A 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...
متن کاملNavigation problems of ICSI or naive blastocyst can be solved with artificial blastocyst
Embryos have evolved a remarkable capacity to find implantation site. The impressive navigation ability of natural blastocysts may rely on highly sensitive signals arising from embryos and specialized signal processing strategies in the endometrium. Navigation capabilities may be compromised in ICSI embryos because of altered biochemical signaling. The design and delivery of artificial blastocy...
متن کاملSingle Day 2 embryo versus blastocyst-stage transfer: a prospective study integrating fresh and frozen embryo transfers.
BACKGROUND Whether extended culture allowing selection of embryos with high development potential has any advantage over cleavage-stage embryo transfer remains a matter of debate. Among the currently unsolved questions, the cumulative delivery rate resulting from fresh and frozen embryo transfers needs to be taken into account in both strategies. The aim of our study was, therefore, to compare ...
متن کاملThree blastocyst stage embryo transfer resulting in a quintuplet pregnancy.
High-order pregnancies are associated with high morbidity and mortality and the incidence is increased as a drastic complication of assisted reproductive technology. This case presents a high-order pregnancy achieved by transfer of three blastocyst stage embryos resulting in a quintuplet pregnancy including a monochorionic triplet. Following the selective termination of the monochorionic triple...
متن کاملBlastocyst 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...
