Gotts,
There are a lot of contradictory findings in the mix regarding finasteride and BPH. Here is my prediction (mainly based on the same predictions of others):
In the future, BPH (i.e., Benign Prostatic Hyperplasia -- which is what I believe you likely have; you should Google it) will be considered (read: "will be proven") to be a function of elevated estrogen levels (i.e., the estrodiol version of it). What I am saying is that the current belief that DHT is the culprit regarding the development of BPH, is wrong. I believe that estrogen causes and/or promotes the development of BHT. Not DHT. There may be a "dance" between the two, but the lead moves are conducted by estrogen. Your enlarged prostate is due to increase estrogen levels -- and BTW, statins certainly do increase estrogen levels in men. So that's the theory.
Factoid: one beer will immediately send a female's estrogen levels through the roof, for a while. Men who regularly drink can keep their estrogen levels in the stratosphere as it is not cleared out by the liver's P450 system since this system is constantly dealing with detoxifying alcohol (and statins, while on them). These extra estogen molecules then take up receptors on cells meant for testosterone, which, via a negative feedback cycle, tell the hypothalamus that you have plenty of testosterone and therefore no more is made -- so you get kicked hard twice. Your total testosterone level is lowered and perhaps worse, your estrogen/testosterone level is increased. A statin damaged liver would magnify the issue. I may have run into that phenomenon.
I researched finasteride enough to come to the conclusion that I was not interested in taking it -- but I have taken it for a short period in the past, and I have some right here should I change my mind in the future. (My interest was mainly fighting hair loss, but my HRT doctor was interested in trying it on my prostate just in case.) You can Google the downside of finasteride, it ain't a pretty sight for some men. Apparently most men do OK with it. My theory would appear to be wrong in that this stuff must do some good it would seem, but just because something is prescribed and said to be good, does not always mean much to me. Think statins as an example.
It is strong stuff. I started getting some gynecomastia due to its increase of unconverted testosterone (to DHT) whereby the extra testosterone "created" was converted to estrogen by the enzyme aromatase. I fixed that situation pretty quick. I was watching for it.
Finasteride inhibits the 5-Alpha Reductase molecule.
Here is a good URL to check out:
*http://en.wikipedia.org/wiki/5-alpha_reductase
It has been updated A LOT since I was there last many months ago. It is probably better now. It is the end that is the most important for me. But note a potential problem area here. There are two types of 5-Alpha Reductase, Type 1 and Type 2. One is said (according to some sources) to only have activity in areas including the skin and the other in areas including the prostate -- but that the same version of it does not work on both. However, finasteride is said to be one distinct type of reductase, but it is prescribed (in differing doses) for both conditions. It seems that something is not kosher here, one way or the other. But maybe there is an answer that I am just not getting yet. OK, here is the end text that I mention was important:
"Propecia (and other products containing finasteride)
causes a rise in testosterone levels, because
testosterone that would normally be converted into
DHT remains testosterone. Continual high levels of
testosterone in the body could possibly have negative
side effects.
Artificially low levels of DHT in the body could cause
some unwanted conditions. DHT is an antagonist of
estrogen. Men’s bodies also produce the female
hormone estrogen in the adrenal glands, although
this is just one-tenth of the estrogen that premeno-
pausal women produce in their ovaries. By reducing
DHT with drugs, a man’s protection from the effects
of estrogen may also be reduced. This could result
in gynecomastia.
Even though both finasteride and dutasteride were
developed to combat benign prostatic hyperplasia by
reducing DHT in prostate tissue, some scientists
question the wisdom of using these 5-alpha reductase
inhibitors in younger men who have no problem with
their prostates. A research chemist, Patrick Arnold,
says “Evidence is mounting that the existence of a high
estrogen/androgen ratio – a condition common in older
men – is highly correlated with the development of
benign prostatic hyperplasia.â€Â
