Vitrification by Cryotop and the Maturation, Fertilization, and Developmental Rates of Mouse Oocytes

Vitrification by Cryotop and the Maturation, Fertilization, and Developmental Rates of Mouse Oocytes

BACKGROUND Oocyte cryopreservation is an important part of modern fertility treatment. The effect of vitrification on the fertilization and developmental rates of embryo is still a matter of debate. OBJECTIVES This study aimed to investigate the effect of vitrification on the success of mouse oocyte maturation, fertilization, and preimplantation development in vitro. MATERIALS AND METHODS I...

vitrification by cryotop and the maturation, fertilization, and developmental rates of mouse oocytes

conclusions the present study showed that vitrification using cryotop and freezing medium can damage oocytes by reducing the maturation and fertilization rates in both developmental stages. results vitrification caused a significant reduction in the maturation rate of oocytes. of those that matured, the fertilization rate of vitrified ivm-mii (44.1%) and ov-mii oocytes (50%) was not significant...

The Effect of Vitrification on Mouse Oocytes Apoptosis by Cryotop Method

Background: Oocyte cryopreservation is one of the most important topics in the field of assisted reproductive technology to preserve women fertility, but relationship between cryopreservation and apoptosis is still a matter of debate. The present study was aimed to investigate the effects of vitrification on apoptosis in mouse oocytes by Cryotop method. Method: A total of 200 germinal vesicle (...
