Interventions
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 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).
