A single injection of an experimental gene therapy treatment may be all that is required to permanently stop a female cat from reproducing, according to a small, proof-of-concept study.
For the first time, researchers at Massachusetts General Hospital (MGH), a founding member of Mass General Brigham (MGB), and their collaborators have demonstrated that a single dose of anti-Müllerian hormone (AMH) gene therapy can induce long-term contraception in the domestic cat, potentially providing a safe and effective alternative to surgical spaying.
