I-29: Can Fresh Embryo Transfers Be Replacedby Cryopreserved-Thawed Embryo Transfers inAssisted Reproductive Cycles? A RandomizedControlled Trial

Background: Controlled ovarian stimulation (COS) has been shown to advance endometrial maturation and affect adversely implantation in assisted reproduction technology (ART) cycles. It has been reported that there is a better embryo-endometrium synchrony in frozenthawed embryo transfer (FET) cycles than fresh embryo transfer (ET) cycles. The Background of this study was to compare ongoing pregn...

Comparison of pregnancy rate between fresh embryo transfers and frozen-thawed embryo transfers following ICSI treatment

BACKGROUND The use of assisted reproductive technology (ART) is increasing in the world. The rate, efficacy and safety of ART are very different among countries. There is an increase in the use of intra cytoplasmic sperm injection (ICSI), single fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET). OBJECTIVE The objective of this study was to compare pregnancy rate in fresh ET a...

Comparison of clinical outcomes between fresh embryo transfers and frozen-thawed embryo transfers

BACKGROUND Advances in embryo culture technology and cryopreservation have led to a shift in in vitro fertilization (IVF) from early fresh or frozen-thawed cleavage embryo transfer to fresh or frozen-thawed blastocyst stage transfer. OBJECTIVE To compare the clinical outcomes of fresh embryo transfers and frozen-thawed embryo transfers. MATERIALS AND METHODS In this retrospective case contr...
