Overview of the test

The fallopian tubes in a woman's body are channels for her eggs. The health of fallopian tubes and their connection with the ovary determine how well the female reproductive system functions. Fallopian tubes play a major role in determining the overall fertility of a woman. There are many ways to test for the health of the fallopian tubes. The most common tests are X-ray hysterosalpingography (HSG) and hysterosalpingo-contrast sonography (HyCoSy). These two types of sonography show you the structure and state of function of the fallopian tubes.

About the test 

HycoSy and HyfoSy are alternative tests for HSG. The HyfoSy test is an alternative because it reduces the chances of complications caused by X-ray radiation and iodine contamination. The HyCoSy/HyFoSy tests are safer than the traditional HSG test. The two are ultrasound-based techniques which help determine the health of fallopian tubes. The test shows if there are any abnormalities in the fallopian tubes. It determines whether the woman has any blockages in the fallopian tube, which contributes to infertility. Once the couple is sure that the male partner is not infertile, the woman may undergo the HyCoSy/HyFoSy test.

Preparing for the test

The process of the HyCoSy/HyFoSy test occurs through a series of chemicals and catheter devices. With the use of a clean intrauterine device, the process is possible. The test occurs mostly from day 5 to day 11 of a woman's period. The woman must prepare for a small invasion into the uterus by the device through the vagina. The process is handled by technicians and doctors, so you do not have to worry much about the preparation. However, make sure you choose the right kind of facility for the test.

What to expect from the test

Expect the process of HyCoSy/HyFoSy to take 10 to 15 minutes. It begins with a transvaginal scan and also includes cleaning the vagina and cervix with a speculum. The speculum is followed by an ultra-fine catheter for visualisation of the fallopian tube. Next, a foaming gel is injected into the fallopian tubes. The doctor visualises the structure of the fallopian tubes after that. Although it is an invasive procedure, do not expect any lasting pain.

Possible results of the test

There are two types of results that arise from the HyCoSy/HyFoSy. For example, when the foam gel is injected and spillage is seen in the tubes on both sides, the tubes are properly functioning. On the other hand, if there is no consistent spillage, there are some blockages in the tubes. The observation of possible blockages is a factor in infertility in women. In such cases, you seek the advice of a gynaecologist for further consultation on the treatment and management of female infertility.

Risk factors associated with the test

Some risks arise from the use of the HyCoSy/HyFoSy test. The doctor uses a kind of catheter or intra-tubal device to observe the lining of the fallopian tube. The HyCoSy/HyFoSy test helps you look at the internal structure of the tubes. However, the catheter can be very intrusive and also lead to infections. The HyCoSy and the earlier HSG method were more prone to infections and pain. The chances of iodine allergy also increase with exposure to iodine. However, the HyFoSy test is very safe for women and does not cause any complications.

When to see a doctor

You should see a fertility specialist if you suspect female infertility. If, as a couple, you see repetitive miscarriages, you should seek the help of a good fertility expert and obstetrician. After the HyCoSy/HyFoSy outcome, the expert doctor tells you how to conceive safely despite issues with the fallopian tubes. An experienced gynaecologist assists you with conception and taking the pregnancy to full term. Numerous health centres in India provide HyCoSy/HyFoSy tests for women. The Apollo Fertility chain is one such facility setup. You can visit the facility closest to you today.

The HyCoSy/HyFoSy is an advanced investigative test that deals with the internal health of the fallopian tubes. The test helps you know of the blockages in the fallopian tubes so that doctors get rid of the blockages and help in conception. After the HyCoSy/HyFoSy, the doctor ensures treatment for regular ovulation and a proper conception of the embryo

1. Is HyCoSy the same as HyFoSy?

No, HyCoSy is not the same as HyFoSy. However, the two tests are similar in technique and result.

2. Is the HyCoSy/HyFoSy painful?

The HyCoSy/HyFoSy is not entirely painless, but it is unpleasant for most women.

3. Does HyCoSy/HyFoSy help you get pregnant?

The HyCoSy/HyFoSy test helps you in diagnosing tubal blockage, which can guide the further course of action for pregnancy.

4. Can HyCoSy/HyFoSy improve fertility?

The diagnosis of tubal blockage via the HyCoSy/HyFoSy test may, in turn, help the doctor in advising you about ways to improve fertility.

5. Which is the better test, HycoSy or HSG?

The HyCoSy test is better than HSG because there is no radiation or iodine exposure.
