不同的生理、心理和生活模式等因素都能夠引起陽痿的發生， 根據有效的統計， 有75%的人是由於身體自身的因素直接導致陽痿， 而心理和生活模式兩種因素相對不易引起陽痿。 然而， 一種最為常見的誤解是， 陽痿僅在男性性能力的高峰期之後發生， 也就是說男性在此之後患有陽痿的可能性會增加， 但是一些年輕的或是缺乏性經驗的人也會發生陽痿。
以下因素可以導致陽痿的發生：
第一、糖尿病；
第二、激素失調；
第三、神經系統疾病；
第四、心臟與肝臟問題；
第五、靜脈漏；
第六、吸煙和飲酒；
第七、高血壓；
第八、肥胖；
第九、高膽固醇症。

It is estimated that 75% of all impotence cases result directly from physical problems, with psychological complications and lifestyle factors less likely causes. A common misunderstanding is that impotence affects men only when they are past their sexual peak. The likelihood of men suffering from impotence later in life does increase, but it can also occur for men who are both younger and less sexually experienced. Impotence may arise because of the following reasons.
Diabetes
Hormone imbalance
Neurological conditions
Heart and liver problems
Venous leak
Smoking and alcohol consumption
High blood pressure
Obesity
