There are two types of anovulation, one is the absence of a dominant follicle and the other is the development of a dominant follicle but not ovulation. For those who do not have dominant follicles, especially those with polycystic ovaries, first of all, before preparing for pregnancy, it is important to make adequate preparations under the guidance of a professional doctor, including regulating irregular menstrual cycles and keeping body weight within a reasonable range; secondly, when preparing for pregnancy, you can use intercourse during ovulation to increase the chance of conception. The most common method is to take ovulation test by yourself or go to the hospital for ultrasound follicle monitoring by a professional doctor. If the follicles are not well developed, medication can be used to predict the time of ovulation and guide intercourse to control the best time to conceive. For those who have a dominant follicle but have not ovulated, medication (e.g. chlortetracycline) can be administered when the dominant follicle is mature, which can often yield very good results. In addition, in some cases where the ovaries are normal but not ovulating due to surrounding inflammation, assisted reproductive technology is also available to help you achieve your dream of a good pregnancy.
