Testosterone is the main male hormone, which is responsible for the main male functions, hair growth, sexual activity, prostate functioning and many more. Most of the men start to think about such things like hormones when they become aged and they begin to see the first signs of low activity, usually connected with erection problems and low appetite for sex.
According to the information provided by endocrinologists all over the world, for the last decade this problem became more serious. But many doctors think that the problem of low testosterone in men has always existed, but in the old times men were more shy and confused to report about any sexual problems they may have. Nowadays people are freer, and more men are asking for medical help when they face the problem of bad erection or they don’t want to have sex any more.
