Background: Transfer of micro-Injected oocytes into fallopian tubes is an alternative procedure for IVF-ET with a similar success rate. This could be either done immediately after ovum pick-up microinjected oocytes intrafallopian transfer (MIFT) or aftera timeinterval zygote intrafallopian transfer (ZIFT). This studywas designed to compare the outcomes of the twoprocedures. Materials and Methods: The study population included 149 infertile patients who needed assisted reproductive technologies (ART) and fulfilled the criteria for transfer of oocytes into tubes. 2-5 injected oocytes were transferred intonormal fallopian tubeeitherimmediately (GroupA)or 24 hours later (Group B). Results:Atotal of63 (36.9%)pregnancies wereachieved .Therewere 33pregnancies inthe immediate transfer group and30 pregnancies in the delayed transfer group. No significant difference was found in the implantation rateand the clinical pregnancy rate. Conclusion: This study demonstrates that no difference could be observed in outcome between immediate and delayed transfer groups. Therefore, immediate transfer of microinjected oocytes into fallopian tubesor MIFT is the preferred method.
