Twenty men, aged 50 to 75 years (mean, 67 years), suffering from benign prostatic hypertrophy received 160 mg of a lyposterolic extract of Serenoa repens, twice daily for 30 days. Before and at the end of treatment, plasma levels of testosterone, follicle-stimulating hormone, and luteinizing hormone were determined. No changes in plasma hormone levels occurred as a result of treatment. It is concluded that Serenoa extract, which is useful in the treatment of benign prostatic hypertrophy, does not act via systemic changes of hormone levels.
20名年龄在50至75岁（平均67岁）之间患有良性前列腺增生的男性，每天两次服用160毫克锯叶棕果实提取物，持续30天。在治疗前和治疗结束时，测定了血浆中睾酮、促卵泡激素和促黄体生成素的水平。治疗后血浆激素水平未发生变化。得出的结论是，对治疗良性前列腺增生有用的锯叶棕提取物并非通过激素水平的全身性变化起作用。
