Tribulus terrestris is a herb grown in Africa, India, and parts of Eastern Europe, that has been used for its ability to boost the production of testosterone. Various reports are given concerning the degree of testosterone elevation, ranging from 30 to 50%. In younger men, where the testosterone level is already normally high, it is unlikely that the percent increase of testosterone would be as great as it would be seen in older men. Nevertheless, Tribulus terrestris is attributed with demonstrable value in athletic development, if augmented legal anabolic effects are valued. Its emerging use in North America has focused on athletic muscular and performance enhancement, and the medical sexual problems of erection dysfunction and reduced sex drive.

Testosterone is a natural endogenous anabolic steroid, unlike the synthetic or illegal anabolic steroids that are associated with adverse side effects. “Anabolic” is from the Greek words ana, meaning “upward”, and ballein, “to throw.” Athletic use of Tribulus terrestris results in greater muscle mass and stamina, and facilitates muscle recovery. Tribulus terrestris has been used for over 20 years by Eastern European bodybuilders and other athletes as an herbal approach to enhance muscle mass and performance.

The medical problems of impotence and failing sexual interest can stem from diminished testosterone production; while reduced testosterone levels may be thought of as an older man’s problem, the condition can develop without regard to age. Clinical understanding into the nature of erectile dysfunction encompasses a combination of factors; two central considerations are blood circulation of the penis and testosterone levels. Subtle downward changes in testosterone levels can combine with microcirculation factors to produce degrees of erectile dysfunction. Declining sexual interest could exist apart from erectile dysfunction and may respond to enhanced testosterone levels.

Your physician should determine your testosterone level. If found to be below the normal range for your age, an herbal stimulation of your own testosterone as a first step may be preferable to pharmaceutical drugs, including synthetic testosterone known as methyltestosterone.
