Abstract

Along with methods of assisted reproductive techniques frozen embryos transfer methods are growing, although fresh embryo transfer course has always been the case of focus. Due to the fact that few studies have compared the two methods in the field of embryo transfer, the aim of this study was to compare the outcomes in fertility between these two transfer techniques. Materials & Methods: This semi clinical trial study included 215 patients, who received conventional ICSI treatment in Kosar infertility center of Motahari University Hospital, Urmia Iran, 2011-2013. Totally, 152 patients received fresh embryo and 63 patients received frozen ones. Results: Biochemical and clinical pregnancy rate were higher in frozen vs. fresh embryo transfer (57.1% vs. 40.3%; P=0.016). Clinical pregnancy rate was higher in fresh vs. frozen embryo transfer (50.8% vs. 34.9%; P= 0.003). The incidence of abortion rate before appearance of fetus heart (6 weeks) was similar in both groups (P=0.993) and the incidence rate of abortion before 20 weeks was higher in fresh vs. frozen embryo transfer (19 % vs. 17.1 %; P=0.0.144). Rate of twine, triple, multiple pregnancy and ectopic pregnancy were not statistically significant between two groups. Conclusion: Frozen vs. fresh embryo transfer increases chemical and clinical pregnancy outcomes and decreases rate of abortion before 20 weeks
