A linear karyotypic association between PB-I, PB-II and blastomere using sequentially performed comparative genome hybridization with no association established between karyotype, morphologic, biochemical (sHLA-G expression) characteristics, blastocyst formation and subsequent pregnancy outcome.

Background: The importance of oocyte/embryo ploidy to achieve implantation and a subsequent pregnancy.

Aim: To correlate first and second polar bodies and day-3 blastomere ploidy, embryo morphology and biochemical (sHLA-G) characteristics with blastocyst development and in vitro pregnancy outcome.

Materials And Methods: All oocytes/zygotes and embryos were individually cultured to the blastocyst stage.
