Current evidence suggests that Hysterosalpingo-Foam Sonography test (HyFoSy) has emerged as a new option to make Fallopian tubes assessment easier. Several published studies have compared the different types of tubal patency tests available with the accepted gold standard, laparoscopy and dye, endorsing the advantages of HyFoSy over the other techniques. However, we wonder why professionals nowadays do not indicate HyFoSy as a first-choice diagnostic tool and X-ray hysterosalpingography (HSG) is still the most recommended in outpatients. The aim of this review is to highlight the latest updates on this topic trying to raise awareness about the benefits put forward by HyFoSy as well as providing some tips to take advantage of the moment in which HyFoSy is performed to obtain the máximum information in a single consultation.
