Previously reported better fertilization rate after intracytoplasmic single sperm injection (ICSI) than subzonal insemination of several spermatozoa was confirmed in a controlled comparison the two procedures 11 patients. Intracytoplasmic carried out 150 consecutive treatment cycles infertile couples, who had failed to have fertilized oocytes standard in-vitro (IVF) or were not accepted for IVF because enough motile present ejaculate. A spermatozoon injected into ooplasm 1409 metaphase II...
Does conventional blastocyst morphological evaluation correlate with euploidy (as assessed by comprehensive chromosome screening (CCS) of trophectoderm (TE) biopsies) and implantation potential?A moderate relation between morphology CCS data was observed but the ability to implant seems be mainly determined chromosomal complement preimplantation embryos rather than developmental parameters conventionally used for evaluation.Combined improving methods cryopreservation culture, TE biopsy is...
The results and rationale of using testicular epididymal spermatozoa with intracytoplasmic sperm injection (ICSI) for severe cases male infertility are reviewed. A total 72 consecutive microsurgical aspiration (MESA) were performed congenital absence the vas (CAV) irreparable obstructive azoospermia. ICSI was used to obtain normal embryos transfer fertilization in 90% cases. overall rate 46% a cleavage 68%. pregnancy delivery rates per 58 37% respectively. cycle 33%. In many cases, no...
Does comprehensive chromosome screening (CCS) of cells sampled from the blastocyst trophectoderm (TE) accurately predict complement inner cell mass (ICM)? Comprehensive a TE sample is unlikely to be confounded by mosaicism and has potential for high diagnostic accuracy. The effectiveness aneuploidy limited technologies available in embryo. Combined with improving methods cryopreservation culture, biopsy CCS considered promising approach select diploid embryos transfer. study was performed...
Oocytes contain a maternal store of the histone variant MacroH2A, which is eliminated from zygotes shortly after fertilization. Preimplantation embryos then execute three cell divisions without MacroH2A before onset embryonic expression at 16-cell stage. During subsequent development, expressed in most cells, where it assembled into facultative heterochromatin. Because differentiated cells heterochromatin rich we investigated fate during somatic nuclear transfer (SCNT). The results show that...

BACKGROUND: It is not well defined whether the elapsed time after vasectomy has any influence on outcome of IVF–ICSI using epididymal sperm. We analysed retrospectively results 151 ICSI cycles in which sperm vasectomized men were used at different periods vasectomy. METHODS: Oocytes obtained a desensitizing ovarian stimulation protocol GnRH agonist association with recombinant FSH and HCG. Sperm retrieved by percutaneous aspiration. The split into three groups: ≤10 years (group 1, n = 47),...
This case illustrates the possibility of obtaining oocytes that fertilize and cleave normally after administration a second ovulatory dose human chorionic gonadotrophin (HCG) in 'empty follicle syndrome'. The present patient underwent ovarian stimulation with gonadotrophin-releasing hormone analogue (GnRHa)/menotropin for intracytoplasmic sperm injection (ICSI). After failure first oocyte retrieval, HCG was administered to trigger ovulation. A total 13 retrieved during procedure 11 good...
During the haploidization process, it is expected that diploid chromosomes of somatic cells will be reduced to haploid for generation artificial gametes. In present study, we aimed use enucleated mouse oocytes at germinal vesicle-stage (G2/M) as recipients are also synchronized G2/M stage haploidization. The reconstructed were then induced undergo meiosis in vitro and observed their nuclear morphology microtubule network formation various stages meiotic division. Following maturation, more...
Deriving histocompatible embryonic stem (ES) cells by somatic cell nuclear transfer (SCNT) and parthenogenetic activation (PA) requires fresh oocytes, which prevents their applications in humans. Here, we evaluated the efficiency of deriving ES from mature metaphase II (MII) immature I (MI) vitrified PA or SCNT, a mouse model. We successfully generated lines (MII MI) SCNT blastocysts. These expressed genes antigens characteristic pluripotent produced full-term pups upon tetraploid embryo...
This paper proposes the provision of quintuple-play services (high-speed wired data, voice, high-definition audio and video, wireless data security domotic applications) employing only orthogonal frequency division multiplexing (OFDM)-based radio-over-fiber (RoF) optical transmission in a deep fiber-to-the-home (FTTH) passive network. The different signals form RoF bundle comprising DVB-T for TV broadcasting, an LTE signal WiMAX supporting management home applications, UWB high definition...
