Plain-English summary
A Thoroughbred mare was brought in because she was displaying stallion-like behavior. After thorough testing, including hormone checks and imaging, the vet diagnosed her with androgen insensitivity syndrome, a condition where the body doesn't respond to male hormones. The vet performed surgery to remove her abdominal testicles, which successfully resolved her unusual behavior.

Abstract
A Thoroughbred mare was presented for stallion-like behavior. Reproductive and ultrasonographic evaluation, testosterone assays, and karyotyping confirmed a diagnosis of androgen insensitivity syndrome (64, XY--testicular feminization). Surgery to remove abdominal testicles was successful in alleviating the behavioral abnormality. This condition is discussed with reference to the current literature.
