Sperm freeze MFI

Lex

My husband has severe MFI as his count is so so low. He had an appointment yesterday to have a sample froze in case he doesn’t produce enough on egg retrieval day. The doctor called and said they got 6 yesterday and they will watch them for a few days to make sure they can survive a freeze and thaw. Does anyone have any experience with this? His morphology and motility is great it’s just his count. I’m worried we won’t have any eggs fertilize on ER day.
