Question:
Is it normal for a 14-year-old male, who started puberty at 12, to have adult levels of testosterone? My results were about 784.63 ng/DL, which I thought were quite high for someone my age considering the fact that I have a faint mustache and small amounts of body hair.
Answer
Here is a chart of typical testosterone levels in boys:
| 0 to 5 months | 75-400 ng/dl |
| 6 months to 9 years | Less than 7-20 ng/dl |
| 10 to 11 years | Less than 7-130 ng/dl |
| 12 to 13 years | Less than 7-800 ng/dl |
| 14 years | Less than 7-1,200 ng/dl |
| 15 to 16 years | 100-1,200 ng/dl |
| 17 to 18 years | 300-1,200 ng/dl |
| 19 years and older | 240-950 ng/dl |
The broad ranges are because boys enter puberty at different ages. But what I want you to notice is that during adolescence your testosterone levels are often higher than your adult levels.
