What ICSI achieves compared to conventional IVF is a higher rate of fertilization, but it does not necessarily make the cycle go better, that is, it does not achieve more pregnancies. What's more, some eggs may do better with conventional IVF than with ICSI, but this should be decided by the gynecologist together with the biologist.
Can ICSI be considered more effective than conventional in vitro fertilization?
