Abstract: Purpose: Our purpose was to analyze sperm motility parameters in the presence of herbs.Methods: Washed sperm were incubated in either saw- palmetto (Serenoa repens, Permixon Sabal serrulatum), echinacea purpura, ginkgo biloba, St. John's wort (Hypericum perforatum), or control medium. Parameters were measured on a Hamilton-Thorn analyzed after 1, 4, 24, and 48 hr or 37 degrees C. Results: Sperm motility was inhibited at the high concentration (0.6 mg/mL) of sperm. High-concentration echinacea purpura interfered with sperm enzymes. Ginkgo did not have an antioxidant effect on sperm motility.
