A meta-analysis found that tribulus improved erectile function scores in men with erectile dysfunction, but did not significantly increase testosterone.
Aim of the study: Tribulus terrestris is a medicinal herb purported to enhance reproductive function, particularly in instances of erectile dysfunction (ED). This study aims to assess the effectiveness and safety of administering Tribulus terrestris to patients with ED.
Results: Additionally, on both the IIEF-5 [MD 3.23 (95%CI 1.89, 4.58), p < 0.00001] and IIEF-15 [MD 14.44 (95%CI 5.75, 23.14), p = 0.001], Tribulus terrestris outperformed placebo. However, the two groups were not significantly different in terms of total testosterone levels. We observed no difference in the incidence of adverse events between Tribulus terrestris and placebo. Tribulus terrestris supplementation may offer benefits in improving erectile function among patients with ED with a relatively good safety profile.

A review found improved erections in some studies, but most reported no significant changes in androgen profiles.
Aim of the study: Background: Tribulus terrestris L. Zygophyllaceae (TT) is a plant that has been claimed to increase testosterone levels and improve sexual function, particularly erectile dysfunction, with potential benefits for male sexual health.
Results: TT supplementation at doses of 400 to 750 mg/d for 1 to 3 months improved erectile dysfunction in 3 of the 5 studies that assessed this parameter. Eight out of ten studies did not report significant changes in androgen profile following TT supplementation, but the subjects in the neutral studies did not have low androgen levels at baseline. Therefore, only 2 studies showed significant intra-group increase in total testosterone levels, which had low clinical magnitude (60-70 ng/dL) and involved subjects with hypogonadism. Conclusions: TT supplementation has a low level of evidence regarding its effectiveness in improving erectile function in men with erectile dysfunction, and no robust evidence was found for increasing testosterone levels.

In a study of men with late-onset hypogonadism, testosterone levels and erectile function scores increased after 3 months of taking tribulus.
Aim of the study: Aging is associated with a series of morphological and functional modifications that leads to reduced physiological efficiency and atrophy of various organs and systems. Tribulus terrestris induces its effect in fertility and sexual functions through the steroidal saponins, particularly the dominant saponins protodioscin.
Results: Moreover, there were significant elevations in the means of both total testosterone together with the score of the validated Arabic index of erectile function (5-item version of the International Index of Erectile Function) (2.2, 10.7 (before), 2.7, 16.1 (after), p < 0.001, p < 0.001, respectively). Finally, the mean of the total prostate-specific antigen was elevated in this group (1.4 (before), 1.7 (before), p = 0.007, respectively). Interestingly, there were no worsening of the lower urinary tract symptoms in group A as there was no change in the mean score of the international prostate symptom score, which was used to assess these symptoms before and after treatment (mean 14.4 (before), 14.6 (after), p = 0.67, respectively).
