The urgency of the problem. Clinical studies indicate that the tuboperitoneal factor is the most common cause of infertility (40 - 70%). It is known that the informative value of the indirect methods for assessing the state of the pelvic organs (ultrasound scanning, GHA, EchoGss), widely used to date, does not exceed 60 - 70%. The direct visualization method - transabdominal laparoscopy (LS) - is highly informative, almost 100%. However, at the diagnostic stage, the use of this method is not always justified, because requires hospital conditions, general anesthesia, is quite aggressive and invasive. In this regard, the endoscopic method - fertiloscopy (a combination of transvaginal hydrolaparoscopy, chromohydrotubation and hysteroscopy), which is distinguished by simplicity and ease of implementation, seems to be promising.The aim of the study was to study the availability and information content of fertiloscopy in the examination of patients with infertility.
