It is estimated that over 70% of all serious impotence cases are the result of diabetes, kidney diseases, multiple sclerosis, endocrine disorders, vascular diseases, and high blood pressure, as well as neurological diseases. Men with secondary impotence are typically able to engage in intercourse only 25% of the time.
It does not work immediately. Furthermore, studies have shown that lack of testosterone leads to a range of other sexual performance problems, including premature ejaculation and low sex drive. In all, these studies proved that Tribulus works very well in curing sexual dysfunctions and maximizing sexual performance when taken regularly.
Modern public health
So, before you invest in costly and potentially dangerous chemical drugs, you may want to consider natural treatments for impotence. The ring remains on the penis until intercourse is finished.
This device works quite well, although some men complain about the discomfort of the elastic ring in addition to the hassle of, well, pumping up. A note of caution: Although there are many Tribulus extracts available over the counter today, almost all of these have been found not to contain any significant amount of the active ingredient. Prescribed drugs used to treat high blood pressure, ulcers, depression, and prostate cancer, as well as medications to prevent baldness or aid in dieting, can have side effects that include impotence.
The practice of vaccination became prevalent in the 1800s, following the pioneering work of Edward Jenner in treating smallpox. James Lind's discovery of the causes of scurvy amongst sailors and its mitigation via the introduction of fruit on lengthy voyages was published in 1754
Public health - early roots
Public health has early roots in antiquity. From the beginnings of human civilization, it was recognized that polluted water and lack of proper waste disposal spread communicable diseases (theory of miasma).
The focus of a public health intervention is to prevent and manage diseases, injuries and other health conditions through surveillance of cases and the promotion of healthy behaviors, communities and environments. Many diseases are preventable through simple, non-medical methods. For example, research has shown that the simple act of hand washing with soap can prevent many contagious diseases. In other cases, treating a disease or controlling a pathogen can be vital to preventing its spread to others, such as during an outbreak of infectious disease, or contamination of food or water supplies. Public health communications programs, vaccination programs, and distribution of condoms are examples of common public health measures. Measures such as these have contributed greatly to the health of populations and increases in life expectancy.
