Polycystic Ovary Syndrome (PCOS) is a metabolic disease and a lifelong condition that cannot be cured. The main symptom is irregular menstruation, which can manifest as infrequent menstrual periods or absence of menstruation. If menstruation does not occur for more than two months, it is essential to take oral progestogens, such as progesterone or dydrogesterone, for 12 days. After stopping the medication, menstruation should resume. This is mainly to protect the endometrium, as not menstruating for an extended period prevents it from shedding. Under the influence of unopposed estrogen, there might be excessive proliferation, leading to precancerous changes in the endometrial lining and potentially developing into endometrial cancer over time. Therefore, it is crucial to have a menstrual period at least every two months to protect the endometrium. (Medication should be taken under the guidance of a physician.)
