Ashwagandha root extract at a dosage of 300 mg twice daily for 8 weeks significantly improves five domains of male sexual function (sexual cognition/fantasy, sexual arousal, sexual behavior/experiences, orgasm, and sexual drive/desire) compared with placebo in healthy adult men with low sexual desire, with all differences reaching statistical significance (p < 0.0001).

Ashwagandha extract makes the brain send a signal to the testicles to produce more testosterone. It also contains tiny plant chemicals that look like testosterone and can attach to the same receiving spots in the body. Testosterone is the main hormone for male sexual function. It works on the brain to increase sexual thoughts and desire, on the body to improve arousal and performance, and on the nerves to help with orgasm. By raising the level of androgen activity in the body, ashwagandha improves all five areas of sexual function.
