Programmed versus natural frozen embryo transfer: which is the best nest?

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...

Methods of Teaching Electrocardiogram: Which One Is the Best?

Introduction: There are many methods for teaching ECG interpretation, but deciding on the best method is yet to be discussed. The purpose of this research was to examine teaching methods for ECG interpretation and introduce the most effective ones. Methods: This systematic review was conducted by searching through scientific databases of PUBMED, Science Direct, SID and IranMedex. Papers publish...

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 ...

Human chorionic gonadotropin-administered natural cycle versus spontaneous ovulatory cycle in patients undergoing two pronuclear zygote frozen-thawed embryo transfer

Objective To compare human chorionic gonadotropin (HCG)-administered natural cycle with spontaneous ovulatory cycle in patients undergoing frozen-thawed embryo transfer (FTET) in natural cycles. Methods In this retrospective cohort study, we analyzed the clinical outcome of a total of 166 consecutive FTET cycles that were performed in either natural cycle controlled by HCG for ovulation trigg...
