The neglected morula/compact stage embryo transfer.
BACKGROUND This retrospective study analysed the outcomes of 339 embryo transfers on either day 3 (n = 97) or day 4 (n = 242), and proposed a grading system for morula/compact embryos. METHODS The morula/compact embryo grading was based on: (i) the proportion of blastomeres undergoing the compaction process; (ii) the morphology of the compacted multicellular mass; (iii) the embryo quality on ...

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.

متن کاملThe cleavage stage embryo.
A precise embryo quality evaluation is of paramount importance to sustain a successful in vitro fertilization (IVF) program. In most IVF clinics around the world, this quality assessment relies mainly on the morphological evaluation of cleavage stage embryos. Embryologists should be able to correlate the features observed at the optical microscope with the implantation potential of each particu...
