Patients with polycystic ovary syndrome who are taking eusebio, which means they are not currently planning to get pregnant, take eusebio for the purpose of making the endometrium shed periodically and will not suffer from delayed menstruation or amenorrhea due to polycystic ovary syndrome, because when menstruation does not come, the endometrium may become diseased under the stimulation of estrogen. The purpose of taking Ustekin is to make the endometrium shed periodically, so that the endometrium will not undergo the corresponding lesions. For polycystic ovary syndrome, it should be supervised until menopause is approaching. If no corresponding treatment is given, it may cause amenorrhea and the endometrium may become diseased.
