystic ovaries. If the ultrasound indicates polycystic ovaries, it does not indicate that the woman has polycystic ovary syndrome, but should be combined with whether the woman has hyperandrogenism and whether she has menstrual disorders and abnormal uterine bleeding. In this case, we should consider whether the woman has polycystic ovary syndrome in combination with whether she has hyperandrogenism and whether she has menstrual disorders, abnormal uterine bleeding, sporadic ovulation or non-ovulation. Therefore, the mere detection of polycystic ovaries by ultrasound does not confirm that a woman needs to be highly concerned at this time, or that polycystic ovary syndrome is the cause of the problem, and that follow-up examinations are needed.
