abstract

background:   objective: the aim of this study was to evaluate the in vitro developmental competence of mouse vitrified pre-antral follicles in comparison to isolated pre-antral follicles derived from vitrified ovaries in the presence of alpha lipoic acid (ala).   materials and methods: pre-antral follicles derived from fresh, vitrified-warmed ovarian tissues and vitrified–warmed pre-antral follicles were cultured individually with or without ala, followed by adding hcg to induce ovulation. the follicle growth, oocyte maturation, and embryo development were assessed. results: the diameter and development of follicles, oocyte maturation and embryo development rates were significantly higher in ala supplemented groups compared to the respective ala-free conditions groups. aforementioned parameters were significantly higher in vitrified-warmed follicles in comparison to follicles derived from vitrified-warmed ovaries. conclusion: these findings support a superior performance of pre-antral follicles when vitrified rather than when isolated from vitrified ovaries with regard to increasing the rates of developmental parameters. moreover, ala improves the in vitro maturation of pre-antral follicles in vitrified and non-vitrified samples. cryopreservation of ovarian tissues and pre-antral follicles is a promising prospect for preservation of women fertility.

Total Oxidative status of Mouse Vitrified Pre-Antral Follicles with Pre-Treatment of Alpha Lipoic Acid

Background: Cryopreservation of pre-antral follicles is a hopeful technique to preserve female fertility. The aim of the present study was to evaluate reactive oxygen species (ROS) and total antioxidant capacity (TAC) levels of mouse vitrified pre-antral follicles in the presence of alpha lipoic acid (ALA). Methods: Isolated pre-antral follicles (140–150 µm in diameter) were divided into vitrif...

P-224: The Effect of Alpha Lipoic Acid on ROS Production and TAC Levels of Cultured Isolated Pre-antral Follicles Drived from Mice Vitrified Ovaries

Background: Ovarian cryopreservation is an efficient way to preserve fertility of cancer patients before chemotherapy. This study was designed to evaluate the effect of apha lipoic acid (ALA) on reactive oxygen species (ROS) production and total antioxidant capacity (TAC) of cultured isolated pre-antral follicles derived from vitrified and non-vitrified ovarian tissue. Materials and Methods: Im...

P-36: The Effect of Lipoic Acid on Developmental Competence of Cultured Isolated Mouse Preantral Follicles

Background: α-Lipoic acid (LA) is a cofactor in mitochondrial multienzyme complexes and is well-known for its antioxidant properties in both of in vivo and in vitro condition. Materials and Methods: Preantral follicles were isolated from 2 weeks old NMRI mice ovaries. LA at concentrations of 0 and 100 μM was supplemented to culture media (α-MEM medium supplemented with 5% FBS, 100 mlU/ml FSH, 1...
