最近，有学者对既往完成的６项涉及４个不同国家的740名男性阳痿患者的研究资料进行了系统的回顾性分析，结果发现通过修正不健康的生活方式（如戒烟、进行体育锻炼）和/或使用药物以降低患者的血压、调节血脂和控制体重等可以显著改善阳痿患者的性功能。这一结果提示，遵循健康的生活方式不仅有益心脏病的防治，亦有利于男性性功能的保持与改善。

Protecting Heart May Improve Erectile Dysfunction

Cardiac drugs, lifestyle changes improve sexual function in men with ED, study shows

TUESDAY, Sept. 13 (HealthDay News) -- The lifestyle changes and medications used to reduce risk factors for heart disease may also improve sexual function in men with erectile dysfunction, according to a new study.

Researchers from the Mayo Clinic in Rochester, Minn., analyzed six previous studies from four countries involving 740 men to determine how lifestyle changes and drugs used to treat risk factors for heart disease affected the severity of their erectile dysfunction (ED).

Each study reviewed reported improvements in men's erectile dysfunction as a result of lifestyle changes and better blood lipid levels. Heart disease and ED share certain controllable risk factors, such as high blood pressure, smoking, obesity and lack of physical activity, the researchers explained.

Moreover, erectile dysfunction appears to be an indicator of heart disease, the researchers said. "Men with ED provide an opportunity to identify CV risk factors and initiate lifestyle changes," the authors wrote.

The study, published online Sept. 12 in Archives of Internal Medicine, concluded that when cardiac risk factors improved, so did sexual function in men with erectile dysfunction. When either drugs or lifestyle changes to combat heart disease were considered alone, the benefits to the men's sexual function was still significant, the researchers noted in a journal news release.
