What is HyCoSy, Procedure & its Side Effects

HyCoSy test is a short, non-invasive medical procedure used to evaluate the health of the uterus and fallopian tubes. It involves inserting a small, flexible catheter through the vagina and cervix into the uterus.

This article covers various aspects of a HyCoSy procedure, including what is HyCoSy, its detailed procedure and its risks. Read on to learn more!

What is HyCoSy?

Hysterosalpingo-contrast-sonography or HyCoSy test is a diagnostic ultrasound procedure used to assess the health of the uterine lining. It is also sometimes called a uterine cavity scan.

During the procedure, a transvaginal ultrasound probe is used to create images of the inside of the uterus.

HyCoSy can be used to check for any abnormalities in the uterine lining, such as uterine  polyps or fibroids. Doctors also use it to assess the thickness of the uterine lining, which is an important factor in fertility.

HyCoSy is a safe and quick procedure that can be performed in your doctor’s office.

What to expect during the HyCoSy exam?

If you are experiencing pelvic pain or other abnormal symptoms, your doctor may recommend a HyCoSy test. This diagnostic procedure is used to assess your fallopian tubes and uterus health.

During a HyCoSy procedure, a small catheter is inserted into the vagina. Then, a saline solution is injected through the catheter and into the uterine cavity. This solution helps to improve the clarity of the fluorescent x-ray images that are then used to assess the health of your fallopian tubes and the uterus.

The HyCoSy procedure generally takes less than 30 minutes to complete. During the procedure, you might experience mild cramping.

During the procedure

HyCoSy test is usually performed by a radiologist, obstetrician, or gynaecologist. The procedure takes place in an outpatient setting.

The doctor inserts a speculum into the vagina to visualize the cervix.

A thin, flexible tube (catheter) is inserted through the cervix into the uterus. A contrast agent is then injected through the catheter.

Once the saline solution has been injected, x-rays are taken of the pelvis. The images will show the outline of the uterus and fallopian tubes. If there is any blockage or obstruction in the uterus or fallopian tubes, it will be apparent on the x-ray.

Are there any side effects of the HyCoSy procedure?

Although the HyCoSy procedure is generally safe, some risks and side effects are associated with it, such as the following:

  • Cramping and discomfort: This is the most common side effect and is usually mild and goes away within a few hours.
  • Nausea and vomiting: Some may feel nauseous after the procedure, and a few may vomit. 
  • Bleeding: There may be some spotting or light bleeding after the procedure, which is generally nothing to worry about.
  • Infection: While there is a risk of infection after the procedure, doctors typically treat it at once with antibiotics.
  • Allergic reaction: In rare cases, people may be allergic to the sterile fluid used during the procedure. This can cause symptoms such as rash, itching, and swelling.


HyCoSy test is a diagnostic procedure used to examine the condition of the uterus and fallopian tubes. If you are considering having a HyCoSy procedure done, it’s important to be aware of the risks and possible side effects.
