ABSTRACT
Objective To compare the effect of three different fertilization modes of frozen-thawed embryos and blastocysts on the pregnancy outcome after thawed transplantation .Methods 3 586 cycles of frozen embryos transplantation (FET ) treatment in our center from January 2012 to December 2013 were retrospectively analyzed and divided into 3 groups according to the fertilization modes .The group A adopted the conventional in vitro fertilization (IVF) of frozen-thawed embryo transfer in 2 008 cases and blas-tocysts transfer in 954 cases .The group B adopted intracytoplasmic sperm injection (ICSI) of frozen-thawed embryo transfer in 361 cases and blastocysts transfer in 129 cases ;the group C was given early remedy intracytoplasmic sperm injection (r-ICSI) of frozen-thawed embryo transfer in 87 cases and blastocysts transfer in 47 cases .The recovery rate of embryo and blastocyst ,pregnancy rate ,abortion rate ,ectopic pregnancy rate were compared for determining whether the differences among the indexes existed . Results The thawing recovery rate ,pregnancy rate ,abortion rate and ectopic pregnancy rate in the three different fertilization modes of embryo and blastocyst had no statistically significant differences (P>0 .05) .Conclusion Compared with conventional in vitro fertilization and intracytoplasmic sperm injection ,early r-ICSI is one of effective treatment means .
