The Foam study, an award-winning paper at the American Society of Reproductive Medicine (ASRM) Scientific Congress in 2019 concluded that ExEm® Foam has been proven to have similar effectiveness to X-Ray HSG. In addition to supporting the effectiveness of HyFoSy with ExEm® Foam, this European randomized clinical trial of 1,167 patients in 26 hospitals found that 12-month pregnancy outcomes were similar in subfertile women who received HyFoSy with ExEm® Foam versus X-ray HSG. The FOAM study was published in February 2022 in the Human Reproduction journal (an Oxford University Press journal).
