Patient: I have done IVF in Shanghai Ji’ai for 3 times without success, the doctor did not say what the reason is, I don’t know what to do now? Should I continue or give up, I don’t know if I can still succeed? I had a hysteroscopy at the doctor’s request a year ago, and my tubes are still open but not smooth, and one side is open but not smooth. I would like to know why the embryo is good but never made it, what is the reason and what other tests should I do? Thank you! Li Wen, Department of Obstetrics and Gynecology, Shanghai Changzheng Hospital: Hello, the success rate of IVF is about 40~50% at present, and there is no guarantee that it will be successful.
