Rating (out of 5): 2

Tribulus terrestris has been traditionally used in various systems of medicine, including Ayurveda and Traditional Chinese Medicine, primarily to support male reproductive health and enhance libido. Historically, it has been touted as an aphrodisiac and a remedy for sexual dysfunction and infertility. Traditional texts and anecdotal reports suggest it may improve sexual desire and performance.

However, scientific evidence supporting these claims is limited and mixed. Some small clinical studies have examined Tribulus’s effects on testosterone levels, libido, and sperm quality, with inconsistent results. A 2014 systematic review concluded that there is insufficient evidence to support Tribulus terrestris for improving sexual function or infertility in men, though a few trials found modest benefits in specific populations. The proposed mechanisms include saponins (notably protodioscin) that might influence androgen receptors or nitric oxide pathways, but robust human data are lacking.

In summary, while Tribulus terrestris is traditionally used for reproductive support, especially for male sexual health, scientific validation is limited and does not strongly support its efficacy for these purposes. Most claims are rooted in historical and cultural practices rather than conclusive clinical research.
