Although not everyone who supplements with tongkat ali wants to increase their fertility, it is worth mentioning that tongkat ali’s hormonal support benefits also promots normal sperm quality. Sperm quality, measured by volume, concentration, and motility, can impact male fertility. 
That said, if you’re a middle aged male who is experiencing the symptoms of andropause and feel it’s time to put a spring back into your step, consider supplementing with tongkat ali. The research is positive and do not indicate any negative side effects. If you combine herbal support with a healthy diet and regular exercise, you may have a winning formula.
It’s not your fault. Your testosterone has been declining by roughly 1% per year, every year since you were 30. You now have a choice to make. You can either continue down the path of aging and going quietly into the night, or you can be proactive and regain that edge with Tongkat Ali.
A 2012 study out of Malaysia consisted of seventy-six men, only 35% of whom had normal testosterone levels. After one month of supplementing with tongkat ali, the number of men in the group with normal testosterone levels jumped to over 90%.
