ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship of the incidence of polynuclear zygotes with clinical pregnancy after short coincubation of gametes in in vitro fertilization (IVF).</p><p><b>METHODS</b>We retrospectively analyzed 3 862 cases of short gamete coincubation IVF, which were divided into six groups according to the percentage of polynuclear zygotes 0,1-10%, 11-20%, 21-30%, 31-50%, 41-50%, and > or = 51%. We compared the rates of clinical pregnancy, implantation and abortion among the six groups.</p><p><b>RESULTS</b>No statistically significant differences were found in the patients'age, dose of gonadotropin, peak E2, number of follicles at the hCG trigger, and number of oocytes retrieved among the six groups. The 1-10% group showed higher rates of pregnancy and implantation, while the > or = 51% group exhibited lower rates of pregnancy and implantation but a higher rate of abortion than the other groups, none with significant differences (P > 0.05).</p><p><b>CONCLUSION</b>The incidence of polynuclear zygotes after short coincubation of gametes in IVF cannot serve as a prognostic indicator of the outcome of clinical pregnancy.</p>
