Tanner Stages | |||
---|---|---|---|
Tanner Stage | Genitals (male) | Breasts (female) | Pubic hair (male and female) |
prepubertal (testicular volume < 1.5 ml small penis of 3 cm or less) (typically age 9 and younger) |
no glandular tissue: areola follows the skin contours of the chest (prepubertal) (typically age 10 and younger) | no pubic hair at all (prepuberta] state) (typically age 10 and younger) | |
testicular volume 1.6 to 6 ml skin on scrotum thins, reddens and enlarges; penis length unchanged (typically age 9–11) |
breast bud forms, with small area of surrounding glandular tissue; areola begins to widen (10–11.5) | small amount of long, downy hair with slight pigmentation at the base of the penis and scrotum (males) or on the labia majora (females) (10–11.5) | |
testicular volume 6 to 12 ml scrotum enlarges further; penis begins to lengthen to about 6 cm (11–12.5) |
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) | hair becomes more coarse and curly, and begins to extend laterally (11.5–13) | |
testicular volume 12 to 20 ml scrotum enlarges further and darkens; penis increases in length to 10 cm and circumference (12.5–14) |
increased breast size and elevation; areola and papilla form a secondary mound projecting from the contour of the surrounding breast (13–15) | adult–like hair quality, extending across pubis but sparing medial thighs (13–15) | |
testicular volume > 20 ml adult scrotum and penis of 15 cm in length (14+) |
breast reaches final adult size; areola returns to contour of the surrounding breast, with a projecting central papilla. (15+) | hair extends to medial surface of the thighs (15+) |
