The Vasoconstrictor Nicotine Causes Impotence in Men that Smoke..

December 31, 2007 - The Vasoconstrictor Nicotine Causes Impotence in Men that Smoke.. Emerging research shows that men who smoke a pack-a-day are almost 40% more likely to struggle with erectile (ED, impotence) dysfunction than men who don't smoke. In a study (published in Tobacco Control) of more than 8,000 Australian men between the ages of 16 and 59 found that those that smoked less than a pack a day had a 24% increase risk of erectile problems. And as the number of cigarettes smoked went up, so too, did the chances of erectile dysfunction. A study in the American Journal of Epidemiology, found that male smokers in their 40s were more likely to experience erectile difficulties than older nonsmoking males. ( "Men Who Smoke Prone to Impotence" by Serena Gordon, HealthDay Reporter, Medical College of South Carolina, 12/30/2007) It is also known that middle-age men who are heavily exposed to secondhand smoke have nearly twice the risk of impotence as those who breathe clean air. ( "Want Better Sex? Steer Clear of Smoke" (of Nicotine) By John Reinan, HealthScout Reporter, 10/29/2000) A number of studies have shown that nicotine levels resulting from the use of smokeless tobacco are either the same or even higher than with tobacco smoking. (Maximum levels of nicotine were similar but, because of prolonged absorption, overall nicotine exposure was twice as large after single exposures to smokeless tobacco compared with cigarette smoking (Benowitz et al., Clin Pharmacol Ther. Jul;44(1):23-8, 1988)
