The term impotence can be defined as "disturbances in sexual behavior and sexual feeling in males as evidenced by impaired or atypical genitophysiological reactions or the complete absence of such reactions." There are two main forms: erectile impotence and premature ejaculation. Differential diagnosis between "organic" and "psychogenic" impotence is very often impossible due to the fact that the causal factors of both areas can play a role in individual cases. Psychotherapy is not always necessary. Sexual counseling can be appropriate when sexual problems are the result of inadequate sex education, sexual inhibitions or minor conflicts with the partner. Depending upon the main causes for the sexual inadequacy, the specific psychotherapy is directed towards the problems in the partnership, towards the personality difficulties, or towards the sexual behavior itself. For the treatment of the latter, the behaviorally oriented therapyprogram of Masters and Johnson has been shown to be very successful.
阳痿这一术语可定义为“男性性行为和性感觉方面的障碍，表现为生殖生理反应受损或异常，或完全没有此类反应”。主要有两种形式：勃起功能障碍和早泄。由于在个别案例中，这两个方面的因果因素都可能起作用，所以往往无法对“器质性”和“心因性”阳痿进行鉴别诊断。心理治疗并非总是必要的。当性问题是由于性教育不足、性抑制或与伴侣的小冲突导致时，性咨询可能是合适的。根据性能力不足的主要原因，具体的心理治疗针对伴侣关系中的问题、人格障碍或性行为本身。对于后者的治疗，马斯特斯和约翰逊的行为导向治疗方案已被证明非常成功。
