CT for men affects having children. CT uses a high-energy X-ray machine to image the human body, and the data obtained is analyzed by computer for imaging, to obtain the tomographic anatomy of the human body and determine whether there are related diseases. Therefore, it is recommended that men should not consider having children within 3 months of CT, and should consider having children after 3 months. The maturation and aging cycle of semen is about 80 days, and 3 months has exceeded the normal maturation and aging cycle of sperm, so having children again at this time will not have any effect on having children, but try to avoid having children within 3 months. By the same token, you should not have children within 3 months after receiving X-ray examination, and consider having children after 3 months to avoid radiation exposure, which may lead to sperm malformation or increase the risk of embryo malformation.
