Do males change when they are neutered?

[GetShelly]

My boy Mo, is 5 1/2 months old and is going to be neutered at 6 months. Right now he has some bad habbits.

1. He sprays
2. He rumblestruts all the time
3. He whistles (talks) to the 2 females I have in separate cages.

Will any of this behavior be eliminated (or at least reduced) after the operation? I plan to put him in the same cage as the ladies after the surgery (and after the 3 week healing period is up).

Thoughts????

Maybe just the spraying will stop. The rumblestrutting will continue. If he´s with the sows, he won´t have to wheek at them, so that may subside.
