To evaluate the relationship between endometrial thickness during fresh in vitro fertilization (IVF) cycles and the clinical outcomes of subsequent frozen embryo transfer (FET) cycles.FET cycles using at least one morphological good-quality blastocyst conducted between 2012 and 2013 at a university-based reproductive center were reviewed retrospectively. Endometrial ultrasonographic characteris...

BACKGROUND The present study aims to compare which one has a better obstetric and perinatal outcome in singleton pregnancy, frozen embryo transfer (FET) or. in vitro fertilization treatment/intracytoplasmic sperm injection (IVF/ICSI)? METHODS MEDLINE, Google Scholar and the Cochrane Library were searched for the obstetric and perinatal outcomes in singleton pregnancy after assisted reproducti...

STUDY QUESTIONS What are the risks of adverse outcomes in singletons born after frozen-thawed embryo transfer (FET)? SUMMARY ANSWER Singletons born after FET have a better perinatal outcome compared with singletons born after fresh IVF and ICSI as regards low birthweight (LBW) and preterm birth (PTB), but a worse perinatal outcome compared with singletons born after spontaneous conception. ...

Abstract Background Vitrification has become the method of choice for cryopreservation human embryos and gametes. There are multiple commercial media, containing different combinations concentrations cryoprotectants, available vitrification warming procedures. The aim this retrospective study was to compare post-warming survival rate clinical outcomes cleavage stage vitrified/warmed using two m...

Aim To evaluate the use of frozen embryos on the outcome of assisted reproductive technology (ART), a retrospective study of the Japanese Assisted Reproductive Technology Registry data during the years 2007-2012 was conducted. Methods A total of 124 946 singleton neonates who reached term gestation following ART from 2007-2012, with 80 660 achieved through frozen-thawed embryo transfer (ET) a...

Transfer of frozen-thawed embryos is usually carried out in a natural cycle or in a programmed cycle in which the endometrium is exogenously stimulated following down-regulation of the hypophysis. To analyse the possibility that the programmed cycle for embryo transfer can still be hormonally manipulated without the use of gonadotrophin-releasing hormone agonist (GnRHa) we have conducted a pros...

Submit Manuscript | http://medcraveonline.com for 5 years due to polycystic ovary syndrome underwent some unsuccessfully low-complexity infertility treatments, then she underwent IVF/ICSI in October 2015. The patient opted for freezing-all embryos for subsequent transfer. In June 2016, two frozen-thawed embryos were transferred in the blastocyst stage. Twelve days after the embryo transfer, the...
