Question:
At what tanner stage is an average 16-year-old?
Answer:
It is difficult to answer your question because people develop at different times.
- Stage 3 can start as early as 10 or as late as 17.
- Stage 4 can start as early as 12 or as late as 18. The average age for starting stage 4 is 15. Regardless of when the stage starts, it lasts about two years.
- Stage 5 can start as early as 15 or as late as 20.
Therefore, a boy can be anywhere from stage 3 to stage 5. However, the average boy will most likely be in stage 4.
