Poor genital health seems to have become a major and worsening epidemic around the world. European men produce 50 % less live semen than 30 years ago. The density drops 2-4 % a year. As much as 40 % of 40-year-old men and 50 % of 50-year old men suffer from occasional or chronic erectile dysfunctions.
We also know that men all over the world are producing significantly less testosterone now than decades ago. This vital masculine hormone, manufactured in the testicles, keeps up the muscle size and condition and memory in the long run, sexual capabilities, and the masculine characters like determination and firmness. Testosterone is also needed to maintain the memory in the middle and older age.
Prostate overgrowth (almost all have it at 60 years of age) and prostate cancer (every sixth man gets it) strike fear into the middle-aged men. Ailments are often kept secret because of their private and awkward nature.
Our modern way of life is clearly disastrous to the genital health. For millions of years the male genitalia enjoyed a free and cool environment without pressing and hot clothes, with a lot of movement, ventilation and free blood and lymph circulation without any pressure. Modern clothing trends, prolonged time spent sitting, the overall poor nutrition, and condition of the circulatory system all reduce healthy metabolism in genitals.
