Genitals (male) 166px|Illustration of the Tanner scale for males. Tanner I testicular volume less than 1.5 ml; small penis (prepubertal; typically age 11 and younger) Tanner II testicular volume between 1.6 and 6 ml; skin on scrotum thins, reddens and enlarges; penis length unchanged ( 11 – 12 ) Tanner III testicular volume between 6 and 12 ml; scrotum enlarges further; penis begins to lengthen ( 12 – 14 ) Tanner IV testicular volume between 12 and 20 ml; scrotum enlarges further and darkens; penis increases in length ( 14-15.5 ) Tanner V testicular volume greater than 20 ml; adult scrotum and penis ( 15.5 +) 350px|center|Photos of the Tanner scale for males. Breasts (female) 240px|Photos of the Tanner scale for females. 240px|Illustration of the Tanner scale for females. Tanner I no glandular tissue: areola follows the skin contours of the chest (prepubertal) (typically age 10 and younger) Tanner II breast bud forms, with small area of surrounding glandular tissue; areola begins to widen (10–11.5) Tanner III breast begins to become more elevated, and extends beyond the borders of the areola, which continues to widen but remains in contour with surrounding breast (11.5–13) Tanner IV increased breast sizing and elevation; areola and papilla form a secondary mound projecting from the contour of the surrounding breast (13–15) Tanner V breast reaches final adult size; areola returns to contour of the surrounding breast, with a projecting central papilla. (15+) Height Growth Conclusion Sometime during Tanner 5, females stop growing and reach their adult height, usually this happens in their mid teens at 15 or 16 years for females. Males also stop growing and reach their adult height sometime during Tanner 5, usually this happens in their late teens at 18-19 years for males. Criticism The scale has been criticized by the pornography industry for its potential to lead to false child pornography convictions, such as in the case when United States federal authorities used it to assert that pornographic actress Lupe Fuentes was underage. Fuentes personally appeared at the trial and provided documentation that showed that the DVDs in question were legally produced.
