Horny goat weed is a botanical that has also been used traditionally in Japan. This herb is also used for disorders of the kidneys, joints, liver, back, and knees. Horny goat weed’s most common use is as an aphrodisiac. Through research, horny goat weed has been found to have testosterone-like effects. It stimulates sexual activity for both men and women, increases male sperm production, stimulates the sensory nerve endings, and increases overall sexual desire.

Mice treated with a horny goat weed preparation produced “apparent effects on the improvement of sexuality.” It was also shown to improve their sperm-producing capability.
