@ Lennon,
I´m very very sure that it is reversible even with peyronnes. It also very good can be that your peyronnes will also go away. When the body respondes well to androgens again, it will heal.
I worked a long time in the urologie and saw a lot. I have seen a young guy, who was so crasy to hold his dick in a Vowerk vacuum cleaner, this has some blades inside and his dick look looked like a massaka. It took 3 surgerys to get it look normal again and he was later able to have sex and get it up with no problems again. So, when even this guy can get his dick working back again, we can it do to. Well, ok, when our bodys start to react normal to androgens everything will go normal again. I´m very sure in this. So Lennon dont give up dont loose hope! And even, when your dick grows back to normal and still got, peyronnes. This is treatable. It´s a real horror to look down and feel a numb rubber smal dick… I have still some moments, where my dick can look very normal. This shows me that its not damaged for ever. Keep that in mind.
