Medical Why does the penis stop responding to testosterone after puberty?

AI Thread Summary
Penis enlargement procedures and surgeries currently lack effectiveness, raising questions about the absence of hormonal treatments for increasing penis size in adults post-puberty. The discussion highlights that receptors in penile tissue diminish their responsiveness to testosterone after puberty, which complicates the possibility of simulating a hormonal environment similar to that of puberty in adults. Despite advancements in medical technology, the inability to achieve measurable penis growth through hormonal means remains puzzling, especially given the high demand for such solutions. The thread is monitored for spam due to its sensitive nature.

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.

The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
