ABSTRACT
<p><b>OBJECTIVE</b>To discuss the applied value of rescue intracytoplasmic sperm injection(ICSI) after complete fertilization failure during in vitro fertilization (IVF) cycles.</p><p><b>METHODS</b>After 16-18 h co-culture with sperm, all the unfertilized oocytes with the first polar body were re-fertilized by ICSI.</p><p><b>RESULTS</b>After rescue ICSI, the abnormal fertilization rate was 17.9% and the normal fertilization rate was 42.7%. Twenty-four hours later, the normal cleavage rate of the normal fertilized oocytes was 79.6%. On the day of embryo transfer, the good-quality rate of embryos was 29.7% (22/74). A mean number of 3.4 (54/16) embryos were transferred to the patient during each cycle. Clinical pregnancy was found in 3 cases out of the 16 (18.8%).</p><p><b>CONCLUSION</b>The applied value of rescue ICSI may be correlated with the number and maturity of oocytes on the retrieval day.</p>
