Is Pregnancy After an HSG More Likely?


Question: Is Pregnancy After an HSG More Likely?
Answer:
You might have heard that there is an increased chance of pregnancy after an HSG. An HSG, or hysterosalpingogram, is a special kind of x-ray that involves administering an iodine dye via the cervix, into the uterus and fallopian tubes, and then taking x-ray pictures.

So, Is it true?

Perhaps. Whether or not an HSG can improve fertility is controversial. Some studies show a slightly increased chance of getting pregnant in the three months after the test, but the reason for the increased fertility isn't clear.

One theory is that the dye flushes out the fallopian tubes, clearing partial, minor blocks in some women. Another possibility is that the dye solution enhances the endometrium (the lining of the uterus) in some way, making it easier for an embryo to implant successfully. And yet another theory is that the dye solution somehow affects the area surrounding the ovaries, enhancing ovulation.

However, it's important to know that the increased chance of pregnancy after an HSG isn't that great. Doctors order an HSG for diagnostic reasons, and it's rarely used as a treatment itself.
