Min was so happy when she got pregnant that she referred her classmate Ying to see her. Ying had been married for more than three years without contraception and had not conceived. She worked in Beijing and visited at least ten major hospitals in Beijing. At least three or four hospitals in Beijing suggested her to do IVF, but Ying could not make up her mind because she was always worried that the percentage of birth defects would be higher in IVF babies. As a result, she tried all kinds of options, such as Chinese medicine, western medicine and injections, but could not conceive. Later, she came all the way to me for consultation and her medical history was as thick as a book. After analyzing her case, I suggested laparoscopic surgery. Because of Minnie’s successful experience and the many detours she had taken before, Ying was very receptive. Intraoperatively, she was confirmed to have pelvic endometriosis, ovarian coeliac cyst, partial adhesions, and bloody ascites, but her fallopian tubes were patent. Due to the difference in her disease condition and the fact that she did not work locally, she was given follow-up treatment for three months after surgery, with one injection per month (brought back to Beijing for the injection). After three months, she came back for monitoring on her vacation and conceived successfully in the second month. Therefore, the same endometriosis, the intraoperative situation is different, and the postoperative treatment plan depends on the situation. The main cause of Ying’s endometriosis is ovarian coeliac cyst, which affects ovulation. Many people do not understand this point, because it is obvious that there is ovulation in the preoperative examination, so why is it said to affect ovulation? In fact, there are many pseudo-ovulation, or empty eggs, that are ineffective, so they remain infertile, and even many fertility specialists cannot tell the difference. Many doctors can do laparoscopic surgery, but doing it down and doing it well are two different things. It is also very important to be very clear after surgery where the key point of infertility is, the same endometriosis, some are pelvic environment problems, some are ovulation problems, and ovulation problems are also divided into anovulation, pseudo-ovulation, small follicle ovulation, etc., there are at least a dozen different forms, only to distinguish the different, in order to develop a suitable plan, in order to be more effective.
