P-56: Artificial Oocyte Activation Alone Intra Cytoplasmic Sperm Injection in Men with Severe Semen Parameters
Background Failed fertilization occurs 1-3% in the infertile couples. Failure of oocyte activation (OA) is mainly attributed to failed fertilization. ICSI alone artificial oocyte activation (AOA) is only treatment approach for these individuals. Three procedures are introduced for AOA: chemical, mechanical and electrical. Most of the clinical Centers have commonly used ionomycin for activation ...
متن کاملSperm-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 کاملRelationship between Potential Sperm Factors Involved in Oocyte Activation and Sperm DNA Fragmentation with Intra-Cytoplasmic Sperm Injection Clinical Outcomes
OBJECTIVE The present study aimed to simultaneously evaluate the association between expression of three potential factors [post-acrosomal sheath WW domain-binding protein (PAWP), phospholipase Cζ (PLCζ), and truncated form of the kit receptor (TR-KIT)] as candidates of oocyte activation with fertilization rate and early embryonic development. MATERIALS AND METHODS In this experimental study,...

متن کاملA Preliminary Report on Early Embryonic Development Following Oocyte Vitrification and In Vitro Fertilization in Sheep
Interest in oocyte cryopreservation has recently increased with the growing importance of in vitro embryo production, nuclear transfer, and gene banking (Gordon, 1997; Andrus et al., 2000). A relatively recent approach to achieve rapid freezing without the use of expensive freezing devices is called vitrification. Vitrification is defined as the physical process by which a highly concentrated s...
