If neutering or spaying an animal is necessary to prevent unwanted babies, why not just give them a hysterectomy or vasectomy instead? Do the remaining hormones still have other negative effects?
In: Biology
Removing testicles is easier/cheaper than a vasectomy, and has the added effect of making males less aggressive and territorial. Steers and geldings are easier to handle than bulls and stallions, neutered dogs and cats get in fewer fights and have less urge to roam.
As far as females go, removing the ovaries is said to have some reduction in risk of cancer (can’t get ovarian cancer if you don’t have ovaries), but I’ve never noticed any positive behavior changes. I’ve only ever had female cats altered, and I asked for just the hysterectomy.
