But this might be the problem, so the first step is to measure the testosterone levels in the blood. Morley notes the U.S. FDA estimates that there are 4-5 million U.S. men with low testosterone levels, a dangerous medical condition known as hypogonadism. Even so, both Morley and Bortz warn people to get reliable tests of their testosterone level before attempting testosterone therapy. There is a large number of studies that show libido will improve in older men when you improve testosterone levels. The reason to give testosterone to older men is not limited to sexual activity.
Sex is nice, but living is even more fun.
We have shown that the single best predictor of poor memory in middle-aged men is low testosterone. And when men are given it back, their memory improves. Morley has developed a questionnaire that can screen men for possible testosterone deficiency. Bortz agrees that testosterone has been used indiscriminately. This has several components, and the main one is hydraulics.
