Cumulus Cell Mitochondrial Activity as a Non-invasive Marker of Embryo Quality (FLIM)

Cumulus samples (CCs) will be collected following the protocol on the day of oocyte pick up (OPU). CCs are frozen by the cryo-tech method, then stored in liquid nitrogen at -196oC. Information of CC samples and processed date/time is recorded. After all, samples are collected, they will be transferred to The Needleman Lab, Northwest Lab Building 359,52 Oxford Street Cambridge MA 02138 to measure mitochondria metabolism using FLIM.
