Hi, we are preparing for our first IVF ICSI cycle and our clinic asked if we wanted to freeze a backup sample of DH's sperm in case the one he produced on the day of retrieval wasn't good for some reason (we have MFI). It would cost us about £400 to freeze. The consultant said they prefer fresh sperm so they may never use the frozen backup one. Have any of you done this and do you think it's worth it?
