Does finasteride block dht or cause the body to produce less dht?

[Davey Jones]

No, this is a good theory.. I unfortunately dont even know much about hormones, but I did read that estrogen levels might go up a bit when taking finasteride because DHT has been lowered. Im not sure if this would cause side effects, but it might! Maybe some guys (2&#37 just cant handle high estrogen, or maybe their estrogen levels are already high and propecia pushes it up over the edge? I really dont know.. I havent seen any studies that can really explain even why propecia causes side effects.. It would be nice if we could get some input from some medical experts in here!

Yeah, it might be possible that if their estrogen levels were slightly elevated to begin with, they may suffer side effects if the levels were caused to raise higher, past a "break point." That, or if aromatase was elevated to begin with. Or it could simply have to do with ratios (testosterone:estrogen, aromatase:5alpha-reductase, etc.) rather than a particularly high level of anything. Any number of things could be happening, but I would have to guess it has something to do with aromatase/estrogen. I'm surprised they didn't check these things.

Where did you read that they suspected that estrogen levels may go up if DHT was lowered? That would seem to support this idea. I'd like to read that, if you remember where that came from.

I bet what with these new FDA rulings and the few people who suffer being so vocal about it, Merck will want to get this figured out. And hey, guys, let's go easy on people who are suffering. You gotta understand why they may be a little passionate about the subject, even if they number very few. I mean, shouldn't you want this talked about. Wouldn't you like it if they figured this out and 100% of people could be helped by finasteride instead of 98%?

And hey, if they figured it out, you'd get to quit hearing all this whining. There's a plus, right?
