Concerns About Hysterosalpingography: Radiation Effects and Timing for Conception

Fallopian tubes

Hello Dr.
Lu,
I have a question.
My menstrual cycle started on July 8, and I underwent a hysterosalpingography (HSG) on the afternoon of July 11.
Is there any radiation residue left in the body after the HSG? If I were to conceive during these days, would it affect the fetus? Also, how many days after the HSG should I wait before having intercourse? My husband and I were together on July 13; will this have any impact? Thank you.

Many people have such concerns; however, according to clinical studies conducted abroad that followed up on many children born under these circumstances, no significant abnormalities or adverse effects were found when compared to other children after birth.

Hysterosalpingography (HSG) is a radiologic procedure used to examine the uterus and fallopian tubes, often to investigate infertility issues. Your concerns regarding radiation exposure and its potential effects on conception are valid, and I will address them in detail.

First, it's important to understand that HSG involves the use of X-rays to visualize the reproductive organs after a contrast dye is injected into the uterus. The amount of radiation exposure during an HSG is relatively low, and the procedure is generally considered safe. The radiation does not remain in the body after the procedure; it is a one-time exposure, and the body does not retain any residual radiation. Therefore, if conception were to occur shortly after the HSG, the radiation from the procedure would not pose a risk to a developing fetus.

Regarding the timing of conception, it is generally recommended to wait a few days after the HSG before attempting to conceive. This is primarily to allow any potential irritation or inflammation from the procedure to subside. While there is no strict guideline on how long to wait, many healthcare providers suggest waiting at least 48 hours to a week before engaging in sexual intercourse. This allows the body to recover and reduces the risk of any complications, such as infection.

In your case, since you had intercourse on July 13, just two days after the HSG, it is unlikely that the procedure would have any adverse effects on a potential pregnancy. However, if you have concerns about the timing or any symptoms following the procedure, it is always best to consult with your healthcare provider. They can provide personalized advice based on your medical history and current health status.

Additionally, it is worth noting that some studies suggest that HSG may actually enhance fertility for some women. The procedure can help clear out any mucus or debris in the fallopian tubes, potentially improving the chances of conception in the following cycles. However, this is not guaranteed, and individual results can vary.

In summary, while HSG does involve a small amount of radiation, it does not remain in the body and is unlikely to affect a future pregnancy. If you are concerned about the timing of conception after the procedure, it is advisable to discuss this with your healthcare provider for tailored guidance. They can help you navigate your fertility journey and address any other questions or concerns you may have.
