X-rays refer to X-rays, and if a man has an X-ray once in a while, it usually does not affect his sperm. If X-rays are performed frequently, they can have an effect on sperm. X-rays are radioactive, and determining whether or not a man’s X-rays have an effect on his sperm needs to be determined on a case-by-case basis and cannot be generalized. Generally speaking, men who undergo X-ray occasionally will not have any effect on their sperm, nor will it cause any adverse reactions. However, if men undergo frequent X-ray examinations, it will have an effect on sperm. This is mainly because when men receive a lot of radiation exposure, it is easy to make the structure of sperm cells abnormal, resulting in malformed sperm. If a woman’s egg and deformed sperm combine to form a fertilized egg and successfully implant, it is more likely to result in poor development of the fetus and miscarriage of the pregnant woman. To summarize, X-ray examination is with certain radiation, so hospitals will use lead clothing to protect patients who need to do this examination, to reduce the harm it causes to the human body.
