Tubal infertility, in particular proximal tubal occlusion (PTO) (15–25%), is gaining increasing attention. In the case of bilateral tubal occlusion, in vitro fertilization (IVF) is indicated since the expected pregnancy rate (EPR) is the same as can result from macrosurgical methods. The pregnancy rate after microsurgical procedures can go up to 60–70%. Despite the fact that better and encouraging results are being obtained by sophisticated assisted reproduction techniques, IVF procedures that are performed unnecessarily or not indicated objectively can result in serious consequences. Therefore, there is no question that refining the procedures used for evaluating the fallopian tubes is extremely important in order to reduce the physical and psychological burden on the patients, as well as from the viewpoint of cost effectiveness. We recommend a diagnostic method to ensure tubal patency in one session. The procedure is easy to perform and, according to our experience, the examination is highly accurate.
