Vulvar Wattle in a Holstein Calf.

Vulvar Wattle in a Holstein 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. It may protrude from the vulva. 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.
