These are very good questions, since my DH and I are doing DIUI in february thought maybe I could help a little.
do you have to take any psychological class if you use a donor sperm for IUI? We don't have to take any classes on it.
Which sperm bank did you choose and why? I like European Sperm Bank My RE gave us her top 3 sperm banks she likes to use, and we are currently looking through donors and comparing the ones we like the most, so far, our top running bank is Midwest Sperm Bank.
How long did it take you to get pregnant? can't answer this one yet
Did you use any medication/ trigger shot? We do not have to use any medication, or a trigger shot, b/c I have no issues.
Did you do the IUI at your OBGYN ? Our RE is doing our IUI.
