heal.abstractOBJECTIVE: To evaluate the effects of electrical stimulation of rabbit oocytes before round spermatid nuclear injection procedure on oocyte activation and fertilization. DESIGN: The ratio of activated oocytes to the number of successfully injected oocytes and the proportion of offspring to the number of activated oocytes after round spermatid nuclear injections into oocytes stimulated via mechanical stimulation (group A) or a combination of electrical and mechanical stimulation (group B) was compared. INTERVENTIONS: Round spermatid nuclei were isolated from mature male rabbits and microinjected into the oocytes of groups A and B. Injected oocytes were cultured for 24 hours. The embryos developed from groups A and B were transferred to synchronized recipient does. RESULTS: Embryos that developed normally through implantation in groups A and B were carried successfully through complete gestation in the recipient does. The ratio of the activated oocytes to the number of successfully injected oocytes and the proportion of offspring to the number of activated oocytes were significantly higher in group B. CONCLUSION: Electrical stimulation of oocytes before ooplasmic spermatid nuclear injections and ET procedures has beneficial effects on oocytes activation, fertilization, and subsequent embryonic development.en
