Men who smoke have a significantly higher risk of developing impotence (erectile dysfunction) than non-smokers. This risk increases the longer you smoke and the more cigarettes you smoke.1,2
Erectile dysfunction is the inability to achieve and maintain an erection sufficient for satisfactory sexual performance. 3 Erectile dysfunction can impact on the ability of men to have a full sex life and may inhibit their ability to have a child. 4
There are a number of causes of erectile dysfunction. The majority of cases are due to physical causes, with circulatory and vascular problems being the most common physical cause. 4 Smoking can contribute to the development of atherosclerosis which occurs when there is narrowing and clogging of the arteries reducing blood supply. 5 This includes decreasing blood supply to the penis. In addition, the nicotine in cigarette smoke can result in vasospasm (temporary constriction of the penile arteries) which can also affect blood flow to the penis. 4,5,6 Also see the fact sheet ‘Smoking clogs your arteries’ for more information on atherosclerosis.
There is evidence to suggest that cigarette smoking exacerbates other risk factors for erectile dysfunction, such as coronary heart disease and diabetes. 4,6
Cigar smoking and exposure to environmental tobacco smoke are also associated with erectile dysfunction. 5,6
Almost one in 10 Australian men aged 16-59 years report having experienced erectile dysfunction that lasted a month or more. 1 Compared to non-smokers, men who smoked up to 20 cigarettes a day were 24% more likely to experience erectile dysfunction. For men who smoked a pack or more of cigarettes daily, this risk increased to almost 40%. 1
Quitting smoking will reduce your chance of developing erectile dysfunction. 5 For those who already experience erectile dysfunction, it is uncertain whether quitting smoking will be helpful. Some studies indicate that quitting smoking can lead to recovery if there is a limited period of smoking. 5 Reduce your risk by never starting smoking or quit smoking as soon as possible if you already smoke. 7
Smoking may also affect the development and quality of sperm, decrease the sperm count and reduce the volume of semen. 5 Toxins found in tobacco smoke such as cadmium, nicotine, benzopyrene and related by-products can damage the genetic material in sperm cells. 4
While many studies have not shown a reduction in male fertility associated with smoking, 8 there is emerging evidence that the damage to sperm may affect male reproduction. 9
Studies suggest that children of fathers who smoke have an increased risk of developing childhood cancers, possibly as a result of the damage to the father’s sperm. 9,10 While not yet conclusive, there is also some emerging evidence that the repercussions for children of fathers who smoke may extend beyond cancers. 11
Cigarette smoking is associated with an increased risk of developing invasive penile cancer. This risk is approximately four times more than for non-smokers. 12 While penile cancer is rare, in Australia, 30% of penile cancer in men is estimated to be attributed to smoking. 13

Tobacco use reduces not only your life expectancy but your quality of life. Many medical conditions caused by smoking can result not just in death, but in living for years with disabling health problems.
Quitting smoking can be one of the most difficult, yet rewarding things a person can do. Most smokers' say they would like to quit, and may have tried at least once. Some are successful the first time, but many other people try a number of times before they finally give up for good.
