Sperm Motility - Slow Forward Progression Question

[Anonymous]

I just did a round of back to back IUIs. My husband's total motile sperm count (post wash) for the 1st IUI was 32 million and for the 2nd IUI it was 11 million. His motility was 54% and 42% 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 1 and 2.

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. TIA!
