Does X-ray exposure damage oocytes?


Hello, doctor.
I have been infertile for over two years with no obvious cause.
After undergoing in vitro fertilization (IVF), I found out that my egg quality might be poor, resulting in a low fertilization rate.
I plan to arrange an intrauterine insemination (IUI) procedure next cycle, but due to recent recurrent bladder infections, my urologist has scheduled an intravenous pyelogram (IVP) during the first few days of my menstrual cycle, which requires five abdominal X-rays.
I would like to ask: 1.
Will taking X-rays harm the egg cells, reducing the chances of pregnancy or increasing the risk of miscarriage if I do become pregnant? 2.
Can I still arrange for the IUI procedure during this cycle? (I really don't want to miss any opportunities...) Thank you!

Hello, a small amount of X-rays will not harm the oocytes and is not related to a decrease in pregnancy rates or miscarriage.
Wishing you good health.

When considering the impact of X-ray exposure on egg quality and pregnancy chances, it is essential to understand the nature of X-rays and their effects on human biology, particularly in the context of reproductive health.

Firstly, the amount of radiation exposure from a standard X-ray is relatively low. Medical professionals have established guidelines to ensure that the benefits of imaging outweigh any potential risks. In the case of a typical abdominal X-ray or an intravenous pyelogram (IVP), the radiation dose is minimal and is not known to cause significant harm to egg cells (oocytes). Research indicates that low levels of radiation do not adversely affect the quality of eggs or the likelihood of conception.
1. Impact on Egg Cells and Pregnancy Chances: The concern about X-ray exposure damaging egg cells is understandable, especially for individuals trying to conceive. However, studies have shown that the radiation levels from diagnostic X-rays are not sufficient to cause chromosomal damage or mutations in egg cells. Therefore, it is unlikely that undergoing an X-ray examination would lower your chances of becoming pregnant or increase the risk of miscarriage once pregnancy occurs. The eggs are typically in a resting state during the menstrual cycle, and the exposure to low levels of radiation does not interfere with their viability or the fertilization process.

2. Timing of IUI Treatment: Given that you are planning to undergo an intrauterine insemination (IUI) procedure, it is crucial to consider the timing of the X-ray in relation to your ovulation cycle. Since the X-ray is scheduled for the days when your menstrual cycle is just beginning, it should not interfere with the IUI process. In fact, many fertility specialists would not recommend postponing IUI solely due to a scheduled X-ray, especially when the radiation exposure is minimal. It is always advisable to communicate with your fertility specialist about any concerns you may have regarding the timing of procedures and tests.

In summary, the consensus among medical professionals is that the radiation from a few X-ray images, such as those taken during an IVP, is not significant enough to affect egg quality or pregnancy outcomes. If you have been trying to conceive for over two years and are considering IUI, it is essential to proceed with your plans while ensuring that you maintain open communication with your healthcare providers. They can provide personalized advice based on your specific medical history and fertility challenges.

Additionally, if you have ongoing concerns about your egg quality or fertility, it may be beneficial to explore other diagnostic tests or treatments that could provide more insight into your reproductive health. Factors such as age, hormonal balance, and overall health can also play significant roles in fertility, and addressing these can improve your chances of conception. Always feel empowered to ask questions and seek clarity from your medical team regarding any procedures or treatments you are considering.
