Blastocyst development rate impacts outcome in cryopreserved blastocyst transfer cycles.
OBJECTIVE To assess cycle outcome among day 5 and day 6 cryopreserved frozen-thawed blastocyst embryo transfers (FBET). DESIGN Retrospective cohort study. SETTING Military-based assisted reproduction technology (ART) center. PATIENT(S) One hundred seventy-two nondonor, programmed cryopreserved embryo cycles. INTERVENTION(S) Fully expanded blastocysts on day 5 were cryopreserved on day 5...
متن کاملImportance of Blastocyst Morphology in Selection for Transfer
Prolonged cultivation of embryos to the blastocyst stage has become a routine practice in the human in vitro fertilization program (IVF) since 1999, when the first commercial sequential media were developed. The culture systems have been improved many times and today most of the blastocyst culture media enable the embryos to reach the blastocyst stage in more than 50% of cases (Gardner et al., ...
متن کاملThe effect of pronuclear morphology on embryo quality parameters and blastocyst transfer outcome.
BACKGROUND Embryo quality may be accurately assessed as early as the pronuclear zygote phase, as shown in recent studies. However, it is not known whether good quality zygotes are destined to become good quality cleavage stage embryos and blastocysts. METHODS In this retrospective study, 86 intracytoplasmic sperm injection-embryo transfer cycles were studied where each available embryo was sc...
متن کاملPrediction of clinical pregnancy in vitrified-warmed single blastocyst transfer cycles by pre-freeze morphology
BACKGROUND The selection of blastocyst warmed for transfer is based on pre-freeze morphology in vitrified-warmed single blastocyst transfer cycles. But, it is controversial which parameter of blastocyst morphology most closely related to the clinical outcomes. OBJECTIVE To estimate the effect of blastocoele expansion, trophectoderm (TE) morphology grade, and inner cell mass (ICM) morphology g...
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...
