Tanner Stages
Tanner Stage Genitals (male) Breasts (female) Pubic hair (male and female)
I
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)
II
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)
III
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)
IV
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)
V
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+)
