Hi cjayne and welcome to BellyBelly

Personally we didn't use ICSI but did use IVF for a long time. Success rates vary from clinic to clinic. Obviously at the end of the day it all just depends on that right little blastocyst. Success rates at clinic A may abysmal but you get a BFP first go, where as I might go to clinic B which has the best success rates in the country and never get a BFP. Some clinics may even base their success rates on a BFP not the take home baby rate ITMS? So their 'success' rate may be higher but not really the outcome you desire. It has been a long time since I was on the IVF rollercoaster but success rates then were around 45% per cycle (I think!) for my age group, under 30's.

Again number of blastocysts transferred depends on your IVF specialist. Our clinic only ever did 1. No more, never.

HTH. Best of luck with it. Fingers crossed for a quick journey
