P-128: Fibroblast Growth Factor Improves Oocyte Maturation in Vitrified-Thawed Mouse Follicles

P-116: Maturation Genes Expression during In Vitro Culture of Vitrified Mouse Preantral Follicles

Background: Evaluation of maturation genes expression and their pattern during in vitro culture of vitrified preantral follicles is an essential and could promote either vitrification procedure or culture condition. Materials and Methods: Preantral follicles (with 100- 130 μm diameter) isolated mechanically from 12-14 days old NMRI mice ovaries and divided into vitrification and control groups....

Combined Effect of Retinoic Acid and Basic Fibroblast Growth Factor on Maturation of Mouse Oocyte and Subsequent Fertilization and Development

Objective Many autocrine and paracrine elements that are produced within follicular niche have been the focus of much in vitro maturation research. The present study was carried out to compare retinoic acid and basic fibroblast growth factor (bFGF) efficacy on IVM of mouse oocytes, and their further dual consumption to reach an optimal protocol. MaterialsAndMethods GV oocytes obtained from two-...

P-36: Addition of Zinc in The Vitrification Medium Improves In Vitro Maturation of Oocytes Derived from Vitrified-Warmed Follicles

Background Follicle cryopreservation has been proposed as an alternative fertility preservation option. Follicles can be cryopreserved in intact ovarian tissue pieces or after isolation of individual follicles from the fresh ovarian tissue using enzymatic or mechanical techniques. Researchers have used different cryoprotectants and various techniques to improve cryopreservation. It is plausible...

Melatonin Impact on In Vitro Development of Mouse Preantral Follicles and Oocyte Maturation

Introduction: Melatonin acts as an indirect antioxidant and is a powerful direct free radical scavenger and direct responses to melatonin in the gonads are detected. This study aims to investigate the influence of different doses of melatonin on preantral follicle development and oogenesis of in vitro cultured mouse ovarian follicles. Materials and Methods: Preantral follicles with diamet...

Effect of Fibroblast Co-culture on In Vitro Maturation and Fertilization of Mouse Preantral Follicles

P-107: Vitrification and In Vitro Culture of Mouse Preantral Follicles in Presence of Growth Factors

Background: Cryopreservation of oocytes is an effective technology in assisted reproductive technology. Although successful vitrification of gametes has been reported in several mammalian species, the survival is generally low. The aim of this study was to investigate the effects of fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) on preantral follicle development after vitrifi...
