Donor without pregnecy

I'm new to the bank and forum but am following this post. My wife and I are currently in search of a donor and most of our "favorites" do not have reported pregnancies. In the back of my mind, I keep saying 1 of 3 things. 1. The families using this donor were not diligent and did not report confirmed pregnancies/births. 2. This donor is newish and hasn't had any confirmed. or 3. This donor isn't popular and hasn't been used. All are ver valid but still do not make the "NO" any less of an NO. Hopeful to hear some experiences.

So we narrowed down our choices and I called the bank to ask a few questions. The lady I spoke with was so helpful and it put our minds to ease. Ironically both of our top choices are BRAND new donors - hence the no confirmed. Our number 1 choice became available in February (he has limited available due to being so new, only 7 but is still active and has a few pending release) and our 2nd choice March (he has great availability however)! What are the odds? She said you're guaranteed 10mil a vile with IUI but so many factors plan a role so you could so right as well, infertility affects so many women.

I say call and ask about the donor(s) you're contemplating. They are all really helpful.
