Can Hysterosalpingo-Foam Sonography Replace Hysterosalpingography as First-Choice Tubal Patency Test? A Randomized Non-inferiority Trial
This randomized trial compared hysterosalpingo-foam sonography (HyFoSy) against hysterosalpingography (HSG) to determine if HyFoSy is a non-inferior first-choice test for tubal patency.

This randomized non-inferiority trial evaluated whether hysterosalpingo-foam sonography could replace hysterosalpingography (HSG) as a first-choice test of tubal patency in the fertility workup. Using a patient-friendlier sonography-based approach, the study compared diagnostic performance against HSG and reported that hysterosalpingo-foam sonography met non-inferiority criteria. A key caveat noted in the abstract is the clinical context that tubal pathology—including that associated with endometriosis—is a contributor to infertility, but the trial’s comparison is focused on test accuracy rather than infertility outcomes. Relevance to endometriosis: the paper cites endometriosis as one cause of tubal pathology contributing to female infertility, though the study’s main focus is comparing two tubal patency testing methods.
