We did ICSI because we had to but given the chance I would have tried straight IVF first. From what I have read (limited, because it just served to make me anxious and it was pointless to keep researching as I didn't have a choice in treatment) there may be a higher risk of birth defects associated with the process of ICSI. Every FS has a different opinion though so it's worth checking with yours.

My clinic also charges extra for ICSI so if yours does that may also be a factor for you.

Best of luck!
