While anecdotal reports suggest otherwise, several human and animal studies show that Tribulus terrestris does not cause a significant increase in testicle size or weight. This article delves into the research behind these findings, separates fact from fiction, and explains what you can realistically expect from a Tribulus supplement.

While animal studies have shown L-arginine supplementation can increase testicular weight and volume in species like boars and roosters, there is no clinical evidence to suggest that L-arginine increases testicle size in humans. Research in men focuses on its role in improving sperm quality and erectile function, rather than organ size.
