SRY negative XX male in a French bulldog

Abstract

A thirteen-month-old French bulldog was referred for evaluation of a protrusion in the pubic region. Physical examination, radiographs and histopathological testing of both gonads following a gonadectomy indicated that the dog was a male pseudohermaphrodite. The karyotype was 78, XX chromosome, and the canine SRY gene was negative. Therefore, the present case was diagnosed as a SRY negative XX male in a French bulldog.
