Director Ma Ning is a famous reproductive expert, a "closed disciple" of Professor Xia Enlan, the mother of hysteroscopy in China, and an authoritative expert on hysteroscopy in the treatment of infertility. Director Ma has nearly 30 years of clinical experience in hysteroscopy and has received nearly 10,000 operations. He is also a hysteroscopy expert with the largest amount of surgery in Fuxing Hospital. When I went to her clinic, I found that many patients had abnormal uterine cavity problems, such as hysteromyoma, intrauterine adhesions, endometrial polyps, uterine diaphragm and so on. Moreover, Director Ma's operation is very meticulous, and he will solve all the problems at once as much as possible, so as not to let patients do hysteroscopy repeatedly, and also pay great attention to protecting the fertility of pregnant women. If you are in Beijing, I suggest you see Director Ma.
