Anybody who presents with the possibility of a testicular cancer, we actually counsel and advise them to bank their sperm. Unless of course, the patient has no desire to father children. But even in those cases I still recommend the patients actually bank their sperm.
The reason is that many of the treatments that we have for testicular cancer, whether it's surgery, chemotherapy or radiation therapy, can all affect a patient's fertility, either in the short term or the long term. With many of these treatments the fertility can return over time. However, it's not guaranteed and we don't know how long it's going to take.
For those reasons, because there are a lot of unknowns, I usually tell me patients to try to bank their sperm. Now what that involves is going to a facility called a sperm bank or an assisted reproduction center and donating your sperm or getting a sample of the sperm. It then gets frozen down and preserved by that bank.
You basically pay a certain fee on an annual basis to preserve that sperm there until there's a time when you need it. But in general, we counsel many of our testicular cancer patients to perform sperm banking for these reasons.
