"Vet mentioned that it will bring down the aggression level as well it might not be as hyper. "
My male is not neutered ( six years old and very healthy - in fact vet does not want to neuter him).
Hate to advocate not neutering for others. There are negatives, but mainly, control your male so that unwanted litters never occur.
Nothing is as simple as it seems or as complicated as we make it~
Attitude is everything -- Pick a good one!
