What is a Hycosy Test?

A Hycosy test uses ultrasound imaging to test if your fallopian tubes are open.
The fallopian tubes play a vital role in natural conception.

They are the place where sperm and egg meet and where the embryo is nurtured for the first five days of its existence. At iTrust fertility we test them using the HyCoSy scan.

Who is it for?

  • Women who would like to test the patency of the fallopian tubes
  • Those who wish to undergo inter-uterine insemination (IUI) are also advised to undergo a HyCosy
  • Patients with endometriosis, pelvic infection or appendicitis
  • Patients with endometriosis

What does it involve?

This procedure involves placing a thin catheter into the uterus. A small balloon on the tip is then inflated to seal the uterus entrance. Once in place, a small amount of effervescent fluid is injected into the uterus.

With the use of 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 from the end of each tube, tubal patency is confirmed. If this fails to happen, the tubes may be damaged.

The procedure is like an internal examination such as a smear test and is available at both our centres. It is best carried out between day eight and day 15 of your cycle, although it can be done at any time after bleeding has stopped.

Is a HyCoSy test painful?

The levels of pain for the HyCosy test varies from woman to woman but it is likely that you will feel some discomfort during the procedure similar to that of period pain.
