Yes, there is a real process of diminishing returns in operation.

It’s why you often see photos of guys who used to be studs being waved about in the boney fingers of decrepit old men in wheel chairs reading comic books while you wonder to yourself…”was that really them, once upon a time?”

But why do testosterone levels fall?

Age related testosterone decline, or secondary hypogonadism has several main reasons for happening. I’m going to disgustingly simplify things a little by briefly mentioning two:

1. The mostly enzymatic conversion process that goes cholesterol->pregnenolone->testosterone becomes progressively more inefficient with time.

2. Leydig Cells, the little machines that run the above reaction, along with several others of major importance, become less sensitive to LH (luteinizing hormone) released by the pituitary as a sort of initiation signal to start the testosterone conversion process. The older man starts releasing more and more LH with less and less cellular responsiveness. Similar to the kind of occurrence happening in Adult Onset or Type 2 diabetes where a greater and greater amount of insulin is released in response to an increasing amount of tissue insensitivity.
Now, whether this happens at 30, 40 or 20, or 70, how and to what extent it happens, has as much to do with lifestyle choices, self image, mind-set and what you’re willing to stand for as it does with genetics and what havoc the human race is currently causing to the environment.

But all is not lost and life can still be fun and well worth living as Mother Nature, the bitch that she is, attempts to shut you down and convince you that she no longer has much use for you or your manhood as the clock winds down.

Stubborn You, of course, will undoubtedly have other ideas and probably not be quite so ready to throw in the towel just yet.

So, you use exercise discipline, use nutritional strategies, practice the warrior mindset, and investigate what modern medical science may be able to offer you.
