Painless, radiation-free, accurate: These are the advantages of hysterosalpingography, which can detect whether your fallopian tubes – or at least one of them – are blocked and therefore whether there will be difficulties in the union of egg and sperm. With this brand-new method called HyFoSy, you can correctly assess whether there is a possibility of infertility, as approximately 30% of infertility cases are due to blocked fallopian tubes.
Methods of assessing tubes
If you want to become pregnant, it is very important to check the permeability of your fallopian tubes, among other things. It is necessary to know that normal fallopian tubes cannot be visualized with a conventional ultrasound scan. So, it takes a bit more to get a complete picture. The traditional methods of assessing the tubes are Hysterosalpingography (HSG) and Hysteroscopy. Recently, a new foam contrast agent has been developed, which has greatly improved the quality of the examination: this test is called Hysterosalpingo-Foam-Sonography (HyFoSy).
Prerequisites for HyFoSy
The examination takes on average 30-45 minutes and can only be performed under the following conditions:
1. If there is no blood loss (period)
2. If you are not pregnant (i.e., if you are in the first part of your cycle or have not had unprotected intercourse since the start of your last period, or if you are using contraception)
3. If there is no inflammation in the lower abdomen.
You should also be aware that the examination cannot be carried out if the ultrasound reveals a dilation of one of the fallopian tubes (called “hydrosalpinx” in medical jargon).
How does the test work?
Before: About an hour before your appointment, we advise you to take a painkiller to prevent or avoid abdominal pain. Please also empty your bladder before the test.
During the test: A vaginal ultrasound is performed. Then, after insertion of a speculum into the vagina (as for test PAP), samples are taken. The cervix is then disinfected, followed by the insertion of a small catheter into the uterine cavity. The speculum is then removed, and a small amount of a mixture of water and air (foam) is injected through the catheter, all under transvaginal ultrasound control. This fluid will fill the uterine cavity, and if the tubes are patent, the fluid will reach the abdominal cavity via the fallopian tubes. You may feel cramps in your lower abdomen, as sometimes happens during your period. Do not hesitate to tell the doctor about any pain you feel during the examination.
You can now get an overall assessment of your fallopian tubes. Please contact Medimall IVF Clinic to book your appointment and find out more.
