Two hundred patients have been reviewed in whom culdoscopy or laparoscopy was performed for infertility study. During these two procedures, methylene blue was injected through an endocervical cannula for detection of tubal patency under direct visualization. When compared with 89 patients tested by utero-tubal insufflation and hystero-salpingography, results indicated that direct visualization of the tubes and dye hydrotubation appears to be the most reliable method. HSG proved to be the second most reliable method with a failure rate of 19.2%. The least accurate procedure in this study was UTI with CO2 gas, where the failure rate was 24.7%. The latter lest, however, is the most efficient one for detecting tubal spasm.
