Not all cancers and cancer treatments cause infertility but some do so it is important to understand your individual risks. Infertility happens when you stop producing sperm or when your sperm is too damaged. Azoospermia is the medical name for having no sperm in semen.

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.
If you've had radiation to your pelvis, testicles, lower spine, brain (affects your hormones) or total body irradiation (TBI), this can affect your fertility.
Surgery to your testicles or other reproductive organs can affect your fertility.
This can happen after radiation or surgery to the brain.
You can have blood tests to check your hormone levels once you reach puberty. You can have a semen (sperm) analysis at any time to check if you are producing sperm. In some cases, sperm can recover up to several years after treatment.

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.
Some young people who have had cancer worry that their treatment may cause health problems in their own 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.
If you had sperm banked before treatment, it is important to tell the 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.
You can talk to your healthcare team about any of these issues in more detail.
