Hysterosalpingo Contrast Sonography: HyCoSy

Hysterosalpingo Contrast Sonography: HyCoSy

Here at Leeds Fertility we have a number of different ways to find out which treatment will most suit the needs of each of our patients.

HyCoSy is one of the investigations available, which will enable us to assess your fallopian tubes and uterine cavity. It is within the fallopian tube the sperm fertilizes the egg and the resulting embryo is transferred into the womb where it implants. It is important that your fallopian tubes are open and HyCoSy will provide that information.

HyCoSy will be recommended to assess the possibility of any blockages to your fallopian tubes.  We will only do this if you do not have any of the following risk factors:

  • symptoms suggestive of endometriosis
  • a previous pelvic infection, such as chlamydia and gonorrhoea
  • previous ectopic pregnancy
  • any previous surgery involving uterus, ovaries or fallopian tubes and some forms of abdominal surgery

Some women may be advised to have a hysterosalpingography - a form of x-ray examination. You may be also be advised to have a laparoscopy and dye test (key-hole surgery) if you have any of the above risk factors.

This procedure involves passage of a small tube into the uterine cavity through the cervix through the womb cavity and the fallopian tubes that can be seen on a transvaginal (internal) ultrasound scan. It usually takes 20-30 minutes and most women tolerate the procedure well.
