The aim of this study was evaluation of uterine factors in sterility and infertility using hysterosalpingographic and hysteroscopic techniques. Sixty five women ranged in age from 22 to 40 years were included in this study. The results of performed hysterosalpingographies and hysteroscopies were compared. Intrauterine changes found during diagnostic procedures were removed in operative hysteroscopy and the effectiveness of this treatment was estimated by pregnancy rate. The most frequent changes found within cervical canal and uterine cavity were adhesions and endometrial polyps. The rate of uterine septa and submucous myomas were considerable lower. Hysteroscopy was found the best diagnostic method in evaluation of intrauterine conditions for fertility and considerably increased the range of information about the type and location of uterine abnormalities. The removal of those changes during operative hysteroscopy increased the fertility rate in women treated with this procedure.
