A boy with hormones has reasons to act like an idiot, be distracted, be irritated or frustrated with other boys. This can make training more challenging. Some of us have no problems working with boys in classes, and starting them young and working through adolescence we really don't have major issues.
But if boy-hormones makes training a pain, then removing boy-hormones might make training easier. If training is easier, one might be less likely to skive off training as often. If training is fun, then one is more likely to train more, or train more effectively, or train more meaningfully. And everything follows. More training, more mental exercise, better bond, better control of the dog.
End of story.
Short answer: neuter your young male, and make training fun.
