Lengthy But Limited

• The standard storage time for sperm to be frozen is 10 years. While this number may be surpassed if you wish, it is on average the longest you may choose to store it when you first make your donation.
  
  

Possibly Indefinitely

• Sperm can be frozen and stored at a sperm bank indefinitely. As long as the thawing process is done according to procedure, the sperm may be completely normally viable at any point after the freezing process. While they may have a standard beginning number, sperm banks do not have a set number of years that you are allowed to store sperm.
  
  

Bottom Line

• Because there is no set number of years that sperm banks will store your sperm you may keep it there indefinitely if you would like. Although the sperm's viability could be questionable the longer you leave it frozen, you may leave it there for as many years as you wish. Each sperm bank has slightly different variations on these rules and it is important to check each one before you choose.
