X-rays have an effect on pregnancy preparation, but the exact extent of the effect depends on the type of X-ray examination, such as fluoroscopy, chest X-ray or CT examination; X-rays have a certain amount of radiation on the human body, especially on the gonadal organs, which are sensitive to radiation, and too much X-ray radiation can easily affect the quality of sperm or eggs, which can lead to malformations or stillbirths. Therefore, for safety reasons, it is generally recommended that patients should wait 3-6 months after the X-ray examination before preparing for pregnancy, which is more appropriate and beneficial for eugenics. If a patient has had an X-ray or other tests that may affect pregnancy, it is important to inform the obstetrician and gynecologist in advance before preparing for pregnancy.
