Epimedium sp. is famous for its potency as sexual enhancer and five species of Epimedium
brevicornum, E. sagittatum, E. pubescens, E. koreanum, and E. wushanense were recorded as
Epimedium Herba (Yin Yang Huo) in Chinese Pharmacopeia. The aim of this study was to
evaluate the potential efficacy of E. brevicornum as remedy for sexual dysfunction and
infertility. For preparing this manuscript, we searched in all accessible resources (PubMed,
Science direct, Wiley, Springer, and Google), books, thesis, and pharmacopeia. There are
different traditional prescriptions from E. brevicornum, which are used for treatment of
impotence and sexual disorders. Although, there is no clinical study on efficacy and safety of
E. brevicornum on sexual functions, but animal and experimental analysis exhibited that E.
brevicornum is and estrogenic plant and its flavonoid glycosides are inhibitors of
phosphodiesterase 5 (PDE 5) and improved the erectile dysfunction, libido, impotence, sperm
quality and fertility . Due to the lack of clinical study on efficacy of E. brevicornum,
designing the human clinical study on safety and efficacy of standard E. brevicornum can be
the subject of future studies.
