Abstract

The value of oocyte reinsemination in human in vitro fertilization (IVF) was evaluated in this study. Two groups of 25 cycles each were studied. In group 1 cycles, insemination of mature/questionably mature oocytes (judged by cumulus and corona cell appearance) at 6.5 hours postcollection yielded a fertilization rate of 42.3%. This value was significantly lower than that obtained with reinsemination (70.8%). In group 2, questionably mature oocytes were treated as immature and inseminated 24 to 30 hours postcollection. The fertilization rate of mature eggs in group 2 was 68.2%, with a reinsemination success rate of 40%. Triploidy rates and cleavage rates of mature eggs, fertilized either at initial insemination or reinsemination and of fertilized immature eggs, were similar within group 1 and group 2 cycles. In group 1, two pregnancies resulted from transfer of embryos arising solely from successful reinsemination, with one infant delivered. These results indicate that reinsemination offers a useful adjunct for IVF in cases where fertilization failure occurs.
