The best time to treat polycystic ovary syndrome is to provide active treatment once it is detected. Moreover, polycystic ovary syndrome needs to be supervised until menopause, because polycystic ovary syndrome may lead to scanty menstruation or amenorrhea. Once amenorrhea occurs, the endometrium will continue to proliferate under the effect of estrogen, which will likely lead to endometrial lesions and even develop into endometrial cancer, so intervention should be given to regularly allow the endometrium to shed for menstruation so that it will not cause excessive stimulation of the endometrium. In addition, if you are planning to get pregnant, it is recommended to lower the androgen if the androgen is high and then give ovulation treatment; if you are not planning to get pregnant, you can do artificial cycle treatment after the androgen is lowered to normal.
