How long can you effectively keep my frozen sperm?
(more FAQ's below)

Sperm can be frozen indefinitely. There have been normal pregnancies from sperm stored frozen for 12 years. The efficacy of the freezing is questionable when it has been frozen for over 12 years. Each individual's sperm reacts differently to the freezing process. The result of the thawed test batch can give you some indication of how your sperm reacts to the process.
