The 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...
متن کاملI-38: Chromosome Instability in The Cleavage Stage Embryo
Recently, we demonstrated chromosome instability (CIN) in human cleavage stage embryogenesis following in vitro fertilization (IVF). CIN not necessarily undermines normal human development (i.e. when remaining normal diploid blastomeres develop the embryo proper), however it can spark a spectrum of conditions, including loss of conception, genetic disease and genetic variation development. To s...
متن کاملCumulative ongoing pregnancy rate achieved with oocyte vitrification and cleavage stage transfer without embryo selection in a standard infertility program
BACKGROUND Recent advancement of minimum volume vitrification methods has resulted in a dramatic increase in the efficiency of the process. The aim of this study was to estimate the cumulative reproductive outcome of a cohort of infertile couples undergoing ICSI and oocyte vitrification in restrictive legal conditions, where only a limited number of oocytes could be inseminated per cycle and em...
متن کاملCleavage stage versus blastocyst stage embryo transfer in assisted reproductive technology.
BACKGROUND Advances in cell culture media have led to a shift in in vitro fertilisation (IVF) practice from cleavage stage embryo transfer to blastocyst stage transfer. The rationale for blastocyst transfer is to improve both uterine and embryonic synchronicity and enable self selection of viable embryos, thus resulting in better live birth rates. OBJECTIVES To determine whether blastocyst st...
متن کاملInm-1: Blastocyst Culture: Advantages and Disadvantages
Both cleavage-stage and blastocyst-stage embryo transfer policieshave advantages and drawbacks.Potential advantages of blastocyst culture and transfer in human IVF include: i. synchronization of the embryo with the female tract leading to increasedimplantation rates; thereby, reducing the need for multipleembryo transfers, ii. assessment of viability of an embryobefore transfer. This can be ach...
