The Sexual Health Benefits of Tribulus Terrestris

Tribulus terrestris is a popular herbal supplement that is used to increase testosterone levels, sex drive, and DHEA. The plant that the supplement is extracted from is more commonly known as puncturevine, and it is native to southern Asia, southern Europe, and Africa. In this article I will discuss some research that explains to how Tribulus functions in the human body.

The active chemical components of Tribulus terrestris are steroidal saponins. The most active steroidal saponin in Tribulus called protodioscin. Protodioscin has been shown to trigger the release of nitric oxide in the erectile tissue in the penis. Nitric oxide signals the blood vessels in the penis to dilate (vasodilation), increasing blood flow, and leading to fuller, firmer erections. In animal studies, protodioscin was found to significantly increase testosterone and DHEA levels as well.

DHEA (dehydroepiandrosterone) is a steroid hormone that is secreted from the adrenal glands. It is the most abundant steroid in the body. In a research study conducted at Airlangga University, Tribulus was found to significantly raise DHEA levels in the adult males (+55% in diabetics, and +85% in non-diabetics). As a result, sex drive was increased in 60% of the men suffering from erectile difficulties (DHEA levels increased in men who were not suffering from erectile dysfunction, although by a lesser amount).

In animal studies Tribulus terrestris has demonstrated its ability to increase testosterone levels by as much as 50%. This was achieved by the mechanism of the protodioscin, which increases the luteinizing hormone (LH); the hormone that signals the body to produce testosterone. There is ongoing debate in the scientific community as to whether or not Tribulus can increase human testosterone levels above the normal range, but it is generally agreed upon that it can help restore and balance normal testosterone levels in men who suffer from suboptimal levels.

Overall, Tribulus can provide many health benefits. It has been shown to increase DHEA and testosterone levels, and release nitric oxide in erectile tissue. While the debate regarding its effects on testosterone levels continues, thousands of men all across the world attest to the power of Tribulus. You can read their testimonials all over the Internet, but you shouldn't take their word for it; you should consider trying out Tribulus yourself to see if it works for you. But, consult with your physician before starting any supplement regimen.
