I asked about this in Zlin
http://www.crmzlin.cz/en/page/100.introductory-page/ and was very interested in doing it, but at that specific clinic they wouldn't give out any information about the donors, just that they were all Caucasian. No blood type, hair or eye color etc.
I have heard from some other women, though, that other Czech clinics will give out the information. If you're interested in a European holiday, it might be a great way to cycle. The prices are really low, can be under $1000.
Good luck.
