Cryos International

Sperm Bank

PLEASE CHECK/ POST UNDER SCANDINAVIAN CRYOBANK LIST TOO! Started in Denmark in 1987. Major Danish sperm bank. People who buy from both the Denmark bank and US bank could get a number or an alias. Cryos has started to recently begin assigning just numbers to US based donors again - these donors have absolutely no information provided about them beyond the very basics. People who order from Cryos Denmark can get extended profiles, alias names, numbers, etc. now for some donors. The US bank is no longer in New York, it is in Orlando, Florida. When the bank moved it shipped all remaining vials of US donors to the Denmark bank. People who are looking to buy those vials from the US can no longer do so as the bank does not ship to the US. People who want full genetic siblings should know to look for their US donor at the Denmark location. May 2021: Cryos now sells sperm in Gainesville, FL. Cryos ships sperm to over 100 countries.
