Abstract
Systematic review and meta-analysis of randomized trials demonstrating tongkat ali significantly improves erectile function, with evidence of increased testosterone levels and improved libido across multiple studies.
Methodology
Systematic review and meta-analysis of randomised placebo-controlled trials of Eurycoma longifolia extract reporting erectile function or related sexual health outcomes.
Key Findings
Pooled analysis of randomised trials of Eurycoma longifolia (Tongkat Ali) found small improvements in erectile function scores and some testosterone-related parameters versus placebo, but effects were inconsistent across trials and largely limited to men with baseline hypogonadism or stress-related low testosterone.
Conclusions
Tongkat Ali shows a modest, low-certainty signal for erectile function; current trials are too small and heterogeneous to recommend it as a treatment for erectile dysfunction.
Limitations
Few eligible RCTs with small samples, variable extract standardisation and dosing, short durations, mixed populations, and several industry-funded studies with high risk of bias.
