Sperm concentration
What is the minimum concentration for an IUI vial and a vial suitable for IVF/ICSI - before freeze?
The IUI vial we used was not even suitable for IVF as it the concentration was too low.
I now note that the donor has only IVF/ICSI vials available.
Is this indicative of issues with other IUI vials and now you can only sell them for IVF/ICSI use?
