The best way to prepare for pregnancy is to wait three months after having a CT scan of the abdomen. It takes three months for a male sperm to develop and mature as it does for a female egg.CT has a certain degree of radiation, and men’s testicles are usually covered when they have a routine CT examination, which is permissible, but may cause some damage to the sperm and egg, so contraception is generally recommended for three months after a CT examination. If pregnancy is detected less than three months after the CT examination, termination of pregnancy is not recommended, because clinical data show that the radiation exposure dose of a single X-ray or CT examination is far below the minimum dose leading to adverse outcomes. It is recommended that obstetrics outpatient clinics should be consulted, and standardized obstetrics examinations should be carried out under the guidance of obstetricians, and decisions on whether to keep or keep the child should be made after careful deliberation.
