Abstract

The aim of this study was to determine the effect of thiol compound, beta mercaptoethanol (β- ME) on the in vitro maturation (IVM) of oocytes. Good quality of cumulus oocyte complexes   were matured  in two groups of maturation media viz. TCM 199 + 10% FBS + PMSG (20 IU/ml) + hCG(10 IU/ml) + Sodium pyruvate (0.80 mM) + L-glutamine (2 mM) + Gentamicin sulphate (50 µg/ml) without b-ME (Group 1) and  supplemented with 100 µM b-ME (Group 2)  for 24 h in CO2 incubator. The present result revealed that a significant improvement in cumulus expansion and nuclear maturation was observed when buffalo oocytes were matured in maturation medium with b-ME. In conclusion, supplimentation of   b-ME in culture medium had a beneficial effect on in vitro maturation of buffalo oocytes.
