Does radiation affect fertility?

It can. Radiation can affect fertility. The most sensitive tissue is the early developing embryo, so there is significant risk in early pregnancy. Affecting eggs and sperm requires much higher doses of radiation. Environmental exposure is best avoided, and clinical exposure should be minimized with shielding. Discuss any concerns with the prescribing physician.
Yes. The effects of radiation on infertility depend on the dose, the location, and the number of treatments. It affects both male and female infertility. Anyone about to undergo radiation therapy should have a consultation with a fertility specialist prior to treatment. Low levels of radiation in tests like a ct scan is not harmful unless multiple tests are performed, which is very unusual.

Radiation. Radiation therapy will only affect fertility if the testicles or ovaries receive treatment. Therefore this is usually only an issue for patients with pelvic cancers. For women these most commonly include cervix cancers and for men testicular cancer. Patients of both sexes can have issues if radiation is needed for lymphomas in the pelvis, some sarcomas, or even rectal or bladder cancers. For some of these cancers surgeries or chemotherapy are also given that can have effects on fertility. This can also be an issue in many types of childhood cancers. There are a number of things that can be done to try to preserve fertility when pelvic radiation is needed. Modern radiation techniques like imrt and image-guided treatment can sometimes minimize dose to the reproductive organs. Sometimes special shields can be used to protect the testicles from scatter radiation. Sometimes the ovaries cane be surgically moved to a different placement in the pelvis where they can be more easily blocked from the radiation dose. Men can also sperm bank and there freezing or transplantation of ovarian tissue to another place in the body (like under thesis on the arm) is being studied at some institutions. Your radiation oncologist should address fertility issues with you during the consultation and subsequent visits. It is also important to discuss potential hormonal changes and/or changes in sexual function that might result fom radiation.
Yes. Exposure of gonads (testes and ovaries) to radiation can make you sterile. People who undergo radiation often have cancer and receive a lot of chemotherapy which can affect their fertility also. So cancer patients have a higher risk of infertility even if the gonads are not exposed to radiation. Radiation can also be a hazard if you are a radiological worker but safeguards are in the workplace.
