Fertility and Cancer Treatment

​​​​Cancer treatment can impact your fertility (ability to have a baby). You may not want to have children now, but you may want them later. Fertility preservation gives you the option of having your own children later on.

It is best to take action to preserve your fertility before receiving any type of cancer treatment. Sometimes cancer treatment can wait so that fertility preservation can happen first. There are some circumstances when it may not be safe to wait to start cancer treatment. Your health care team and the AYA Program can help you decide on the safest option for you.


What is Fertility Preservation?

For females, fertility preservation can mean:

  • freezing egg(s). Your eggs are saved so you can increase your chances of having your own biological baby in the future.
  • freezing embryo(s). Your egg is fertilized with sperm from a partner or a donor through in vitro fertilization. The fertilized egg forms an embryo (the first stage of a baby’s growth) before freezing.

The more eggs or embryos you freeze, the higher your rate of success at getting pregnant.

For males, fertility preservation means storing sperm that has not been exposed to cancer treatment in a sperm bank. You may decide to freeze more than one sample.
