===Genitals (male)===
[[File:Male genitalia five Tanner stages.png|350px|thumb|Photos of the Tanner scale for males.]]
; Tanner I
: [[Testicle|testicular]] volume less than 1.5 [[liter|ml]]; small [[Human penis|penis]] ([[Puberty|prepubertal]]) 
; Tanner II
: testicular volume between 1.6 and 6 ml; skin on scrotum thins, reddens and enlarges; penis length unchanged 
; Tanner III
: testicular volume between 6 and 12 ml; scrotum enlarges further; penis begins to lengthen
; Tanner IV
: testicular volume between 12 and 20 ml; scrotum enlarges further and darkens; penis further increases in length and starts to increase in breadth
; Tanner V
: testicular volume greater than or equal to 20 ml; adult scrotum and penis

===Breasts (female)===
[[File:Female breasts five Tanner stages.jpg|240px|thumb|Photos of the Tanner scale for females]]
; Tanner  I
: no glandular tissue: [[areola]] follows the skin contours of the chest ([[Puberty|prepubertal]])
; Tanner II
: [[Thelarche|breast bud]] forms, with small area of surrounding glandular tissue; areola begins to widen 
; 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
; Tanner IV
: increased breast sizing and elevation; areola and [[nipple|papilla]] form a secondary mound projecting from the contour of the surrounding breast
; Tanner V
: breast reaches final adult size; areola returns to contour of the surrounding breast, with a projecting central papilla

===Pubic hair (both male and female)===
; Tanner I
: no pubic hair at all ([[Puberty|prepubertal]])
; Tanner II
: small amount of long, downy hair with slight pigmentation at the base of the [[human penis|penis]] and [[scrotum]] (males) or on the [[labia majora]] (females) 
; Tanner III
: hair becomes more coarse and curly, and begins to extend laterally
; Tanner IV
: adult-like hair quality, extending across [[mons pubis|pubis]] but sparing medial thighs
; Tanner V
: hair extends to medial surface of the thighs
