no specific advice but wishibg the best for your friend. there are other girls on her who would be able to share if changing would help.
have they tried sonething like hm takibg vitamins etc?
Are they doing ICSI? (Where a normal looking sperm is selected for injection directly into the egg, rather than just putting it all together in a petri dish.)
With MFI that would be the usual plan, as far as I understand.
I would change clinic after 5 unsuccessful attempts, otr at least be sitting down with my FS to ask what they are doing and why it isn't working.
