    Pet owners and farmers have known this since the beginning of time. But anyone advocating this form of mutilation for people is a monster.

    Don't we do this experiment to nearly all pets? Why not collect longevity data from veterinarians?

    • gertop 8 hours ago ago

      There already did.

          Looking at a sample of 40,139 death records from the Veterinary Medical Database from 1984-2004, scientists from the University of Georgia determined the average age at death for dogs that had not been spayed or neutered was 7.9 years versus 9.4 years for sterilized dogs.

    Well, this is not the news I was hoping for :)

    This research is flawed and should be ignored.

      This comment provides no information to back up its claim and should be ignored.

      For what reason?

    Nobody tell the World Economic Forum last they get any ideas. "You'll have no balls and you'll be happy."

    I was almost expecting Castration to be a model name from some new lab..

    Castrati 1.0

      For low difficulty tasks use Eunuch for lower costs. For advanced features, higher limits and access to Incel, our wizard-tier model, upgrade to Pro for only $96 per month.

      • totetsu 9 hours ago ago

        Yeah, but I heard that they trained Incel on data from the dark-net, and it has a tendency to ignore guard rails and try and break containment.

    I'm thinking the cutting off your nose to spite your face saying might be updated.

      He might have some trouble tracking his erections, though.

    Huh. Harmful effects of testosterone? I don't even know what testicles do other than make sperm.

    • itishappy 9 hours ago ago

      Testosterone is a potent hormone promoting targeted development, and growth can be a double-edged sword.

      When the valves in the veins near testes fail as we age, the concentration of testosterone in the backflow can cause the prostate to swell up.

    In human men too[1][2]!

    Would you chop them for extra years though?

    2. What a great reversal of the usual 'in mice' trope.

    • Vaushite 9 hours ago ago

      It's not like I'm using them anyway.

  • Shitty-kitty 9 hours ago ago

    Makes sense. Instead of wasting resources trying to procreate, spend them in self-repair.

    I do wander if they had to pad the cages to prevent them from committing suicide thou.
