A transvaginal ultrasound probe speculum is designed for use with a generally cylindrical elongated ultrasound probe. The speculum has an elongated blade having a proximal end and a distal end, and a connector, such as a collar. The speculum has a lever that cooperates with the collar and the elongated blade for pivoting the blade relative to the ultrasound probe so that the blade and the ultrasound probe serve as the blades of the speculum.
