Substance or Alcohol abuse
Drinking alcohol on occasional times can result in symptoms of erectile dysfunction in men. The reason behind is that alcohol greatly affects all the body parts that are responsible for causing an erection. A high amount of alcohol in blood circulation lowers the hormone levels including testosterone in men. Alcohol consumption can also damage the cells present in your gonads and testes. However, even mild damage from alcohol abuse might prevent a man from getting or keeping an erection.
