Does Ashwagandha Lower Testosterone?
Quick Answer
Nope, other way around. Ashwagandha actually raises testosterone. Multiple studies show 10-22% increases in men, especially stressed or active ones. It works by lowering cortisol, which otherwise suppresses T. This is one of the few supplements with actual testosterone data behind it.
Key Points
- RAISES testosterone, doesn't lower it
- 10-22% increases in clinical trials
- Works through cortisol reduction
- Stressed guys see the biggest effects
- KSM-66 and Sensoril have the research
Detailed Answer
Where did this myth come from? No idea. The research says the opposite.
Actual data: - 2019 study: 14.7% testosterone increase after 8 weeks (KSM-66) - 2015 study: 10-22% increases in men with fertility issues - 2010 study: Testosterone up, cortisol down in stressed adults
Here's why it works: When you're chronically stressed, cortisol goes up. High cortisol suppresses testosterone. Ashwagandha is an adaptogen that lowers cortisol. Lower cortisol = testosterone can normalize or increase.
The catch: If you're already low-stress with optimal T, don't expect magic. The effects are most pronounced in guys who are stressed out or have suboptimal testosterone to begin with.

8-12 weeks for measurable testosterone changes in studies. Cortisol might drop sooner (a few weeks), then T follows as stress hormones normalize. Be patient.
