The remedy for Testosterone decline with age is simple. Go to the gym 3 to 4 times a week and do very intense heavy weight lifting. Eat a good diet with ample protein and take a Zinc and Magnesium supplement. The Zinc and Magnesium suppress the conversion of testosterone to estrogen and the weight training naturally spikes HGH and testosterone production. I'm 48 and my recently tested serum testosterone level ( a Dr. buddy at the gym likes to establish a baseline) is the equivalent of a 20 year old. My significant other thinks it's pretty cool too. (wink, wink, nudge, nudge).
Interesting, because one thing about the average American diet now, compared to a generation ago is that we now eat a lot less meat (less zinc and protein), and way more refined carbs.
Foods historically associated with virility (oysters) are generally high in zinc.
