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).

Xytex Corporation

Sperm Bank

Open since 1975. Offices in Augusta, Atlanta, and Newmarket, Ontario-supplier for Genesis Fertility Center in Canada (see that list also). According to Outreach Health Services' website (in 2008), http://www.donorspermohs.com, Outreach Health Services is the Canadian distributor for Xytex Corporation. Donor numbers should have three letters in front of the number (codes Xytex uses for hair and eye combinations, blood type, and height--first letter is for coloring: Dark Hair/Dark Eyes is A, Dark Hair/Light Eyes is B, Light Hair/Light Eyes is C, Light Hair/Dark Eyes is D, African American Donors are E. Second letter is for blood type: O+ is F, A+ is G, B+ is H, AB+ is I, Rh- is J. Third letter is height: Under 5'7" is K, 5;7" to 5'11" is L, 6' to 6'4" is M, 6'5" and taller is N). Numbers are only used one time with the donors so if you know the number part, you are most likely a match to that number if it is listed with letters (or different letters than what you have). Older donor numbers may have a D in front of them, but those are listed on here without the D. Their three letter code for the earlier donor numbers may have been different or may have been changed at one point in time by Xytex. (for example, an older number that used to be coded BFK was later changed to CGL). XYTEX AFFILIATES (found in Xytex archives): Xytex has satellite semen banks in the following locations: Florida Institute For Reproductive Medicine, (904) 399-5620, Jacksonville, Florida; Genesis Fertility Centre (604) 879-3032, Vancouver, British Columbia, North Carolina Center for Reproductive Medicine, (919) 233-1680 Cary, North Carolina; Pacific Reproductive Services, (415) 487-2288, San Francisco, California; Reproductive Health Associates, (813) 572-5300, Clearwater, Florida; Southeastern Fertility Center, (803) 881-3900, Mt.
