Low testosterone causes muscle to wither

Gents, I've been warning you for years now that the risks of low testosterone go far beyond a gun with no ammo -- and one new study after another is backing me up.

The latest: Researchers have confirmed that seniors missing out on this critical hormone lose their muscle even faster than they lose their sex drive.

The study of 1,200 seniors found that men with the lowest levels had stick-figure arms and legs that were practically useless and no strength left in their grip.

Wave goodbye to that firm handshake... assuming you can still raise your arm.

These seniors even had trouble with the simplest of all activities, like standing up from a chair. I can't think of anything feebler than that, but believe it or not this gets even worse: Men with missing muscle mass are more likely to suffer from potentially crippling falls.

Now, I'm not saying you need bulging muscles like Popeye, especially in your senior years. But if you're starting to look more like Olive Oyl, you stand to lose a lot more than your manly strength -- because new research confirms yet another of my long-held beliefs: Testosterone is critical to cardiovascular health.

As I told you last month, men who suffer from low testosterone are a third more likely to suffer a heart attack and up to 50 percent more likely to experience a stroke.

Don't assume you're safe if you haven't had problems with your heart, muscles or erections yet -- because the loss of testosterone is so gradual most men don't even notice it.

Not at first anyway.

Then, one day, nothing seems to work right anymore -- and your butt is glued to your chair.

Don't wait for that to happen. Use whatever strength you have left to get out of that chair and off to the doctor, even if you need someone to carry you there.

Have him check your testosterone levels and top you off, and watch those muscles start to come back -- along with your energy, vitality and a little something-something "down there."

Younger men, you're up next. Keep reading for the latest threat to your manhood.
