Table 2 Experiment 2: comparison of pregnancies and live births following transfer of a single blastocyst (SET) derived from cumulus oocyte complexes matured either in IVM/IVC or in IVM-sup/IVC maturation media. Different letters in each column indicate the significance difference.

From: One carbon metabolism supplementation in maturation medium but not embryo culture medium improves the yield of blastocysts from bovine oocytes
