A single born Ayrshire cow, aged 2.5 years and showing signs of virilism, was found to have abdominal testes with epididymides, some undeveloped Mullerian duct derivatives, a normal vagina, raised plasma testosterone levels and a 60XY genotype in all tissues examined. The animal was diagnosed as a case of testicular feminization. The differential diagnoses of XY gonadal dysgenesis and freemartinism are discussed.
