<Tongkat Ali, also known as Eurycoma longifolia, has clinical support for increasing testosterone levels.
To test Tongkat Ali benefits in men between the ages of 30 and 55 years old, a randomized, double-blind, placebo controlled, parallel group study was carried out. The 12-week study in 109 men between 30 and 55 years of age consisted of either treatment of 300 mg of water extract of Tongkat Ali or a placebo.
Results were evaluated by the following:
- Quality of Life investigated by SF-36 questionnaire
- International Index of Erectile Function (IIEF)
- Seminal Fluid Analysis (SFA)
- Fat Mass
- Safety Profiles
The Tongkat Ali group significantly improved in quality of life scores. The Tongkat Ali group showed higher scores in erectile function, sexual libido, sperm motility, and semen volume at the end of treatment.
Subjects with BMI ≥ 25 significantly improved in fat mass lost. All safety parameters were comparable to placebo.
In conclusion:
Tongkat Ali treatment results in improved erectile function, improved sperm parameters, and improved quality of life.
