The Claim

Ashwagandha root extract (ARE) at 300 mg twice daily for 8 weeks increases semen volume by approximately 25.6%, sperm count by 47.7%, and normal sperm morphology by 18.7% in healthy men aged 30–50 years with mild sexual dysfunction and low-normal sperm parameters.

In plain English

In healthy men aged 30-50 with mild sexual dysfunction and low-normal sperm parameters, taking 300 mg of Ashwagandha root extract twice daily for 8 weeks increases semen volume by 25.6%, sperm count by 47.7%, and normal sperm morphology by 18.7%.

See the scientific wording

Ashwagandha root extract (ARE) 300 mg twice daily for 8 weeks improves semen volume by approximately 25.6%, sperm count by 47.7%, and normal sperm morphology by 18.7% in healthy men aged 30–50 years with mild sexual dysfunction and low-normal sperm parameters, suggesting potential benefits for male fertility.

Why this might work

Ashwagandha root extract works in two ways to improve sperm. First, it acts like a key that fits into special locks in the brain, telling it to release a signal that wakes up the testicles. Second, it lowers stress hormones that normally dampen that signal. With the signal strong, the testicles produce more testosterone and make more and better sperm. This leads to bigger semen volume, more sperm, and healthier-shaped sperm.

    The study gave men with mild fertility problems ashwagandha extract or a fake pill, and found that those taking the herb had about 26% more semen, 48% more sperm, and 19% more healthy-shaped sperm, which matches the claim.
