Alternatives to traditional spay/neuter

Linda Brent, PhD

Executive Director, Parsemus Foundation

Pet owners are hearing more and more about the potential for negative health impacts of traditional spay and neuter. Since most pet sterilization surgeries remove the reproductive organs responsible for the production of sex hormones, a number of ailments may occur due to this hormonal imbalance. But a growing number of veterinarians offer alternatives. Parsemus Foundation maintains a wealth of information on the research in this area and on different options available to pet owners. To keep hormone levels at normal levels while controlling pet overpopulation, some owners may choose vasectomy for males or ovary-sparing spay for females. The resources page also includes a list of veterinarians who offer alternative procedures. If you are a vet who wants to be included, please contact us at
