Background and purpose: In the past three decades with the advent of modern assisted reproductive techniques (ART) and transfer of fresh or freeze embryos into the uterus, pregnancy has resulted in many cases of infertility. The studies of authers were shown comparable gestational and perinatal outcomes in two methods and sometimes better outcomes in freezeembryo transfer. Material and methods: This case series study was done on pregnant women who underwent intracytoplasmic microinjectionand embryo transfer (ICSI-ET) at the infertility clinics in Sari city. Pregnancy and perinatal outcomes were evaluatedand compared in two transfer way, fresh embryo transfer (fresh-ET) and freeze embryo transfer (freeze-ET). Results: Male factors cause infertility in 199 cases (49.8%) and female factors cause in 92 cases (23%). In 53 cases (13.3%) both male and female factors contributed.The cause of infertility was unknownin 56 cases (14%). None of maternal and fetal complications of pregnancy had significant differences in this two embryos transfer methods.In the fresh-ET cycles, 5 patients (3.3%) were hospitalized due to threatened abortion versus 3 patients (1.2%) in freeze-ET cycles. There was no statistically significant difference in two methods about NICU admission and the need of respiratory support. Conclusion: In this study, we have demonstrated that gestational and perinatal outcomes in both embryo transfer methods, fresh and freeze ET were similar
