When assisted reproductive technologies are used, recurrent implantation failures are observed in 7.7–67.5% of patients with chronic endometritis (CE). 
Objective: To develop a predictive model of the probability of clinical pregnancy and live birth in women with uterine infertility due to CE using neural network technology at the stage of selection for in vitro fertilization (IVF) programs with cryotransfer and evaluate the effectiveness of this model.
Materials and methods: The secondary analysis of the results of the TULIP-2 randomized controlled trial was carried out. A total of 188 patients who met the objectives of this analysis were selected from the electronic database. The patients were divided into two comparison groups: group I (n=102) included patients who became pregnant, group II (n=86) included those who did not become pregnant.
Results: The model of predicting the success of IVF was created on the basis of 11 most significant parameters, which were identified after obtaining the results of the logistic analysis. The model was made using neural network technology. In order to predict the outcome of IVF, the following indicators were included in the structure of the multilayer perceptron: treatment, which included a complex of antimicrobial peptides and cytokines, CD-138, pulsation index in radial arteries according to Dopplerometry, oxygenation indices, proliferative activity, structuring according to laser conversion testing, interleukins such as -4, -10, -1ß, tumor necrosis factor-α according to enzyme immunoassay. The accuracy of the prediction was 97.9% (sensitivity is 100.0%, specificity is 96.4%). The information value of the model was confirmed by ROC analysis, the area under the curve (ROC-AUC) was 0.9, p<0.001. An online calculator was developed for the practical use of the model of individual prediction of IVF success.
Conclusion: The model of predicting clinical pregnancy and live birth as a result of IVF in patients with infertility caused by chronic endometritis, using neural network technology, has a high predictive accuracy and makes it possible to determine the need for administering another course (courses) of treatment for chronic endometritis or making a decision on the IVF procedure.
