although whether this one little roof could handle two testes cases is debateable. ; )))))))))))))))))
it might just be one nut too many....if ya know what I mean............rolleyes!
Looks like they might pay for it now.

Aieeeee! Macho es bueno!!

The age related or disease/inflammation/etc related decline in the production of sex hormones by the peripheral glands is caused by a combination of molecular damage to the macromolelcular machinery/signaling /synthesizing pathways both in the hypothalamus/hypophysal axis as well as in the peripheral glands itself.
If a man (without any replacement therapy) is located in the highest 25% (quartile) of testosterone levels, it means most likely that his body/organs overall have suffered less degenerative/inflammatory/oxidative damage compared with his overall age group. This will certainly translate in a lesser incidence of health problems, way beyond a lesser drop in testosterone.
Thus testosterone here is mainly a marker of general health, less that the cause of the better general health.
This does not mean, that there is no benefit to the overall vitality, organ performancne ( beyond sexual activitires!) due to the higher levels of this vitral steroid hormone. But the degree of this contribution is not easy to gauge. There are many pos and some neg effects to high testosterone.
If Testosterone itself would be the major cause of the correlated good health as observed, then Testosterone replacement therapy would indeed serve to provide similar benefits as this corrrelative study , investigating "naturally high testosterone levels, showsl
But the studies on the use of testosterone replacement therapy in men deficient for it do not show a clear benefit pattern, - some benefits are regularly observed, of course- but the critically important benefit on the cardiovascular status is not clear from a review of the studies performed to date.
This is in contrast to the clear correlation of spontaneously higher levels of testosterone with health parameters as this study demonstratges. I repeat - correlation - only partly cause, for the reasons stressed above.
The feedback inhibition of externally applied/internally produced testosterone on the production of LH and FSH ( the "gonadotrope hormones" of the hypothalmus/hypophysis)
will lead to a lack of such gonadotropins ( and hence peripheral testosterone production in response to those) for a while, once the external source is stopped.
But the finer understanding of the mechanisms of that feedback allows to circumvent this feedback inhibition to a good degree:
It is the production of estrogens from testosterone, by the aromatase enzyme, that is the operative basis for that feedback.
Therefore, inhibition of the transformation of the exogenous testosterone into estrogens by inhibition of aromatase is one way to counteract this effect.
Thre are several highly effective prescription "aromatase inhibitors" and also some natural substances ( some polyphenols) that also inhibit this conversion by aromatase, with a much lesser efficacy and these effects are not well researched in human studies, due to the lack of financial incentive for the performer.
One downside I've heard is that the body might stop making testosterone at the same levels once therapy is started. This then would result in having to stay on testosterone therapy for life. I haven't really been able to confirm this with too many independent sources, so would welcome your opinion.
In short, if someone like myself starts testosterone therapy and then decides to stop -because of either negative sfx or no noticeable benefit -- will I end up worse off than when I began.
Thanks.

But re your last post, are you then saying that they don't know if its OK to go on and off testosterone therapy? I would like to try the experiment, but not if it means that if I stop taking it I will be worse off than before.
It is also important to keep in mind, why these hypothalamic releasing hormones are produced and located in the brain. The brain determines/has an influence on the setpoint for the feedback regulation based on signals that it perceives to fit the need for the production of such hormones. Thus a beautiful woman, emanating strong pheromones will increase the perceived need, as will a sexually fulfilling intense relationship.
The often castigated "need "; for some men to have a "second youth relationship" is possibly a reflection of such a recharged hypothalamic setpoint, with health benefits perceived/received beyond the immediate, obvious pluses and in spite of the often detrimental sociological consequences of such behaviour. In these situations peripheral testosterone levels will rise naturally. Goethes Frau "von Stein" was probably one historically known example of such delicately achieved health benefit...
------------------------
Possibly, then I should re-think supplemental testosterone therapy as the stimulating mechanism. Perhaps instead, you could write me an rx, for one of those instead.

There is a bodywide increase in inflammatory signaling/inflammation, with numerous detrimental consequences,
firstly simply because there is an "inflammatory focus" namely the liver with all the foreign antigens and the resulting immune attack, that sends activating signals out to every other not directly involved bodywide component of the immune system.
Secondly there is the "Trillion a day virions" destruction and peripheral reticuloendothelial system processing of the resulting viral antigenic debris, that will carry and spread the inflammation bodywide.
Thirdly, there are numerous neutralization ineffective yet readily produced immune complexes floating around in the peripheral circulation, ready to be trapped anywhere in the capillary bed of peripheral organs , with the potential consequence of initiating a complement activation right on site - instigating yet another proinflammatory chain reaction.
Nevertheless, the metabolic syndrome itself can and often is the cause for multiple endocrine functioning deficits, without any HCV infection, mainly because of the proinflammatory stimulus that is generated/originates in the abdominal fat and the negative consequence of the insulin resistance that hampers the functioning of peripheral tissues in itself eg the production of sex hormones. Obese men have lower testosterone levels, there is no doubt about that, furthermore obesity tends to lessen the positive feedback to be had from sexually stimulating relationships as mentioned above.
In a particular case one could only guess as to the relative contribution of HCV disease and the metabolic syndrome/lifestyle disease to an observed low level of endocrine functioning.
In studies this low level aromatose inhibition in men with mildy hypogonadal levels has by itself, without external testosterone, raised the total and even more substantially the free testosterone levels by 50 to 100%.
Wasn't she the gal in Young Frankenstein?

. It is the chemical androst-4-ene-3,6,17-trione, best to be described as a steroid derivative of estrogens ( additional "oxo"group in position 6), with exceptionally high binding affinity/or even covalent attachment to the Aromatase.
They call it a "suicide inhibitor" because once bound, it will not release the enzyme. Not necessarily a bad thing.
It has been tested eg in a trial in 16 eugonadal ( normal testosterone secretion/function) males and was effective in raising free testosterone by 90% and DHT by 200%. Thus far no neg effects on serum safety markers (like LFTs, lipid parameters) were observed.
Nobody knows if this would be safe long term and certainly nobody knows if it would additionally harm an HCV affected liver. 300mg is a high dose.
The use of these to increase male testosterone prduction by partial inhibition of the estrogen dependent feedback cycle to the hypothalamus has been tested experimentally, it does work in that it indeed increases total and free testosterone levels with no external testosterone provided, but it has not been approved for this reason, nor has its safety been tested. The main side effect to be expected is a reduction in male estrogens as well. I was basically referring to the fact that some practitioners(doctors) of male HRT probably use it off label for this purpose already.
