Fertilization Arrest

Brief summary
We aimed to investigate the efficiency of chemical oocyte activation using readymade Ca2+ ionophore on cases with previously cancelled cases due to fertilization arrest at pronuclear stage i.e: cleavage failure to find out if there is any improvement in embryonic developmental stages.
Detailed description
Many studies reported that Ca2+ ionophore has a positive effect on embryo development in cases with complete or partial fertilization failure. However, only one preliminary report suggested a beneficial effect of Ca2+ ionophore activation in four cases with fertilization arrest.
Interventions
Ca2+ ionophore is a chemical agent used to perform oocyte activation after ICSI. It showed effective treatment to get better fertilization, pregnancy, and healthy livebirth in cases with total or partial fertilization failure.
