Infertility has a serious impact on women’s physical and mental health, as it is the main function and social responsibility of women to bear a child. Tubal disease and uterine abnormalities are the main causes of infertility. If a couple has a normal sexual life after marriage and has not been pregnant for one year without contraception, or if they have been pregnant for six months without contraception, they should be examined and treated for infertility. Premature intervention, irregular diagnosis and treatment can often lead to more serious consequences. The traditional methods of examining the fallopian tubes and uterus are: tubal lavage, tubal angiography, pelvic ultrasound (3D negative ultrasound is best), etc. With the wide popularity of hysteroscopy and laparoscopy in clinical practice, they have played a great role in the diagnosis and treatment of infertility. Studies have shown that the diagnostic value of hysteroscopy and laparoscopy is significantly higher than that of traditional hysterosalpingography, negative ultrasound, tubal lavage, etc., and lesions found during the examination can be treated simultaneously. Both hysteroscopy and laparoscopy have the advantages of being non-operative, safe, less bleeding, faster postoperative recovery and higher postoperative pregnancy rate, therefore, they have become common means of female infertility examination and treatment. Hysteroscopy can directly and clearly observe the situation in the uterine cavity of infertility patients, understand whether there are intrauterine factors causing infertility, and make necessary surgical treatment for abnormal conditions, such as endometrial polyp removal, removal of submucosal fibroids, separation of uterine cavity adhesions, and removal of longitudinal diaphragm of the uterus, etc. More importantly, hysteroscopic tubal intubation can be performed to check the patency of the fallopian tubes, and if the fallopian tubes are not open or blocked, a guide wire can be applied at the same time to check the patency of the fallopian tubes. If the fallopian tubes are not open or obstructed, a guidewire can be used to unblock the tubes at the same time, with very satisfactory results. Laparoscopy can diagnose the causes of infertility in the pelvic cavity and clearly observe the lesions in the uterus, ovaries and fallopian tubes; and perform treatment at the same time, such as separating pelvic adhesions (adhesions in the uterus, ovaries, fallopian tubes and pelvic wall), performing various kinds of tubal plastic surgery and removing endometriosis lesions. The combined application of hysterolaparoscopy in infertility patients has advantages over laparoscopy or hysteroscopy alone. Hysteroscopic tubal orifice cannulation is effective for the treatment of proximal tubal obstruction and partial adhesions in the tubal lumen, while laparoscopic surgery is mainly for the treatment of pelvic adhesions and distal tubal obstruction, and the combination of the two can achieve the best treatment effect. During the treatment, the surgeon should always implement a minimally invasive concept to reduce damage to the uterus and fallopian tubes, reduce complications, and enhance comprehensive management before, during and after surgery. After the combined diagnosis and treatment of hysteroscopy, both doctors and patients are able to understand the real cause of infertility very intuitively, avoiding later transitional examinations and treatments, reducing the waste of money, and also providing a strong basis and condition for the next step of guiding conception and assisted reproduction (such as IVF). The Third Affiliated Hospital of Zhengzhou University, or Henan Provincial Maternal and Child Health Hospital, is one of the first hospitals in China to carry out gynecological endoscopy technology, with first-class electronic hysteroscopy and laparoscopy equipment and a team of experts with excellent surgical skills, who provide the best quality service to every infertility patient with minimally invasive concepts, the smallest instruments, the most advanced technology and the most economical price. Minimally invasive techniques coupled with minimally invasive concepts are required to achieve the best results.
