Based on a somewhat out-dated (2007) yet thorough comparison chart, I settled on my criteria:
- open identity option
- some reasonable limits to offspring per donor (***)
- will ship to home (exception for local cryobio)
- adult-photo preferred (exception for TSBC)
- full medical history available
- genetic testing
- excluded if negative comments.
As of now, I am sold on TSBC. I must pause to heartily thank the lesbian community for blazing trails and sharing their knowledge! I read a moving testimonial in favor of TSBC, which introduced me to the idea of slickness-integrity tradeoff. TSBC's non-profit status is a strong and notable endorsement along the same lines.
