Some sperm banks, such as Fairfax Cryobank and Cryogenic Laboratories, refuse to give donors their donor numbers. Some people have lost paperwork, or can not get their donor numbers from their sperm banks and/or clinics. Other sperm banks and clinics have closed their doors.
If you need to look up a donor number, there is a website that you can try on: http://www.archive.org. Just type in your sperm bank's URL and it will list everything they have archived, including donor profiles. It's worth a try.
Additionally, we've scanned and uploaded some donor lists, originally provided to prospective parents by sperm banks. If you have a donor list that might be helpful to others searching, please email it to Wendy. Click on the links below to explore the lists.
