Medicated versus natural frozen embryo transfer for euploid embryos

Effect of Progesterone Supplementation on Natural Frozen-Thawed Embryo Transfer Cycles: A Randomized Controlled Trial

Frozen-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 ...

P-187: Poor Endometrium and Repeated IVF Failure: Is That Any Place for Modified Natural Cycle Frozen-Thawed Embryo Transfer?

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 H...

Establishment of Practical Embryo Transfer for Fresh or Frozen Embryos in Pigs

The most important benefit of embryo transfer (ET) in the swine industry is the ability to introduce new genetic stock as replacement herd animals with minimal risk of disease transmission and cost for transportation, in comparison with the transport of live animals. However, the commercial application of ET in the pig has been limited because of the need for surgical procedures for both the co...

Effect of Natural Cycle Endometrial Preparation for Frozen-Thawed Embryo Transfer in Patients with Advanced Endometriosis

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...
