Smoking and Erectile Dysfunction
While smoking rates in the United States have declined over the last few decades, the Center for Disease Control & Prevention reports that 17.8% of men over the age of 18 currently smoke cigarettes.
There are numerous studies that have documented improvement in erectile function when smoking is stopped. One study looked at a cohort of men who were all enrolled in an 8-week smoking cessation program. They were given a nicotine transdermal patch and counseling. After the treatment, the group that quit smoking reported significant improvement in erectile function. This was true even among the men that were long-time smokers.
If you are having trouble quitting smoking on your own, take time to schedule an appointment with your primary care physician who can help you learn about various options available to you.
