Polycystic ovary syndrome (PCOS) and polycystic ovaries are different. Firstly, polycystic ovaries are diagnosed through ultrasound, wherein more than 12 small follicles are found in both ovaries simultaneously under ultrasound guidance. This condition can occur in some normal women as well as women who have been taking short-acting birth control pills for a long time. In subsequent check-ups, this condition might not be detected. On the other hand, polycystic ovary syndrome is a disease represented by a cluster of clinical symptoms. For instance, women may experience infrequent ovulation, longer menstrual cycles, and it can also lead to infertility. There are also manifestations of increased androgen levels, such as increased body hair and facial acne. Polycystic ovary syndrome primarily affects a woman's normal fertility functions and thus requires treatment; whereas, polycystic ovaries usually just require observation.
