For some boys and young men with cancer, it is possible to store sperm before starting treatment. This is known as sperm banking. The sperm can be used later as part of fertility treatment to make a baby.

Research is being carried out to see whether it is possible to store eggs (ova), ovarian tissue or testicular tissue so that they can be used as part of fertility treatment. However, at the moment, these procedures are very experimental and not likely to lead to a successful pregnancy, so they are not discussed as part of this information. Your cancer doctor can give you information about these procedures if you want to know more about them.

It can be very distressing if you find that it is not possible to store eggs. There are specialist health care professionals who can help you cope - have a look at the resources section for more information.
