Tubal pathology is a causative factor in 20% of subfertile couples. Testing of tubal patency (hysterosalpingography) is one of the necessary tests in the context of investigating a female infertility. Assisting Nature IVF unit, innovates and implements a new technique, painless, non-ionizing radiation that changes data and replaces classic hysterosalpingography with comparable results but which patient-friendly.

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 carried out by injecting the foamed shadow into the cavity of the uterus, which is then directed towards the fallopian tubes while being ultrasounded. The duration of the test is 15-30 minutes and can take place on any day of the cycle (preferably between the 6th and 10th day of the cycle).
The benefits of the new HyFoSy method, implemented by the Assisting Nature scientists, make it patient-friendly and varied:

  • There is no exposure to radiation
  • It is a less painful process
  • Less time-consuming than HSG
  • The examination itself, due to infusion of the foam, improves the patency of the fallopian tubes
  • Absence of allergy risk using a special hypoallergenic foam
  • No side effects have been observed having been applied to more than 60,000 patients.
  • Performed in an external clinic

Why do I need this test?

The examination gives the physician the necessary information about the tubal patency (that is, that your fallopian tubes are open and allow your eggs to travel freely within them, where they are fertilized by the sperm and the embryo is directed to the uterus where implanted)
It is necessary for women with conception difficulties, women who have undergone surgical procedures in the peritoneal cavity, and women with peritoneal cavity infections (which may have caused adhesions and have occluded the fallopian tubes).

When will I know the results?

Your doctor may inform you during the procedure, but you should book an appointment with one of our infertility expertised physicians to evaluate the results of HyFoSy hysterosalpingography and your medical history as well as your partner in order to evaluate the reasons infertility.
Our unit with the most experience in the implementation of HyFosSy Ultrasonography HyperSurgery and its absolute specialization in the field of infertility organized the 1st workshop for the training of doctors and obstetricians in Greece in the framework of an international conference.
