Size-specific follicle selection improves mouse oocyte reproductive outcomes

Size-specific follicle selection improves mouse oocyte reproductive outcomes.

Encapsulated in vitro follicle growth (eIVFG) has great potential to provide an additional fertility preservation option for young women and girls with cancer or other reproductive health threatening diseases. Currently, follicles are cultured for a defined period of time and analyzed as a cohort. However, follicle growth is not synchronous, and culturing follicles for insufficient or excessive...

Size Of Follicle and Oocyte Maturation Status in an Assisted Reproductive Technology Programme

Method : It was a prospective study done from September 2011 to May 2012 in the Department of Reproductive Medicine at a tertiary care hospital. Sixty patients undergoing assisted reproductive cycles either with agonist or antagonist protocol were included in this study. Follicles were subdivided into four arbitary groups according to their mean two dimension size, >21 mm, 16-20 mm, 12-15 mm an...

CPEB controls oocyte growth and follicle development in the mouse.

CPEB is a sequence-specific RNA-binding protein that regulates polyadenylation-induced translation. In Cpeb knockout mice, meiotic progression is disrupted at pachytene due to inhibited translation of synaptonemal complex protein mRNAs. To assess the function of CPEB after pachytene, we used the zona pellucida 3 (Zp3) promoter to generate transgenic mice expressing siRNA that induce the destruc...

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

Background: The fibroblast growth factors (FGF-4) are a group of heparin-binding single chain polypeptides that play a pivotal role in development, cell growth, tissue repairing and transformation. The aim of this study is to improve development and maturation outcome of vitrified mouse pre-antral follicle by adding of fibroblast growth factor (FGF) into medium culture. Materials and Methods: P...
