RESUMEN
Epimedii folium is a commonly used Traditional Chinese Medicine (TCM) for warming the kidney and strengthening the yang qi. It has androgen-estrogen-like effect. It can not only directly act on sexual organs to regulate hormone levels, but also exert sex-hormone-like effect through hypothalamus-pituitary-gonadal axis. Its regulation of hormone levels is similar to that of plant hormones. At present, Epimedii folium is commonly used with other TCMs to treat diseases caused by sex-hormone deficiency, such as male spermatopenia, asthenospermia, benign prostatic hyperplasia, functional erectile dysfunction, female premature ovarian failure, perimenopausal syndrome, dysfunctional infertility during ovulation, hyperandrogenemia of PCOS patients, etc.
