The only possible way to do this is by means of sperm banking. Today's freezing methods allow us to store sperm and reach almost the same success rates as if it has not been frozen previously. Thanks to the cryoprotectants and ultra-rapid freezing methods used, sperm can be kept alive outside the body, without being damaged and with almost the same fertilization potential.
