6 things you need to know about a Hycosy

baby3Dysfunction of the female reproductive organs is apparent in around 40% of infertile couples. Here at Complete Fertility Centre we offer patients a Hycosy screening test to look at a patient’s uterine cavity and fallopian tubes. If either are damaged then it may be difficult to get pregnant.

  1. What is a Hycosy procedure?

Hysterosalpingo-contrast-sonography (usually shortened to HyCoSy) is a safe and reliable outpatient ultrasound procedure.

A Hycosy is used to investigate infertility looking at the cavity of the uterus and the fallopian tubes. If either the cavity or the tubes are damaged, it may be difficult to become pregnant. The uterine cavity shape will be measured first. A contrast agent will then be injected into your uterus. If your tubes are not blocked then the agent can be seen passing through the fallopian tubes using ultrasound.

  1. What do I need to do to prepare?

It is important that there is no possibility of your being pregnant before the HyCoSy scan.  Please do not have unprotected intercourse from the first day of your period until after the examination. This procedure could disturb the implantation of an embryo. If there is a possibility that you are pregnant, the procedure will need to be postponed until your next menstrual cycle.

Patients need to have the results of an up to date Chlamydia test within the last year. Patients who have this test outside the Trust will need to contact their GP or sexual health clinic for a copy of their Chlamydia test results for our records.

The best time to perform a HyCoSy is approximately day 8 to day 18 of a regular 28-day (monthly) menstrual cycle (the first day of your period is counted as day 1). If you do not have regular periods please phone the Centre for advice. We are not able to do the examination if you are still bleeding from your period.

Patients should not wear perfume or strong deodorant on the day of their Hycosy.

When you are due to have the procedure you will be asked to partially undress and put an examination gown on.

  1. Do I need pain relief?

The level of pain experienced during the HyCoSy is variable. During the examination you may experience some discomfort and have a cramping sensation like a period pain.  It is wise to take two paracetamol about 30 minutes before your Hycosy procedure. No anaesthetic is required for this procedure.

  1. Where will it be?

At Complete Fertility Centre Hycosy’s are performed in our theatre.  A doctor and nurse will be in theatre with you.

  1. How is Hycosy performed?

It is not possible to see the tubes with normal x-rays or ultrasound, so a specialised examination must be done.

A hycosy procedure takes approximately half an hour. The first part of a hycosy is similar to a smear test. A vaginal speculum is gently inserted into your vagina to allow your doctor to visualise and take measurements of your uterus (womb), endometrium (lining of womb) and ovaries.

Under ultrasound guidance a thin tube (catheter) is then passed into the uterus through the neck of the womb (cervix). A small amount of saline is injected into the womb to distend the endometrial cavity and the contour and shape of the uterine cavity is assessed and any abnormalities, such as polps, fibroids, in the lining of the womb are also observed.

A contrast agent is then passed into the uterus and the fallopian tubes to assess the tubes. If the tubes are open, the fluid will be seen passing through the tubes on the ultrasound screen.

You can see a video of the hycosy procedure on our website.


  1. When do I get the results?

Your doctor or nurse performing the scan will be able to tell you the results of the examination once complete.  For any other tests you may have had performed, you will need to see the consultant to obtain these results.

We will provide you with a prescription for antibiotics that will prevent infection following your hycosy.

  2. I’m getting an appointment through the post for a hycosy, doctor said I can still have intercourse prior of the hycosy. I’ve not had periods for just under 2 years. Is that right to still be able to have sex as they say not to have it after your last period prior to hycosy?x

    1. It is extremely important to refrain from sexual intercourse (protected as well as unprotected) from the start of your period to the examination.

  3. I did had intercourse with my partner I totally forget about my Hycosy test is withing 7 days. Shall I go for test or wait for next month now?

    1. It is extremely important to refrain from sexual intercourse (protected as well as unprotected) from the start of your period to the examination. I suggest you call the Centre and let them know you have had intercourse.

  5. Hi, I had my hycosy done 10 days ago, experienced very painful cramps after and have been bleeding heavily every since. Is it normal to be bleeding so excessively? Should I be worried? I have PCOS so I thought that might factor into it but my period is always 5 days long and seems to be quite thick. Sorry for the details!!!

I have pcos .

        Am curious to know if there is anyone with same symptom and what could be the cause of it if? Pls help

  6. Hi I had a hycosy on the 16th it’s now the 21st and I’ve been getting bad cramps like I’m coming on and I feel bloated is that normal? Thanks

    1. It is normal to feel a little abdominal cramping or discomfort but this should be relieved by paracetamol and not last more than one day. If you have continued lower abdominal discomfort or pain you should see your GP as it might mean you have an infection and you need antibiotics.

    1. You might get some cramping pain for a few hours after the hycosy so you can take Paracetamol or your usual pain killers.

  7. Hi there I had my hycosy done in 11 of April nd my period finished on the 10 of April nd from yesterday I got brown chunky burning discharge when I go toilet is that normal ????

    1. If you experience offensive vaginal discharge you should go to see your GP as this may mean you have an infection and you may need antibiotics.

  8. Pain like labour contractions during, felt faint afterwards and sore for approx 1 week, take several sanitary/mat pads with you and someone to drive you home and get antibiotics from pharmacy before procedure if possible so you can go straight home to bed to rest up. Quite painful cramps in few days after. May need day or two off work if job involves standing up as seemed to make pain worse.

    1. The doctor will have asked you prior to the hycosy if you have had intercourse since your last period. If you had they would not do the hycosy due to the risk of pregnancy so this shouldn’t happen. The risk if pregnant is the possibility of flushing the pregnancy into the tubes.

    1. It delays your period because there’s fluid going into the tube and lining of the womb. Yes you can have unprotected sex afterwards.

      No it shouldn’t have delayed ovulation.
