Male erectile dysfunction is a common urologic disorder which can have a profound detrimental impact on a patient's quality of life. Normal erectile function represents a complex physiologic process requiring integrated synchronized function of vascular, neurologic, and musculoskeletal body systems, with significant psychologic factors playing a role as well. A breakdown in any one of these body systems can contribute to the development of erectile dysfunction. As men age, many of the same risk factors for the development of cardiovascular disease also can have a detrimental effect on the organ systems needed for good erectile function. A solid grasp of the anatomy and physiology involved in normal erectile function is important in understanding the interactions between cardiovascular disease and erectile dysfunction, and in developing new ways to effectively treat and prevent both disease processes in the future.
男性勃起功能障碍是一种常见的泌尿系统疾病，会对患者的生活质量产生深远的不利影响。正常的勃起功能是一个复杂的生理过程，需要血管、神经和肌肉骨骼系统的综合协同功能，同时心理因素也起着重要作用。这些身体系统中任何一个出现故障都可能导致勃起功能障碍的发生。随着男性年龄的增长，许多导致心血管疾病的相同危险因素也会对良好勃起功能所需的器官系统产生不利影响。扎实掌握正常勃起功能所涉及的解剖学和生理学知识，对于理解心血管疾病与勃起功能障碍之间的相互作用，以及未来开发有效治疗和预防这两种疾病过程的新方法至关重要。
