OBJECTIVE: To compare the clinical pregnancy and live birth results of fresh embryo transfer (ET) and selective frozen embryo transfer (sFET) in cohort of infertile patients aged between 18-42 years of age in single IVF center.
MATERIALS AND METHODS: In this retrospective cross-sectional study, the clinical and live birth results of 620 fresh embryo transfer cycles and 580 frozen embryo transfer cycles were investigated in Sisli Kolan International Hospital Fertility Unit between 2015-2018.
RESULTS: Age, BMI, causes of infertility, duration of infertility, ovulation induction protocols, the number of oocytes collected and the thickness of endometrium on the day of transfer were similar in the ET and sFET groups. More good quality embryos were obtained in sFET group. The clinical pregnancy and live birth rates were 71.04 % and 59.31 % in the sFET groups, and 56.77 % and 44.52 % in the ET group, respectively (p < 0.05).
CONCLUSION: Pregnancy, clinical pregnancy and live birth rates were higher in frozen embryo transfer cycles than in fresh embryo cycles. However, appropriate in vitro fertilization and embryo transfer methods suitable for each patient should be determined before choosing fresh ET or sFET treatment modalities.
