Re: testosterone Al Pater's message on study

[Guest guest]

Will:

1. Extreme CR (not recommended from this group) causes a reduction in

testosterone levels.

2. As we age our sex hormones decrease (as Tony said once: it's all

downhill after 18 yo)

3. HR is not a good idea. It has been found to be detrimental in woman NOT

beneficial. It took many years before the medical establishment reversed

its' stand on this - deciding that cancer was a possible " side effect " .

correction on #2: downhill after age 18 for men and testosterone that is.

Hi All,

In addition to what Francesca said, it seems that CR makes your testosterone

level

decrease at younger ages, whereas testes size and functional potential are

retained

into later life. Ad lib, testosterone levels rapidly decrease to levels

relatively

less than those of old CRers.
