Are my fallopian tubes working?
Using ultrasound, we can tell if your tubes are open.
The fallopian tubes play a vital role in natural conception. They are the place where sperm and egg meet and which nurture the growth of the embryo for the first 5 days of its existence. We test the fallopian tubes by the HyCoSy test.
This test involves placing a thin catheter into the uterus. A small balloon on the tip is inflated to seal the uterus entrance. Once the catheter is in place a small amount of effervescent fluid is then injected into the uterus.
By ultrasound imaging the fluid can be tracked in real time as it passes from the uterus and through the fallopian tubes. If the fluid is seen spilling out of the end of each tube, tubal patency is confirmed. If fluid is not seen passing the tubes and spilling out from the end, the tubes may be damaged.
The procedure is similar to an internal examination like a smear test and is best carried out between day 8 and day 15 of your cycle, although it can be done at any time after bleeding has stopped.
