Are there differences in embryo quality or pregnancy rates between ICSI and non-ICSI embryos?
There appears to be no difference in the overall embryo quality achieved with ICSI embryos when compared to non-ICSI embryos. Similarly, no difference in pregnancy rates has been shown between ICSI embryos and non-ICSI embryos. Although unproven, there is a belief among many infertility specialists that ICSI may increase embryo yield from a given number of eggs recovered, which has contributed to the increase in ICSI procedures.
