The aim of this study is to compare the three commonly used hysterosalpingography (HSG) injection devices on the basis of patient pain perception, total fluoroscopic and procedural time, and side effects in a prospective, randomized study. An important and novel secondary outcome is the comparison of the quality of images obtained with these three devices. The investigators hypothesize that the balloon catheter and cervical vacuum cup will be less painful than the acorn tipped cannula and that there will be no difference in image quality between the three groups.
