Abstract

BACKGROUND Human female meiosis is particularly error prone, leading to the generation of aneuploidy, a problem which increases dramatically with advancing age. Despite being of great clinical importance, the genesis of oocyte aneuploidy remains poorly understood. Cumulus cells (CCs) surround oocytes in antral follicles and play a crucial role in regulating their maturation. During this investigation, we aimed to obtain an insight into the follicular environment of oocytes that become aneuploid and identify non-invasive markers of oocyte chromosome status and competence.
