Jesus?

Estrus - The period of maximum fertility of the female. According to one of my dictionaries, involves most mammals, except humans. By golly, I think I found a site where I'll actually learn something.
I researched long and hard (probably a bad choice of words) on the equivalent period (oops, did it again) in the human male and finally found it.
It's technical name is:
adulthood.
Or as Leanne would have it, oadulthood.
