Ultrastructure of immature and mature human oocytes after cryotop vitrification
In vitro maturation of vitrified immature germinal vesicle (GV) oocytes is a promising fertility preservation option. We analyzed the ultrastructure of human GV oocytes after Cryotop vitrification (GVv) and compared it with fresh GV (GVc), fresh mature metaphase II (MIIc) and Cryotop-vitrified mature (MIIv) oocytes. By phase contrast microscopy and light microscopy, the oolemmal and cytoplasmic...
متن کاملP-132: The Effect of Vitrification on Mouse Oocytes Survivale Rate and Apoptosis Using Cryotop
Background: Vitrification of oocyte is one of the most important topics in the field of assisted reproductive techniques (ART). Considering the importance of oocyte vitrification in clinics, in the present study the effect of vitrification on mouse oocytes survivale rate and apoptosis by cryotop were investigated. Materials and Methods: 200 GV oocytes and 200 MII oocytes were obtained respectiv...
متن کاملIn vitro survival rate of bovine oocytes following vitrification in glass capillary micropipette (GCM)
The purpose of this study was to evaluate the use of glass capillary micropipette (GCM) as a vessel forvitrification of bovine oocytes. Cumulus-oocyte complexes (COCs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (TCM-199 + 20% FBS) and randomly assigned to treatment andcontrol group. In the first step of vitrification, COCs were exposed to first vitrification...

High survival of mouse oocytes using an optimized vitrification protocol
The method of vitrification has been widely used for cryopreservation. However, the effectiveness of this method for mammalian oocytes could be improved by optimizing each step of the process. In the present study, we tested the effects of varying several key parameters to determine the most effective protocol for mouse oocyte vitrification. We found that cryoprotectant containing ethylene glyc...
