Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The injected oocytes will be then exposed to the previously mentioned activating agents for the purpose of inducing embryo development. The successfully fertilized oocytes will be further kept in culture for up to 5 days as per standard IVF/ICSI. Results in terms of fertilization and embryo cleavage will be assessed and monitored for the remainder of the culture period. Developing embryos selected according to standard criteria will be replaced to the patient or will be cryopreserved.
Because fertilization failure carries such a high emotional and financial toll on our patients, at the present time, the only method to generate an embryo for these cases is to perform assisted oocyte activation in conjunction with ICSI. The research intervention - assisted oocyte activation - is believed to help alleviate the failed fertilization by obtaining some zygotes for the patient. In these cases of complete failed fertilization, intracytoplasmic sperm injection (ICSI) will be performed as a routine clinical treatment even if they are not enrolled in the study. After several failures, their reproductive physician may recommend the use of donor spermatozoa instead of the male partner's.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
gamete treatment- oocytes and sperm
The spermatozoa will be prepared in the standard fashion and utilized for injection after exposure to a membrane permeabilizing agent. Patient specimen will be selected through a synthetic, sterile, single-use, culture-tested mesh. The specimen will then be placed in a 37°C environment. After 30 minutes, the selected portion is retrieved from the other side of the mesh. The injected oocytes will be then exposed to the previously mentioned activating agents for the purpose of inducing embryo development. The successfully fertilized oocytes will be further kept in culture for up to 5 days as per standard IVF/ICSI.

After 30 minutes, the selected portion is retrieved from the other side of the mesh. The spermatozoa will be prepared in the standard fashion and utilized for injection or intrauterine insemination after exposure to a membrane permeabilizing agent. Human recombinant PLC-zeta will also be used if the spermatozoa have been confirmed to be PLC-zeta deficient. The injected oocytes will then be exposed to activating agents for the purpose of inducing embryo development. The oocyte activating agent is calcium ionophore and for sperm membrane permeabilization to assist in sperm DNA decondensation is streptolysin O (SLO).
