1. Will cancer treatment affect the fertility of a man or a boy?

Approximately six months after the completion of the treatment, men will undergo a spermogram that will present the information required related to levels, motility, and morphology of sperms, informing their fertile potential.

3. If fertility is not preserved, are there alternatives so that he can have children in the future?

Currently there are drug alternatives that can help to improve sperm production; however the results in men affected by chemotherapy and/or radiotherapy are not very satisfactory. When germinative cells are provenly dead, the alternative is to appeal to semen banks.

4. If the semen or the testicular tissue is frozen, is there a deadline for them to be used?

No, the semen and the testicular tissue do not have a deadline and they can be frozen for many years without prejudice.
