Alright, at this point sperm can be frozen indefinitely. There’s no timeframe on how long you can freeze eggs or sperm. But particularly for sperm; sperm freezing can be indefinite and have the same quality once you go back to using the future, and the most important thing for men to remember is that what goes into the freezer is what comes out so if the sperm count is not healthy going in, then good chances it won’t be healthy coming out of the freezer after it’s been frozen. So if the sperm count is very good and healthy, long-term survival is indefinite and the chance of being successful with that sperm is the same as fresh.
