Tubal Patency Check
Test for Tubal Patency
Our First Step Fertility Check is aimed at people who are wondering if they might have a problem.
Patients of Merrion Fertility Clinic may be referred on to have a number of additional investigations involving surgery or radiology. These investigations are carried out either in the National Maternity Hospital, Holles Street or in St Vincent’s Private Hospital.
What is hysterosalpingogram?
A hysterosalpingogram (HSG) is a test to find out if there is any abnormality in the uterus or fallopian tubes.
An examination similar to a smear test is performed. A speculum is inserted into the vagina and a very fine catheter is inserted into or through the cervix. Radiographic contrast (dye) is injected into the uterine cavity through the vagina and cervix. If the fallopian tubes are open, the dye will then fill the tubes and spill out into the abdominal cavity. X-rays are taken to show the dye going into the uterus and tubes and outlining the fallopian tubes.
Why is hysterosalpingogram done?
The HSG test is a way to determine whether the fallopian tubes are open or blocked. If the tubes are blocked, the dye will not pass through. If the tubes are swollen and dilated (i.e. a hydrosalpinx) this will show up as distended on the X-ray.
HSG can also determine the location of a blockage, whether at the junction of the fallopian tube and the uterus (proximal) or at the end of the fallopian tube (distal).
A fertility infection screen (Chlamydia test) is required for all patients as standard prior to the HSG procedure.
