Fairfax Cryobank

Sperm Bank

These numbers are the same as those at GIVF (Genetics and IVF). Sperm donors should be listed here, egg donors at GIVF. Fairfax supplies sperm to Can Am Cryo (Canada). They link to CLI on their website (and CLI links to Fairfax on their website), but they have their own donor numbers. They bought out a bunch of smaller sperm banks, including CLI, in 2002, but some of those banks are still operating in separate buildings and kept their old name. The donors are still separate from Fairfax numbers, so they don't have to be crossposted to the Fairfax list (but may need to be posted to another list--see the specific facility to see if something is mentioned in the heading).
