The criteria for the diagnosis of polycystic ovary syndrome are as follows: 1. Sporadic ovulation or non-ovulation. Patients with polycystic ovary syndrome have sporadic ovulation or non-ovulation, which may affect fertility in most cases. However, this is not absolute. Some patients with sporadic ovulation, although their menstruation is irregular, may ovulate in a certain month and young couples have more frequent intercourse, so this sporadic ovulation can be easily caught and does not affect their conception. 2. Such patients have no egg discharge, which can affect their conception. If these patients have fertility needs, they should go to the reproductive medicine department, where a doctor specializing in reproductive endocrine diseases will provide symptomatic treatment. Some patients need lifestyle modification and supportive medications such as ovulation medication to allow the eggs to be expelled and conception to take place.
