P-187: Poor Endometrium and Repeated IVF Failure: Is That Any Place for Modified Natural Cycle Frozen-Thawed Embryo Transfer?
Authors
Abstract:
Background: The objective of this study was to compare the pregnancy rate of Frozen-thawed Embryo Transfer (FET) on natural versus hormone replacement therapy (HRT) cycle endometrium, in patients with repeated IVF failure (RIF). Materials and Methods: In this observational study, the pregnancy rate after FET on natural endometrium in patients with RIF and previously poor endometrium (<7mm) on HRT (group 1, n=14) and patients with RIF with previously normal endometrium (group 2, n=42), comparing with patients with RIF and normal endometrium, in whom frozen-thawed embryos on HRT cycle were transferred (group 3, n=52), was analyzed. Results: The pregnancy rate in group 1 and group 2 was 35.7% (5 out of 14) and 42.2 %( 18 out of 42) respectively, in comparison with the pregnancy rate of group 3; 36.5% (19 out of 52). The abortion rate was not significantly different between groups. Conclusion: To sum-up, in this study it was concluded that modified natural cycle is comparable with HRT cycle under certain conditions.

full textFrozen-thawed embryo transfer cycles
In order to reduce the chance of multiple pregnancy during in-vitro fertilisation (IVF)– embryo transfer treatment, there is an increasing trend towards transferring a lower number of embryos. Surplus good-quality embryos are then transferred in frozen-thawed embryo transfer (FET) cycles. The first pregnancy after FET was reported in 1983.1 It has been estimated that in IVF programmes in which ...

BACKGROUND The aim of this study was to investigate the effect of natural cycle (NC) endometrial preparation for frozen-thawed embryo transfer (FET) in women with advanced endometriosis. MATERIAL AND METHODS This retrospective study included 179 patients with stage III-IV endometriosis who underwent 233 FET cycles at a tertiary care academic reproductive medical center between March 2011 and Au...

Cumulative pregnancy rate has been significantly increased since frozen-thawed embryo transfer was applied in ART cycles. This method has become an essential part of IVF/ICSI treatment. Luteal phase support has been proven to be associated with higher rate of live birth rate. Human chorionic gonadotropin (HCG), and progestrone have been successfully used for luteal phase support in ovarian stim...
