Fig 5. The validated model in centiles.

Normative ranges for the model of total testosterone from ages 3–88 years. In the average case (red line) total testosterone remains constant for age > 40. However, the variance in normative ranges increases for these ages, with 1^st to 99^th centile ranges of 4.7–29.2 nmol/L at age 35 years and 3.1–35.2 nmol/L at age 88 years.
