I don't know a lot about sperm banks, but I don't think it's random. They give you a book that tells you the physical traits and other characteristics of the donor, and you select from that. I understand your concerns, but there are a lot of women who have babies through sperm banks, so your child wouldn't be the only one out there. And, of course, as you mentioned, there's also adoption. Every kid comes with issues to deal with. You just have to be able to deal with them and offer a lot of support. I think you can do that.
