exactly, most of culture changes fast and for there to be a sexually selective pressure on testicles for a long enough time to make a difference, it would surely persist into recorded history. Either human mating practices are cultural and transitive so they would not exert continuous evolutionary pressure, or they are somehow more ingrained and thus could exist long enough to trigger noticeable evolutionary changes.
