Table 1. Fertilization outcomes of bovine oocytes in vitro matured in the presence or absence of 50 μM TMG.

Results were assessed 18 h post insemination. MPNf (male pronuclear formation rate), SPZ/OO (mean number of spermatozoa per penetrated oocyte), MPN (number of male pronucleus in each penetrated oocytes). The data are compiled from three replicates and are expressed as mean ± standard error of the mean (SEM). Different letters in the same column indicate significant differences (P<0.05).
