Nordic Cryobank/European Sperm Bank

Sperm Bank

The Nordic Cryo Bank, also called The European Sperm Bank, is situated in Copenhagen, Denmark and was started in 2004. Nordic Cryobank (NCB) initially distributed sperm through CCB in the US, but now they do not- sales are through our European Sperm Bank USA site. Check also California Cryobank donor numbers in the U.S. to see if the donor there is the same number is the same as yours (CCB only has had anonymous donors from NCB/ESB). Donor numbers are four digits and begin with a 7 for this sperm bank. Nordic Cryobank sells to clinics, and patients will get the donor id from the clinic if they ask for it. If possible, please post both the donor name and the donor number. People in the U.S. get donor numbers (they are also on CCB's donor list), and people from other countries get the alias donor name if they have bought via European Spermbank .
