Hi all - My wife and I purchased 8 vials of Donor 18313 (for hopefully a sibling later on) and had our first unsuccessful IUI this month. We were surprised to see low motility numbers from the lab - only 4.83 mil. I see that he's had at least one successful pregnancy but want to see if anyone else has tried to use donor 18313 and had high motility numbers or a successful IUI. We really liked his profile but are worried about the motility numbers moving forward.
