Panax ginseng has a long history of traditional use for enhancing vitality and sexual function, and recent scientific studies have explored its effects on testosterone levels. Several animal and human studies suggest that Panax ginseng may have a modest positive effect on testosterone production and related sexual function parameters. For example, some randomized controlled trials have reported increases in serum testosterone or improvements in erectile function in men supplemented with Panax ginseng extract. Proposed mechanisms include modulation of the hypothalamic-pituitary-gonadal axis and improved nitric oxide synthesis, both of which can influence testosterone levels and sexual health. However, the overall quality and consistency of human evidence remain limited. Many studies suffer from small sample sizes, short durations, or methodological weaknesses, and not all report significant changes in testosterone. Major clinical reviews generally conclude that while Panax ginseng shows potential as an adjunct for male sexual health and may slightly influence testosterone, the evidence is not strong enough to consistently support its use as a primary treatment for low testosterone. Therefore, while there is some scientific validation for its use in this context, the strength of the evidence is rated as moderate to low.
