NCT07570342
Comparison of Two Types of Calcium (Ca²⁺) Ionophore Treatments for Oocyte Activation in Cases of Suboptimal Fertilization Potential
This study aims to investigate the effectiveness and safety of assisted oocyte activation (AOA) using Ca²⁺ ionophores in cases of total fertilization failure (TFF) due to oocyte activation deficiency (OAD). The study will be conducted in two phases: Phase I will compare the fertilization rates of oocytes exposed to two types of Ca²⁺ ionophore treatments- Ionomycin solution and commercially available CultActive-against a control group without calcium ionophore treatment. Phase II will assess whether an additional injection of CaCl2, prior to exposure to the chosen ionophore from Phase I, further improves fertilization outcomes. The goal is to identify the optimal AOA protocol for improving fertilization rates and to evaluate the safety and efficacy of this approach in relation to ploidy, with a focus on ensuring normal pre-implantation embryo development.
