Many oocytes fail to fertilize and cleave in vitro and many embryos transferred back to uterus fail to implant or maintain implantation. Chromosomal abnormalities in the male and female gametes may contribute to this loss. The higher incidence of meiotic chromosomal abnormalities bas been found in oocytes than in sperm. The wide range of incidence of chromosomal abnormalities in unfertilized oocytes has been reported in human IVF program (26-63%). However, factors affecting chromosomal abnormalities are not well understood. The present study has been conducted to investigate effects of the method for ovarian hyperstimulation, women's age, and the number of oocytes retrieved per patients on the incidence of numerical chromosomal abnormalities. Five hundred eighty four unfertilized metaphase II oocytes were subjected to chromosomal analysis. Included unfertilized oocytes were from 220 patients (mean
