When should I ask about fertility preservation before cancer treatment?

At the first appointment, before anything else about the subject is settled in your own mind.

Fertility preservation almost always has to happen before cancer treatment begins. The window is often measured in days. Some people wait until they have worked out what they believe. Others wait until they feel ready to think about children. They often find the calendar has made the decision for them.

Ask for the referral first. You can decline any option after you know what the options are, and declining costs you nothing.

Three sources are worth using together. Your oncology team can say what your treatment is likely to do to fertility. They can also say how much time there is. A fertility specialist can say what is possible in that time. If Catholic teaching matters to your decision, ask for a hospital ethics consultation. You can also call the National Catholic Bioethics Center. Either one can take up your own situation, and both are free.

If you are treated at a Catholic facility, note that it will not provide IVF-based preservation. Under the 2025 Directives, staff there may not refer you elsewhere for it. They must still help you move your care safely to a provider you choose. Find an outside clinic early, and ask for records to be sent promptly.
