(by the way, I have periodically noticed that if I have been off SP for awhile and resume it I will sometimes get an actual boost in "horniness" upon resuming SP...odd... maybe Lotus can explain that...tee hee).

Less testosterone being converted into DHT equals more free/total T in the bloodstream? DHT is responsible for a lot of undesirable male traits, like body/facial hair, body odor, and fat distribution, but I've never read that it has anything to do with sex drive. I think that has more to do with free/total T.

Sorry to crash the thread. My story is a lot like Sammie's btw, minus the need for trips to dress. ;p

Sarah is absolutely correct, Testosterone is responsible for sex drive, for Testosterone to promote youthful sexual interest it must be freely available to cell receptors. As we age T becomes bound to serum (blood) globulin. The component that renders free testosterone inactive is called sex hormone binding globulin (SHBG). This means your getting a double whammy of interference with sex drives in aging males,

1) Testosterone being bound to serum globulin (blood)
2) SHBG rendering it inactive

So that means estrogen takes it place!

Imagine if we knew more about Testosterone, we would find out that a reduction of free T also causes depression. Does anybody remember this statement?-High serum levels of estrogen also trick the brain into thinking that enough testosterone is being produced, further slowing the natural production of testosterone.

High estrogen can shut down the normal testicular production of testosterone. Aging men sometimes convert testosterone to estrogen. For testosterone to produce long-lasting libido enhancing effects, it must be kept in the "free" form in the bloodstream. It does not matter how much serum free testosterone is available if excess estrogen is competing for the same cellular receptor sites.


I wonder if I had been diagnosed years early for low T and they knew to test for free T would I be micro-managing my GD today?
