不同的生理、心理和生活模式等因素都能够引起阳痿的发生，根据有效的统计，有75%的人是由于身体自身的因素直接导致阳痿，而心理和生活模式两种因素相对不易引起阳痿。然而，一种最为常见的误解是，阳痿仅在男性性能力的高峰期之后发生，也就是说男性在此之后患有阳痿的可能性会增加，但是一些年轻的或是缺乏性经验的人也会发生阳痿。
以下因素可以导致阳痿的发生：
第一、糖尿病；
第二、激素失调；
第三、神经系统疾病；
第四、心脏与肝脏问题；
第五、静脉漏；
第六、吸烟和饮酒；
第七、高血压；
第八、肥胖；
第九、高胆固醇症。

There is various physical, psychological and lifestyle factors that can all contribute to impotence. 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
High cholesterol levels
