The only studies you can post that show that androgens "stimulate" body hair, is when the body hair samples have "ALREADY" been changed from vellous follicles in-vivo.
Even if that's true (and I'm not saying it IS true, I'm saying IF it's true), so what?? What does that have to do with anything? You've made a claim in plain English that I think is obviously and patently FALSE, and every single person on this forum knows it. I don't care WHY androgens directly stimulate the growth of body hair follicles, the only issue here is DO THEY or DON'T THEY. And it's laughable to everyone reading this thread that it's like pulling teeth just to get you to answer such a simple question!
[quote="S Foote.":5bfa4]Again Bryan, the in-vitro tests clearly show that androgens do "NOT" directly convert "ANY" follicle sample into a different growth rate!
Sorry, Stephen, but there's only ONE little observation in ONE little study which has gotten you so worked-up. It doesn't mean much.

The fact that androgens "then" support the pre-existing growth characteristics of follicles in-vitro, is meaningless to the question of how we get from one growth state to another!
Again, "MANY" substances could support the pre-existing growth characteristics of follicle cells in-vitro. Do we then claim these other substances "CAUSE" male pattern baldness? Of course not :roll:
But I'm not talking about male pattern baldness right now, I'm challenging a claim that you made in plain English. You claimed that androgens have no direct effect on hair follicles, and this statement can be tested in a very simple and direct fashion by giving androgens to hair follicles growing
in vitro, and seeing if the androgens have any effect on them (either positive or negative).
Because you know as well as I do that they sure as hell WILL have an effect on their growth, it is absolutely LAUGHABLE that you refuse to acknowledge what every other person on this board already knows. And your attempts to make excuses for that phenomenon by blaming it on something else are simply pathetic. The question isn't WHY androgens stimulate the growth of body hair follicles, the question is DO THEY or DO THEY NOT stimulate them. That's a simple YES or NO, buddy! :wink:

God Bryan, you are reaching your ranting phase ever earlier in these threads. :lol:
OK, if nothing else we Brits are a sporting breed, so i will go through this again so you can't keep on fudging the issue :roll:
You posted this:
"So getting back to what I said from the beginning: if I show you an in vitro study which found a stimulation of body hair growth from the addition of androgen, you'll recant your theory? I want you to state this CLEARLY right up front, so that you can't try to deny it later. "
You want me to recant my theory based on a factor that isn't even relevant to my theory! Thats very scientific Bryan (not)!
I have already accepted that androgens in-vitro "DO" apparently mirror the androgen induced growth characteristics in-vivo, but this is not the scientific point.
It is clear that androgens are "NOT" directly changing the pre-existing growth characteristics of the samples, this is the important point in terms of the current theory you try to "excuse".
Now if androgens "DID" directly stimulate pre-puberty vellous pubic follicle samples, into post puberty type pubic hair follicle cells, my theory would be in trouble! But again androgens "DO NOT" directly do this!
So just show me "ANYTHING" you have to the contrary that proves me wrong Bryan? Show me these studies you have that show androgens "CHANGE" the pre-existing growth characteristics of "ANY" follicle?
You can't, they don't, simple!
My theory explains this "changed" response to androgens (or any other substances) in-vitro. This occours by the normal cell growth potential changes induced in-vivo at the genetic level, by the growth rate allowed by contact inhibition within cells.
Scientificaly, your the one with the big problem here Bryan!
You have said many times on these boards that you believe that androgens directly "change" hair growth characteristics. But the in-vitro studies clearly prove this wrong.
Oh i know you will try to "invent" a biologicaly un-precedented excuse for this, but that isn't real science is it! :wink:
