>The puer covets independence and freedom, opposes boundaries and limits, and tends to find any restriction intolerable.

Isn't that the opposite of this?

The word "testosterone" is not mentioned on this page at all. Nor any other hormones.

But you've given me quite an interesting endocrinology research project here. Last I heard, the root cause of the drop remains unknown. (And it's still dropping.)
