Sperm-induced oocyte activation in the rhesus monkey: nuclear and cytoplasmic changes following intracytoplasmic sperm injection.
Intracytoplasmic sperm injection (ICSI) has increased the potential of the assisted reproductive technologies to propagate mammalian species and has provided an opportunity for research into cell cycle control and the mechanisms involved in sperm-induced oocyte activation. We have investigated the efficacy of ICSI in the rhesus monkey, the mechanism of fertilization following sperm injection an...
متن کاملOptimal Timing for Oocyte Denudation and Intracytoplasmic Sperm Injection
Objectives. To analyze the impact of oocyte denudation and microinjection timings on intracytoplasmic sperm injection (ICSI) outcomes. Study Design. We included ICSI cycles with the following parameters: rank 1 or 2, female age <36 years, male factor infertility, long protocol using GnRH agonist and rFSH for ovarian stimulation, and use of freshly ejaculated sperm (n = 110). Several ICSI parame...
متن کاملEndometriosis Affects Oocyte Morphology in Intracytoplasmic Sperm Injection Cycles?
OBJECTIVE To identify associations between presence of endometriosis and oocyte defects, embryo developmental potential, and cycle outcomes. METHODS This study looked into the impact of endometriosis on oocyte and embryo quality, and blastocyst formation probability. Endometriosis was also correlated with cycle characteristics. In order to avoid age-related bias, in the first analysis only pa...
متن کاملOocyte morphology does not affect fertilization rate, embryo quality and implantation rate after intracytoplasmic sperm injection.
In this study, we compared the fertilization rate and embryo quality after intracytoplasmic sperm injection (ICSI) as they relate to oocyte morphology. A total of 654 ICSI cycles yielding 5903 metaphase II oocytes were observed. The oocytes retrieved in these cycles were divided into (i) normal oocytes, (ii) oocytes with extracytoplasmic abnormalities (dark zona pellucida and large perivitellin...
متن کاملArtificial oocyte activation in intracytoplasmic sperm injection cycles using testicular sperm in human in vitro fertilization
OBJECTIVE Artificial oocyte activation (AOA) is an effective method to avoid total fertilization failure in human in vitro fertilization-embryo transfer (IVF-ET) cycles. AOA performed using a calcium ionophore can induce calcium oscillation in oocytes and initiate the fertilization process. We evaluated the usefulness of AOA with a calcium ionophore in cases of total fertilization failure in pr...
