Comparison of Different Vitrification Procedures on Developmental Competence of Mouse Germinal Vesicle Oocytes in the Presence or Absence of Cumulus Cells

Background An evaluation of the developmental competence of vitrified mouse germinal vesicle (GV) oocytes with various equilibration and vitrification times; in the presence or absence of cumulus cells and by comparison between the cryotop method and straws was performed. MaterialsAndMethods Mouse GV oocytes were considered in cumulus-denuded oocytes (CDOs) and cumulus-oocyte complexes (COCs) g...

P-89: The Developmental Rates of Early Mouse Embryos Derived from In Vitro Fertilization of Mature Oocytes Obtained from Ovarian Stimulation Using A Combination of HMG and Estradiol Valerate

Background: In recent years, a combination of hormones and agents in assisted reproductive technology (ART) cycles as a means of stimulating the ovary and developing more follicles. With respect to the positive effects of Estradiol Valerate on reproductive tissues and the impact on native genes of the egg that transferred to the embryo after fertilization, it seems that this agent can also effe...

P-66: The Effect of Vitrification on Distribution of ?9, ?v, ?1, ?3 Integrins Mouse Oocytes at GV, IVM-MII and OV- MII Stages

P-29: Effects of Cumulus Cells on Survival, In vitro Maturation,Fertilization and Subsequent Developmental Capacity of Mouse Germinal Vesicle Stage Oocytes during Vitrification

Background: Cryopreservation of oocytes, which is an interesting procedure to conserve female gametes, is an essential part of reproductive biotechnology. The objective of the present study was to investigate the effects of cumulus cells on survival,in vitro maturation,fertilization and subsequent developmental capacity of mouse germinal vesicle stage oocytes during vitrification. Materials and...
