Public health

If you use these recreational drugs, however, you have bigger health problems than just impotence. Secondary impotence, defined as the loss of erectile function after a period of normal function, is more common.

The focus

In all, these studies proved that Tribulus works very well in curing sexual dysfunctions and maximizing sexual performance when taken regularly. Some of the most popular herbs available on the market today are Tribulus, yohimbe, ginkgo biloba, and others. The current diagnostic and statistical manual of mental diseases (DSM-IV) has included a listing for impotence.

Modern public health

More drastically, inflatable or rigid penile implants may be fitted surgically. Several types of FDA approved vacuum therapy devices are available with a doctor's prescription.

Institutions

The same goes for alcohol and narcotics, like heroin and cocaine. As testosterone and other male sex hormone levels start to drop after reaching middle age, low testosterone level is often the culprit in most intermittent impotence problems, especially in older men. Penile erection is managed by two mechanisms: the reflex erection, which is achieved by directly touching the penile shaft, and the psychogenic erection, which is achieved by erotic or emotional stimuli.

Vaccination

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

History

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).

Objectives

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.[4] 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.
