Laparoscopy has already brought a revolution in surgery, and its magic and greatness can be seen by eradicating the disease through 2-3 small holes of 5-10 mm in the abdominal wall. Most of the examinations and surgeries for infertility patients are reconstructive rather than destructive, which requires minimizing the damage and achieving the best results, and laparoscopy is obviously the best choice for infertility patients. The main pelvic factors of infertility are endometriosis, tubal infection, pelvic adhesions, pelvic tuberculosis, and uterine fibroids. The laparoscope can magnify the object 2 to 3 times, and with the formation of pneumoperitoneum, the abdominal and pelvic cavities are clearly visible, so that the abdominal and pelvic cavities can be observed comprehensively, the morphological structure and lesions of the pelvic organs can be evaluated accurately, and the corresponding surgery can be performed according to the lesions, such as pelvic adhesion decomposition, tubal ostomy, electrocautery of endometriosis lesions, ovarian cyst stripping, uterine fibroid removal, polycystic ovary perforation etc., for the treatment of infertility. Endometriosis is one of the important causes of infertility. In the past, the diagnosis and treatment of this disease were difficult, but the application of laparoscopy has enabled the diagnosis of patients who showed only infertility without clinical symptoms and signs in the early stage, and laparoscopy can detect the typical foci of ectopic disease, such as purple-blue nodules, red flame-like polyps, ovarian chocolate cysts, pelvic adhesions, etc. Therefore, laparoscopy is the gold standard for the diagnosis of endometriosis. The procedure, together with postoperative medication, can significantly improve the conception rate. The pelvic tuberculosis patients only show infertility without other symptoms, but the consequences are serious, about 90%~100% of the lesions are in the fallopian tubes, which cause irreversible damage to the fallopian tubes, and the conception rate is very low, so early diagnosis is very important. The cause of the disease can be determined by biopsy. Laparoscopic myomectomy and pelvic adhesion release can not only achieve the purpose of open surgery, but also have less trauma, less postoperative adhesions, and faster postoperative recovery, resulting in a higher chance of conception after surgery. Laparoscopy cannot solve all the problems of infertility, but it is the first choice of infertility patients for examination and those who need surgical treatment, and its use with hysteroscopy has been the first choice of infertility patients for diagnosis and treatment. It is believed that with the development of technology, laparoscopy will play an increasingly important role in the diagnosis and treatment of infertility.
