Disorder - Persistent Mullerian duct syndrome

Presenting Signs

Persistent Mullerian duct syndrome is a defect where the female genital tract, which is present in the early embryonic stage, fails to regress as the male embryo develops. Affected animals may present with normal external genital features (scrotum, testes and penis), or may have undescended testicles. Internally, the female genital tract (e.g. uterus, cervix and incomplete vagina) are also present. These animals are at increased risk of urinary tract infection and infection of the uterus. The disorder has been described in dogs.
