the.com/virility

means The quality of being vigorously, robustly masculine — especially in physical strength and sexual potency.

from From Latin virilis, 'of a man,' rooted in vir, meaning 'man' (as opposed to woman or boy). That same vir gives English virtue — which originally meant manly excellence, courage, and strength before it softened into moral goodness. Virility kept closer to the original muscle of the word.
