First, to access the legend created by seaborn needs to be done via the seaborn call.

g = sns.factorplot(...)
legend = g._legend

This legend can then be manipulated,

legend.set_title("Sex")
for t, l in zip(legend.texts,("Male", "Female")):
    t.set_text(l)

The result is not totally pleasing because the strings in the legend are larger than previously, hence the legend would overlap the plot

One would hence also need to adjust the figure margins a bit,

g.fig.subplots_adjust(top=0.9,right=0.7)
