Currently, the main task of reproduction is the rational use of human gametes and embryos. In ART programs can often observe the appearance of oocytes with various damages. These lesions oocytes can be divided into two groups: extracytoplasmic and intracytoplasmic. To extracytoplasmic pathologies include violation of the structure and shape of the zona pellucida, debris in perivitelline space and areas increase, the first polar body abnormalities (increase in size, degeneration, multifragmentation), and violation of the symmetry of oocyte oolemm. To intracytoplasmic anomalies oocyte cytoplasm include granularity, smooth endoplasmic reticulum aggregates, refractory bodies, vacuoles, violation viscosity of the cytoplasm. This article discusses criteria for evaluating oocyte quality in cryocycles and forecast the success of cryopreservation by vitrification, depending on the quality indicators cells.References
