WHITE PLAINS, NY — September 24, 2002 — announced today that nearly 60% of products failed to pass its independent Product Review of Sexual Enhancement Supplements. Sexual dysfunction is estimated to affect 43% of women and 31% of men in the U.S. according to an article published in the Journal of the American Medical Association in 1999. However, no prescription medication is available for sexual dysfunction for women and Viagra, an effective drug for erectile dysfunction in men, is expensive and has potential side effects. A variety of non-prescription, sexual enhancement supplements is marketed in the U.S.'s review assessed the clinical evidence for more than twenty ingredients used in these supplements and evaluated 22 products containing the popular ingredients L-arginine, yohimbe, and epimedium (horny goat weed).

Eleven of the products evaluated failed to meet FDA labeling requirements. One product, for example, did not list the plant parts used, while another product indicated that it was made from yohimbe "root" rather than the appropriate part — bark. The remaining eleven products underwent further laboratory analyses. Among these, one product contained only 1% of its claimed amount of yohimbe. Another product was found to contain only 45% of the expected marker compound for a key ingredient — epimedium.

Only 9 of the 22 sexual enhancement products purchased passed the review. Commenting on the disturbing results, Tod Cooperman, M.D., President of said, "Viagra's success has spawned a plethora of alternative therapies marketed for sexual dysfunction. People interested in using these products, however, need to view them critically — as the effectiveness of most ingredients has not been well proven and many products are poorly made."
