ABSTRACT
OBJECTIVE:
To explore the influence of polyspermy on IVF outcomes in in vitro fertilization and embryo transfer(IVF-ET).METHODS:
The data from 496 IVF-ET cycles and 5349 oocytes were analyzed retrospectively. A comparison of a number of fertility parameters with and without polyspermy was done. The fertility parameters were the number of oocytes retrieved, percentage of mature oocytes, fertilization rate, cleavage rate, occytes for ET, pregnancy rate.RESULTS:
The percentage of mature occytes, fertilization rate, cleavage rate was 67.0 %,76.7 %and 95.6 %, respectively( P< 0.01). The pregnancy rate was higher in polyspermic fertilization cycles (25.7 %) than in cycles without polyspermy(23.6 %),but with no statistical significance ( P>0.05).CONCLUSION:
Polyspermic fertilization is correlated with improved oocyte receptibility to sperm and could be considered as an encouraging sign for the success of IVF.
