Tanner Stages | |||
---|---|---|---|
Tanner Stage | Genitals (male) | Breasts (female) | Pubic hair (male and female) |
prepubertal (testis volume < 1.5 ml small penis (3 cm or less) (age 9 and younger) |
no glandular tissue areola follows the skin contours of the chest (prepubertal) (age 10 and younger) |
no pubic hair at all (prepuberta] state) (age 10 and younger) | |
testis volume 1.6 to 6 ml skin on scrotum thins, reddens and enlarges penis length unchanged (age 9–11) |
breast bud forms, with small area of surrounding glandular tissue areola begins to widen (age 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) (age 10–11.5) | |
testis volume 6 to 12 ml scrotum enlarges further penis begins to lengthen to about 6 cm (age 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 (age 11.5–13) |
hair becomes more coarse and curly, and begins to extend laterally (age 11.5–13) | |
testis volume 12 to 20 ml scrotum enlarges further and darkens penis increases in length to 10 cm and circumference (age 12.5–14) |
increased breast size and elevation areola and papilla form a secondary mound projecting from the contour of the surrounding breast (age 13–15) |
adult–like hair quality, extending across pubis but sparing medial thighs (age 13–15) | |
testis volume > 20 ml adult scrotum and penis of 15 cm in length (age 14+) |
breast reaches final adult size areola returns to contour of the surrounding breast, with a projecting central papilla (age 15+) |
hair extends to medial surface of the thighs (age 15+) |
Note that while typical ages are shown in brackets, this is not a system for determining age.
