The mean age of the oocytes donors was 36.8 years. Chromosome karyotype was obtained in 30 of unfertilized oocytes: 16 oocytes (53.3%) had a normal haploid chromosome complement; 5 (16.7%) were hypohaploid; 3 (10.0%) were hyperhaploid; 3 (10.0%) were diploid, 3 (10.0%) were polyploid. It may explain for early pregnancy loss, low pregnancy rate after in vitro fertilization.Mahidol UniversityMedicineArticleSCOPUS
