Introduction: Several factors are involved in failed fertilization following intracytoplasmic sperm injection (ICSI), which could be related to sperm, oocyte factors and/or both. Failure in oocyte activation is considered as the most important factor in failed fertilization after ICSI. To overcome this shortcoming, artificial oocyte activation (AOA) after ICSI has been suggested. Commonly, ionomycin and strontium chloride are used as the most efficient agents for oocyte activation in the clinic. In this study, for the first time, the clinical results of ionomycin and strontium chloride were compared on sister oocytes of couples who previously have had fertilization failure after ICSI.
Methods: In this intervention study, 14 couples with male factor infertility and previous failed fertilization after ICSI were included in this study. Oocytes of their wives were divided into two groups. Half of the oocytes after ICSI were treated with ionomicin and other half were treated with strontium chloride. Then, fertilization rate, embryo quality and pregnancy status were compared through SPSS 18 software, Paired sample t-test and chi-square test.
Results: Percentage of fertilization rate was significantly higher in oocytes that were activated using strontium chloride compared to those that were activated with ionomycin (p<0.0001). Although, the pregnancy rate was insignificantly higher in strontium chloride group than ionomycin group (p=0.387), but the quality of embryo was similar between the two groups (p=0.924).
Conclusion: In infertile men with previous failed fertilization after ICSI, the use of strontium chloride can also be recommended for oocyte activation
