dc.description.abstractIn assisted reproduction, the selection of gametes to achieve better clinical outcomes is a crucial task of embryologists. The quality of the oocyte is a key factor in female fertility, reflecting the intrinsic potential of gamete development, and has a vital role not only in conception but also in subsequent embryonic development. Oocyte dysmorphisms are classified into two types: cytoplasmic, including the presence of granules and/or cytoplasmic inclusions (vacuoles, refractive bodies, and aggregates of the endoplasmic reticulum), and extracytoplasmic (changes in the shape of the oocyte, the zona pellucida, the space perivitelline changes and the polar body). Variations in oocyte morphology may occur due to factors such as the age of women, genetic problems and changes in the hormonal environment to which the oocyte is exposed in ovarian hyperstimulation. The classification of oocyte morphology and its correlation with embryo development and pregnancy rates are controversial in the literature. Several studies show no association between oocyte dysmorphisms and the results of in vitro fertilization, while others report an association between oocyte morphology and embryo development. These differences in the results can be explained by the use of different morphological criteria due to a lack of standardization of oocyte evaluation. © Todos os direitos reservados a SBRA - Sociedade Brasileira de Reprodução Assistida.en
