Finding a donor

[ritara138]

we will be trying again in June and at this point they seem convinced that it's the sperm that's the issue. We may consider some alternatives such as freezing though we want to try again with my husbands sperm trying some of the methods they are recommeneding. and if that doesn't work again we'll be going the donor route. no one has mentioned how we do that. Anyone know how sperm donors are chosen?
thankyou, R
