Quigley scale

Rating scale for morphology of human genitalia

The Quigley scale is a descriptive, visual system of phenotypic grading that defines seven classes between "fully masculinized" and "fully feminized" genitalia. It was proposed by pediatric endocrinologist Charmian A. Quigley et al. in 1995. It is similar in function to the Prader scale and is used to describe genitalia in cases of androgen insensitivity syndrome, including complete androgen insensitivity syndrome, partial androgen insensitivity syndrome and mild androgen insensitivity syndrome.
