Listening to Andy Garcia talk about his son's latest hobby, you get the
sense that a toy caboose is just as important to the actor, director, and
musician as the release of his latest feature film, Ocean's Thirteen,
which opened last month to fanfare, here and abroad.
"He plays a lot of trains," Garcia says of the 5-year-old aficionado, and
then adds with gravitas: "He's an avid collector."
Unlike some of his overtly ambitious, publicity-seeking peers, Garcia, 51,
is a private man who treasures...
Experts don't suggest that low testosterone causes these conditions. In fact, it might be the other way around. That is, men with medical problems or who are in poor general health might then develop low testosterone.
Research into the relationship between low testosterone and several other health conditions is ongoing.
Diabetes and Low Testosterone
A link between diabetes and low testosterone is well established. Men with diabetes are more likely to have low testosterone. And men with low testosterone are more likely to later develop diabetes. Testosterone helps the body's tissues take up more blood sugar in response to insulin. Men with low testosterone more often have insulin resistance: they need to produce more insulin to keep blood sugar normal.
As many as half of men with diabetes have low testosterone, when randomly tested. Scientists aren't sure whether diabetes causes low testosterone, or the other way around. More research is needed, but short-term studies show testosterone replacement may improve blood sugar levels and obesity in men with low testosterone.
Obesity and Low Testosterone
Obesity and low testosterone are tightly linked. Obese men are more likely to have low testosterone. Men with very low testosterone are also more likely to become obese.
Fat cells metabolize testosterone to estrogen, lowering testosterone levels. Also, obesity reduces levels of sex hormone binding globulin (SHBG), a protein that carries testosterone in the blood. Less SHBG means less testosterone.
