What are the side effects of hysterosalpingography (HSG)?
Disease description:
I’ve been trying to conceive for a year without success. A friend suggested I go to the hospital for a hysterosalpingography (HSG) to check whether my fallopian tubes are functioning properly. What are the potential side effects of HSG?

Dr. Chen Zhe
The side effects of hysterosalpingography (HSG) are generally minimal, though rare complications—such as vasovagal reaction (also known as “post-abortion syndrome”) or allergic reactions—cannot be entirely ruled out. During the procedure, some women may experience an allergic reaction to the contrast medium, manifesting as pain or other symptoms. Mild vaginal bleeding may occur for a short period after the procedure but typically resolves spontaneously. Since HSG involves X-ray imaging, there is potential—albeit small—for radiation exposure to affect fetal development; therefore, it is recommended to wait at least three months before attempting pregnancy.
