If you think your cancer or its treatment has affected your fertility, you may be able to have tests to find out if you are still able to have children.
Young women may find that it takes a while before their periods start again or become regular. Some types of treatment may be likely to cause an early menopause.
After treatment, even if young men are able to have erections and ejaculate, it may take a while before they start making sperm again.
After treatment, it can take some time to become clear whether your fertility is going to come back. It can be difficult to work out if any effect on fertility is temporary or permanent.
It can be hard to decide how long to wait after treatment, to have a test to see if you’re still able to have children. It’s important that you choose the right time for you as a person, although sometimes there may be medical factors to take into account.
