Blastocyst transfer in frozen-thawed cycles
OBJECTIVE It is well known that fresh blastocyst transfer results in better pregnancy outcomes with a smaller number of transferred embryos compared with cleavage stage embryo transfer. However, in terms of frozen-thawed blastocyst transfer, only a few studies are available. We aimed to evaluate clinical outcomes of frozen-thawed embryo transfer (FET) with blastocysts. METHODS Retrospective a...
متن کاملFrozen-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 ...
متن کاملEffects of endometrial injury on frozen‐thawed blastocyst transfer in hormone replacement cycles
Aim To evaluate whether local endometrial injury would improve the pregnancy rates after frozen-thawed blastocyst transfer in cycles with hormone replacement. Methods Seventy-seven patients who were aged <40 years with a history of at least three unsuccessful embryo transfers and who underwent frozen-thawed blastocyst transfer during hormone replacement cycles between February and June, 2013 ...
متن کاملDelayed blastocyst development does not influence the outcome of frozen-thawed transfer cycles.
OBJECTIVE To compare the outcome of transfer of thawed blastocysts frozen on either day 5 or day 6 after in vitro fertilisation. DESIGN Cohort observational study. SETTING Tertiary assisted conception unit in London, UK. POPULATION Six hundred and forty-two consecutive nondonor programmed thawed blastocyst transfer (TBT) cycles. METHODS High-grade blastocysts were frozen on day 5 (n = 3...
متن کاملA retrospective study of single frozen-thawed blastocyst transfer
OBJECTIVE To study the clinical outcomes of single frozen-thawed blastocyst transfer cycles according to the hatching status of frozen-thawed blastocysts. METHODS Frozen-thawed blastocysts were divided into three groups according to their hatching status as follows: less-than-expanded blastocyst (≤EdB), hatching blastocyst (HgB), and hatched blastocyst (HdB). The female age and infertility fa...
