The tubal patency test (hysterosalpingography) is an essential part of a couple’s infertility evaluation. At I.R.I.S MED we innovate and apply a new painless technique, without exposure to radiation that comes to change the data and replace the classic hysterosalpingography. The new Ultrasound Polysaccharide (ExEmFoam) (HyFoSy) ultrasonography method assesses the patency of the fallopian tubes and may also examine the outline of the uterine cavity with the ability to detect possible uterine abnormalities. It is performed by injecting a foam shader into the uterine cavity which is then directed towards the fallopian tubes while at the same time it is imaged by ultrasound. The duration of the test is about 15 minutes and takes place between the 6th and 10th day of the cycle.Tubal patency test-HyFoSy
