Well, you're certainly right about THAT, Casperz. In fact, those sites said nothing AT ALL about the effect of spironolactone on T levels. I'm baffled as to why you went to the trouble of posting those first three links in the first place.
Are your serious? Did you read the three links? All of them talked
about testosterone.
How about this from the first link:
[quote:1edoa3pv]interference with the production of testosterone or its conversion to the potent metabolite 5alpha-dihydrotestosterone (DHT) can be exercised by drugs like spironolactone (AldactoneR) 100-200 mg/day
[/quote:1edoa3pv]
I made it clear in a previous post that what I'm specifically talking about is your claim that relatively low doses of spironolactone can reduce T levels to normal female levels. While it's not out of the question that 100-200 mg/day _may_ lower T levels a little, I'm still waiting for legitimate medical evidence stating that it lowers it to
female levels (not to mention even lower doses like only ~50 mg/day).

Or this from the second link:
Besides providing estrogen, a hormone regimen should also reduce testosterone to normal female levels. This usually requires adding an anti-androgen.
In persons who have not had an orchiectomy, reducing testosterone levels is also a concern. Although the desired reduction in testosterone can theoretically be accomplished with estrogen alone, the dosage required is usually in excess of what is needed for feminization. Adding an anti-androgen allows lower dosages of estrogen to be used; this is usually highly desirable. Typical dosages of anti-androgens are as follows:
Oral anti-androgens:
spironolactone (e.g., Aldactone®), 100-300 mg daily in divided doses; OR
cyproterone acetate (e.g., Androcur®), 100-150 mg daily.
Sometimes 100 mg of spironolactone may be sufficient, but 200?300 mg is a more typical dose.
Again, let's focus on the effect of spironolactone ALONE, without using other drugs like estrogen along with it. BTW, I consider that second site to be generally unprofessional and unreliable, because of that glaring error they made about how reducing testosterone levels "usually requires an anti-androgen". They have it BACKWARDS, of course: the normal response of the male body to antiandrogens is to INCREASE testosterone production, not lower it, in response to "pure" antiandrogens. The fact that they would make such a gross error makes me question everything else they say.

Or this from the third which is clearly discussing ramping up spironolactone from 100mg to 200mg ONLY if testostorone is a problem.
# Month 2: Given continued health, add anti-androgens: 100mg/day spironolactone plus fractional tablet (0.05-0.5mg)/day finasteride.
# Month 5: If androgens are still a problem (continued scalp hair recession, frequent spontaneous erections, etc.), given continued health, increase antiandrogens to the following: 200mg/day spironolactone plus larger fractional tablet (0.1-1mg)/day finasteride.
Yes, and notice what it is they consider to be a "problem": scalp hair recession, spontaneous erections, etc. Once again, they're not talking specifically about reducing testosterone to female levels.

LOL! I don't believe that, at all. There was probably a major problem with the blood test. (BTW, faulty blood tests are by no means a rare event.) And what other drug(s) was he taking at the same time?
Bryan... that is not the ONLY post that said that, that
was just ONE post... I've seen many reports like that, are you
going to discount every single one of them as bad blood tests?
It's the only one I've seen which _may_ purport to back-up your claim, and I'm not even ENTIRELY sure about that one, because of the issue having to do with other drugs he may have been taking.
casperz said:
I have no doubt that the reason transsexuals take spironolactone is to reduce their testosterone and I have no doubt that transsexuals report small doses can affect and lower testosterone.
A clear reason that they take spironolactone is, as the previous paragraph clearly shows, TO PREVENT ANDROGENIC EFFECTS like scalp hair recession, erections, etc. spironolactone does that by functioning as an ANTIANDROGEN, not (necessarily) by reducing testosterone levels, as you claim.
casperz said:
But that belief is based on first hand reports I've read, not studies.
Even those anecdotes are flawed and inconclusive, for the reasons I've already explained.
casperz said:
Can I assume you take spironolactone Bryan?
Oral spironolactone? No I don't.
