Chances of Getting Pregnant After an HSG (Hysterosalpingogram) Test

An HSG test

Childbirth is one of the greatest joys in life. Ask any parents and they will affirm this feeling. The feeling of holding your newborn baby in your arms for the first time is simply amazing. Euphoria is the word that best describes those tender moments, and your child is sure to bring a lot of happiness in your life.

However, some couples are affected by infertility, which means that they are unable to conceive and get pregnant even after trying repeatedly. The causes of infertility are many, either the problem could be in a man, woman, or the lack of compatibility between the two. There are many treatment options for infertility and their degrees of success varies. One such treatment option is the HSG.

Can You Get Pregnant After an HSG Test?

In the HSG test, a dye, usually iodine, is injected into the uterus of the woman via the cervix and then X-ray images are taken. The dye reaches the fallopian tubes and provides clearer pictures to the doctor. This enables them to pinpoint the cause of infertility with greater accuracy. If there are any injuries or blockages occurring in the tubes, it shows up in the images taken afterwards. This makes it easy to find the reason for your infertility, and treat it accordingly.

While the HSG is primarily for diagnostic purposes, it has been observed that the number of natural pregnancies after HSG tests is higher in infertile women. The pregnancy rate after an HSG test is believed to be around 2 to 3 times higher than those infertile women who have not undergone this test before. The test itself is not a treatment for infertility; it is done to merely understand the reasons for infertility. However, it is a fact that a lot of infertile women got pregnant after the test was done, the exact reasons are unknown, though. Getting pregnant after the HSG, therefore, may simply be a coincidence, or due to some unknown reason in the procedure of carrying out the test. While HSG tests are not a treatment for infertility in any way, infertile women have a greater chance of getting pregnant after conducting this test. Therefore, it is definitely worth a shot.

HSG Test with a Water-Based or Oil-Based Contrast

A part of the test involves injecting dye into the uterus of the woman via her cervix. This is done so that the X-ray becomes clearer, and the doctor can identify any potential harm or injury that has occurred within the cervix. The technician will be able to see the uterine shape much more clearly, after injecting the dye into the uterus. However, there is another function for this contrast, it is tubal flushing. Tubal flushing means that the dye injected also does the job of clearing any blockages on the way to the fallopian tubes, making it easier for sperm to swim over to the ovum. This helps the sperm fertilize the egg and increases the chances of pregnancy. If tubal flushing is carried out as a therapeutic measure, there is no need to take the X-ray afterwards. Tubal flushing can be carried out either with water-soluble, oil-soluble, or combined contrasts.

In the case of using water-soluble or combined contrasts, it was found that there was no marked improvement in the chances of the woman getting pregnant. However, using the oil-soluble contrast did result in a high probability of fertilization. Couples who had undergone this procedure, their odds increased by around 25%.

However, you might have a few doubts about the health of your uterus while undergoing this procedure:

1. Can X-Ray Affect Eggs?

The X-rays do not ever affect the eggs in any way, as the eggs are always in a state of maturation arrest before the fertilization occurs. When the X-ray procedure is carried out, there is very less radiation that passes through the body of the female and it does not damage the eggs in any way, nor does it harm the growing foetus.

2. Can the Dye Harm the Eggs or Embryo or the Foetus?

The dye may harm the foetus if injected during the pregnancy. However, it does not harm the egg or the embryo in any way. The dye is also cleared out of the uterus quickly so that no harm will occur to the foetus that may be present in the uterus at the time of the HSG test.

Why Does an HSG Test Increase Your Chances of Pregnancy?

The process of injecting a dye into the uterus of the woman is meant to help in getting clearer X-rays, but it can even contribute to fertilization. When the ink moves to the fallopian tubes, it removes any blockages which may have occurred in the path and clears the way for the sperm to reach the fallopian tubes. This is called tubal flushing and it can help greatly in increasing the chances of conception.

How Long Will it Take to Get Pregnant After an HSG Test?

It has been found that the chances of conception occurring were increased by around 25% in couples for up to three months after the test was conducted. Therefore, couples will have to try to get pregnant for 3 months after the test in order to be successful.

HSG tests are meant to be diagnostic tools to help doctors understand the problem in a woman. However, the injected ink can clear any blockages within the uterus to make an easier path for the sperm to reach the ovum. Therefore, tubal flushing is definitely worth a shot for couples who are trying to get pregnant.
