Test of fallopian tube patency

Assessing fallopian tube patency is one of the first steps in treating infertility.

If the fallopian tubes are obstructed, there is little chance of natural conception. Even intrauterine insemination (IUI) is not the answer in this case. Conception is only possible with IVF, where the embryo is transferred directly into the uterus. For this reason, assessing fallopian tube patency is one of the basic tests for women who can’t conceive. There are a number of methods to test fallopian tube patency, but the simplest and most conclusive is ultrasound with a contrast agent (contrast-enhanced ultrasound).

How is an ultrasound performed?

We use the ExEm® Foam Kit for patency testing. Foam is created by mixing ExEm® gel and purified water, and this is used to fill the fallopian tubes. Ultrasonography images are then taken to determine tubal patency. Foam has much better visibility on ultrasound than, for example, a saline solution.

What's going on in your body?

The patency and functionality of the fallopian tubes is vital in the reproductive process. The egg and sperm meet in the fallopian tube, which subsequently ensures that the fertilised egg travels to the uterine cavity, where the embryo implants (nests) and continues to grow.

In case of obstructed or dysfunctional fallopian tubes, the embryo may attach in the wrong place, resulting in an ectopic pregnancy. Completely blocked fallopian tubes are then the cause of infertility. The most common causes of blocked fallopian tubes are inflammation (e.g. ovarian inflammation, uterine inflammation, chlamydial inflammation), endometriosis or adhesions following inflammation or previous surgery in the abdominal cavity.
