Inm-5: Outcomes of Human Vitrified Embryos Transfer
The techniques of cryopreservation let embryos which cannot be immediately transferred to the patient be stored for future use. The first successful pregnancy after transfer of cryopreserved human embryos was described in 1983 by Trounson et al. and the first birth after cryopreservation was later reported in 1984 by Zeilmaker et al.). The technique has rapidly been applied in most in-vitro fer...
متن کاملThe morphology of human pronuclear embryos is positively related to blastocyst development and implantation.
Human embryos are selected for transfer using morphology at the cleaving and blastocyst stages. Zygote morphology has been related to implantation and pregnancy. The aim of this study was to relate pronuclear morphology to blastocyst development. Zygotes were scored according to distribution and size of nucleoli within each nucleus. Zygotes displaying equality between the nuclei had 49.5% blast...
متن کاملMicroarray analysis reveals abnormal chromosomal complements in over 70% of 14 normally developing human embryos.
STUDY QUESTION What are the aneuploidy rates and incidence of mosaicism in good-quality human preimplantation embryos. SUMMARY ANSWER High-level mosaicism and structural aberrations are not restricted to arrested or poorly developing embryos but are also common in good-quality IVF embryos. WHAT IS KNOWN ALREADY Humans, compared with other mammals, have a poor fertility rate, and even IVF tr...
متن کاملEfficient reproduction of cynomolgus monkey using pronuclear embryo transfer technique.
One of the technical bottlenecks in producing nonhuman primate models is that current assisted reproductive techniques, such as in vitro culture and frozen conservation of multicell-stage embryos, often result in poor embryo quality and subsequently lead to low birth rates. We investigated whether pronuclear embryo transfer can be used as an effective means for improving pregnancy and live birt...
متن کاملBio-electrosprayed multicellular zebrafish embryos are viable and develop normally.
Bio-electrosprays are rapidly emerging as a viable protocol for directly engineering living cells. This communication reports the bio-electrospraying of multicellular organisms, namely zebrafish embryos. The results demonstrate that the bio-electrospray protocol fails to induce any embryological perturbations. In addition to analysing overall embryo morphology, we use transgenic embryos that ex...
