Vulvar Wattle in a Jersey Calf.
A vulvar wattle is an epithelial structure that resembles a small bull penis and is suspended from the dorsolateral wall of the vestibule in an occasional heifer. No other anomalies are associated with it. Surgical removal is straightforward but does require a ligature at its base because it usually has an active central artery. Owners sometimes mistakenly think that their animal is a hermaphrodite. The dorsal location readily distinguishes it from the clitoris which is present in its normal location in the ventral commissure of the vulva.
