More and more, we are finding low T in our male patients. This does not appear to be only because we are checking levels more often. A large study showed that average T levels have fallen from 1987 to 2007. Among 1,532 randomly selected men at three time periods between those years, there was a slow, steady decline in T levels such that a 65 year old in 2007 had 15 percent lower T than a 65-year-old in 1987 -- even correcting for being over weight or smoking.
Curious.
