Human tubal fluid collection via vagina and its quantitative variations during the menstrual cycle

The culdoscope was used for easy approach to the fallopian tube, which was delivered into the vagina, and a Foley catheter (No. 8 French) was introduced through its fimbrial end for collection of human tubal secretion. It was left from one to eight days. The technique was successful in 54 cases out of 60, but we succeeded in collecting enough fluid in 44 cases only. The volume of human tubal fluid was studied in relation to the phase of the cycle. A peak of fluid volume was found to occur at the midcycle.
