Why does the penis stop responding to testosterone after puberty?

[jaumzaum]

Penis enlargement procedures/surgeries are not that effective yet. I was wondering why there isn't any hormonal treatment that increases penis size in adults after puberty. Why the receptors in our penis tissue stop responding so well to testosterone after puberty? Biochemistrily speaking, why can't we simulate the puberty hormonal environment in an adult, even a little, and get a measurable penis growth? I find it very weird that with our current medical technology this is not yet possible, although there is a very high demand for it.
