This study sought to evaluate the clinical outcomes of within the extended embryos sub group, compaction stage embryo transfer to that of blastocyst-embryo transfer in human in vitro fertilization- embryo transfer (IVF-ET). A total of 136 patients, fresh IVF-ET cycles were analyzed between 2012 and 2014; 79 cycles of compaction stage transfer and 57 of blastocyst transfer. There is no significant difference was observed between the compaction stage embryo transfer and blastocyst stage embryo transfer with respect to the female age (30.6+3.2 and 30.7+4.5) and the number of oocyte retrieved. This study has shown that compaction stage embryo transfer can be offered along with the other programs as it is found to yield good clinical pregnancy rates which are equivalent to the blastocyst transfer results.
