Why can infertility happen for males after childhood cancer?
Chemotherapy
If you've had chemotherapy with certain drugs, your healthcare team will talk to you about your individual risk of infertility. The most common chemotherapy treatments to cause infertility are Ifosphamide, Cyclophosphamide, Procarbazine, Melphalan, Thiotepa, CCNU, and BCNU. Your level of risk depends on how much you've had.

- brain (affects your hormones)
Surgery
Surgery to your testicles or other reproductive organs can affect your fertility.

Should I use contraception after childhood cancer?
Make sure to use condoms - protect you and others from STDs. And, don't assume you will be infertile from your treatment!
Yes, it's important to use contraception! Don't think that just because you've had some of these treatments, you will be infertile. It's also important to use condoms to protect yourself from sexually transmitted diseases.
Will my children get cancer if I've had cancer treatment?
Some rangatahi who have had cancer worry that their treatment may cause health problems in their own tamariki (children). There is no evidence that this is the case. Except for some rare inherited cancers, there is also no evidence that your child will have an increased risk of developing cancer.
What if I had my sperm banked before treatment for childhood cancer?
If you had sperm banked before treatment, it is important to tell the sperm bank if your contact details change. They will contact you from time to time. If they have lost contact with you for 10 or more years, they may destroy your banked sperm.
