Castration extends life span in mice

Commenters focused on whether castration’s reported lifespan effect in mice might have parallels in other animals and humans. One asked why researchers do not use longevity records from veterinarians, since many pets are neutered. Another pointed to studies of castrated men and asked whether living longer would justify the procedure, while noting the irony of the familiar “in mice” caveat. Others wondered what testosterone does beyond supporting sperm production, and one suggested that its role in promoting growth could have costs later in life, including possible effects on prostate enlargement.

Views on the result ranged from curiosity to skepticism: one commenter called the research flawed and said it should be ignored, while another offered an evolutionary-style explanation, suggesting that resources not spent on reproduction might go toward self-repair. The discussion also leaned heavily on humor, including jokes about the World Economic Forum, padded cages, and “Castrati” as a model name. A pair of commenters extended that joke into mock AI product tiers called “Eunuch” and “Incel,” with the latter supposedly trained on dark-web data and prone to breaking containment. These quips framed the unsettling implications of the research without resolving whether its findings would matter for human longevity.
