Fair sperm progression and IUI


I had an IUI last wednesday and my husband’s total motile sperm count (post wash) for the IUI was 14 million. His motility was 55% HOWEVER, what I am most concerned about is his “forward progression,” which came out as “slightly moving forward.” On a scale of 0-4 (0 being no sperm moving and 4 being rapid moving linear sperm), it was a 2 :grr:.

Anyone have success with an IUI where the forward progression was slow, meaning the sperm weren’t seen as “swimming” very fast? Do only “fast” moving sperm fertilize eggs or can the slow ones eventually make it as well? Sorry to ask such a technical sperm question, just looking for a little hope to be restored that this cycle wasn’t a total bust. Tiffany
