[Cytogenetic analysis of unfertilized human oocytes].

The results of morpho-functional and cytogenetic analyses of 341 oocytes unfertilized in the course of extracorporal fertilization programme are presented. The causes of the "failure" during in vitro fertilization of the oocytes are discussed. Relation of the frequency of oocyte chromosome abnormalities (40.2%) on the patient age and cell maturity has been shown.
