| The description of Tanner stages for breast development: |
| 1. Prepubertal |
| 2. Breast and papilla elevated as small mound; areolar diameter increased |
| 3. Breast and areola enlarged, no contour separation |
| 4. Areola and papilla form secondary mound |
| 5. Mature; nipple projects, areola part of general breast contour |
| For penis and testes: |
| 1. Prepubertal, testicular volume <4 mL |
| 2. Slight enlargement of penis; enlarged scrotum, pink, texture altered, testes 4–6 mL |
| 3. Penis longer, testes larger (8–12 mL) |
| 4. Penis and glans larger, including increase in breadth; testes larger (12–15 mL), scrotum dark |
| 5. Penis adult size; testicular volume > 15 ml |
