The term "neutered" is typically used for animals, not humans. For female animals, neutering refers to the surgical procedure where the ovaries and uterus are removed, making them unable to reproduce. For humans, the term used is "sterilization" for the removal of reproductive organs, but it's important to recognize that procedures like this are personal medical decisions and should be approached with sensitivity and understanding.
