Involvement of anticentromere antibody in interference with oocyte meiosis and embryo cleavage

The aim of this study was to investigate the clinical significance of anticentromere antibody (ACA) among types of antinuclear antibody (ANA) in the properties of oocytes retrieved from infertile women. The rate of metaphase II oocytes or embryo cleavage was significantly decreased in patients with positive ACA compared with patients with negative ACA, suggesting that ACA is an essential marker for flawed oocytes in infertile women with any type of ANA.
