How long does it take for fertility to return after cancer treatment in men?

It varies from person to person. According to the National Cancer Institute, changes to a man's fertility from cancer treatment may be temporary or permanent. When changes are temporary, fertility may return over time, but there is no single timeline that fits everyone.

How long it might take, if it returns at all, depends on the specific treatment, the dose and length of treatment, the man's age, the type of cancer, and other personal factors. Some treatments carry a higher risk to sperm and sperm-forming cells than others.

Because this is so individual, the National Cancer Institute lists it as a question to ask your doctor after treatment: "How long might it take for my fertility to return?" It also suggests asking about the chances that people who have your treatment are fertile afterward, and whether birth control should be used after treatment and for how long.

Your care team can give you the most accurate picture based on your treatment. A fertility specialist can also help you understand your options, including checking fertility after treatment.
