<unk>  is the measure of the ability of an oocyte (the female gamete) to achieve successful fertilisation. The quality is determined by the maturity of the oocyte and the cells that it comprises, which are susceptible to various factors which impact quality and thus reproductive success. This is of significance as an embryo's development is more heavily reliant on the oocyte in comparison to the sperm.
