Teenage and young adult cancers fertility preservation - sperm freezing: patient information

Do I need to use contraception?

While cancer treatment may affect your fertility, it is impossible to know for certain whether you can still get a partner pregnant. Some treatments can damage sperm, which could potentially affect a pregnancy if conception occurs during treatment. Therefore, it is vital to prevent pregnancy if you are sexually active during cancer treatment and for up to a year after your treatment ends.

It is equally important to practice safe sex to protect yourself and your partner from sexually transmitted infections (STIs). Using a condom during sexual activity is strongly recommended to ensure both your safety and your partner’s.
