Embryo Developmental Potential in a Novel 2-step IVM System

"CAPA medium keeps oocytes in meiotic arrest for 22-24 hours. IVM medium allows oocytes to resume meiosis.~CAPA medium: 10% human serum albumin (HSA) + 10nM estradiol (E2) + 25nM CNP + 5ng/ml Insulin + 1mIU/ml follicle stimulating hormone (FSH) IVM medium: 10% HSA + 10nM E2 + 5ng/ml Insulin + 101mIU/ml FSH + 100ng/ml AREG CNP: peptide naturally occurring in follicles to maintain meiotic arrest, E2: estrogen, enhances effects of CNP, Insulin: basic growth factor used in cell cultures and component of commercially available LAG medium of the standard IVM system, AREG: downstream effector of the LHCG receptor which helps meiotic resumption. HSA, FSH and hCG are CE labeled. CAPA IVM medium is currently not yet available as CE marked commercially available medium and needs to be prepared in house."
