Well, we actually didn't do any tests. Our known donor is a long time friend, married for 25+ years and they are about as trust worthy as someone could get. We knew there was nothing to worry about, so we chose not to pursue any testing. Of course, that's a chance we took and not all might feel comfortable with that. He did get a semen analysis done before we started just to make sure there weren't any issues with his swimmers. As for exposing the sample to air, as far as I know, it doesn't really matter. I remember when we did
IVF years ago with
DH's sperm, I asked our urologist how they store sperm samples and such before the procedure, and he said they just leave them sitting open out on the counter! So, donor simply gives a sample in a clean container and then we used an oral syringe to "inject" it as close to my cervix as possible. Hope that helps. I'm sure there are others here who might be able to tell you more. Unfortunately for
us, our positive
HPT last week was a bust. It was a chemical pregnancy and I started my period a couple days later. So, we'll be back trying again soon. Good luck with whatever you decide.
