Though not found prostate cancer 95 to be significant, passive smoking exposure prostate cancer 95 trended toward a significant risk of ED.
While this study design is subject to recall bias, it may provide important information when quantifying risk of ED due to smoking exposure. Positive dose-response association between quantity and duration of smoking with risk of ED was confirmed in a meta-analysis of observational epidemiologic studies (Prostate cancer 95 29).
The investigators found an Incremental increased risk of ED per 10 cigarettes smoked per day and 10 years of smoking, by 14% and 15%, respectively.
An Prostate cancer 95 individualized inverse dose-response relationship was seen in male smokers undergoing polysomnographic assessment of nocturnal penile tumescence (NPT), where the Prostate cancer 95 highest consumers of cigarettes (>40 cigarettes per day) had Birra e prostata the fewest minutes of nocturnal tumescence and detumesced fastest (30). At prostate cancer 95 a molecular and cellular level in prostate cancer 95 the animal model, cigarette smoking (CS) Prostate cancer 95 is linked to significantly higher Markers of Prostate cancer 95 oxidative stress and cavernosal tissue apoptosis (31). CS exposed rats were noted to Prostate cancer 95 have significantly lower expression of cavernosal neuronal nitric oxide synthase (nNOS) and decreased endothelial and smooth muscle content, supporting the role of endothelial dysfunction in pathophysiology of ED (12).
The effect of prostate cancer 95 smoking cessation on erectile function has also been examined.
Prospectively studied a sample of men with ED and smoking as their only risk factor; excluded were men with other risk factors for ED such as diabetes, hypertension, dyslipidemia, peripheral vascular disease, psychiatric disorders, and renal failure.
At baseline, severity of ED was found to be significantly correlated to duration of exposure in pack-years (32). At follow-up 1 year after smoking cessation, patients who successfully stopped smoking (ex-smokers) had Prostate cancer 95 a 25% improvement in erectile function, prostate cancer 95 while men who continued (current smokers) did not improve.
Additionally, a larger proportion of current smokers (7%) than ex-smokers (2.5%) had worsening of their baseline ED. This study suggests a large degree of stabilization or improvement in ED after smoking cessation. These results were corroborated in a randomized controlled study of Chinese men enrolled in a nicotine replacement therapy (NRT) program with or without counseling. Six months after enrollment, patients who successfully quit smoking were more likely to have improvement in erectile function compared to persistent smokers (53.8% vs. 28.1%, P3,000 kcal/week significantly reduced the likelihood of severe ED (IIEF-5 600 mL/week) (6).
Furthermore, in a large, multi-national epidemiologic study, heavy and no prostate cancer 95 alcohol consumption were associated with higher risk Prostate cancer 95 of ED as compared to moderate prostate cancer 95 alcohol intake (1 to 7 drinks per week), though not significantly (48).
On the contrary, in the HPFS study, there was no change in relative risk Prostate cancer 95 of ED across all categories of alcohol consumption (8). In the rat model, chronic alcohol consumption leads to an upregulation of endothelin-1 (ET-1) which acts as a vasoconstrictor in the corpora cavernosa (CC). Following Prostate cancer 95 electrical stimulation of the major pelvic ganglion, ethanol treated rats demonstrated significantly reduced erectile response as measured by maximal intracavernosal pressure/mean arterial pressure (ICP/MAP) (49). These results provide some basis for investigation in human subjects. Whether changes in Prostate cancer 95 CC ET-1 levels are sustained after ethanol Cessation warrants investigation. Illicit drug use was studied in a cross-sectional trial of Taiwanese detainees (N=701, mean age 33.8 years) with a history of drug abuse versus controls (N=196) (50). Heroin, amphetamine and MDMA (“ecstasy”) were the most commonly reported drugs of abuse in prostate cancer 95 this detainee population. Over one third (36.4%) of drug abusers were found prostate cancer 95 to have ED as reported by IIEF-5 score, with 10% reporting severe ED.
