Abstract
The study was conducted in Qaliobia Governorate on 252 married men; the study was carried out during 2009-2012.
The IIEF-15 questionnaire was fulfilled included questions about age, occupation, height, weight, fertility, presence or absence of marital problem, general questions on self-reported health, systemic diseases especially diabetes mellitus, cardiovascular problems and hypertension as well as, chronic use of drugs, smoking and alcohol.
The study extended to evaluate most of the sexual problems, not only erectile function, but also intercourse satisfaction, orgasmic function, sexual desire and the overall satisfaction for each age group. Then, each item was further classified into normal, mild effect, moderate effect or severe effect.
Erectile function showed a significant correlation in groups I and III with negative correlation (r = -0.303& -0.358), while groups II & IV had insignificant correlation (-0.003 & 0.22), respectively with P value of >0.05 in both groups. However, the overall significant difference in all groups showed statistically significant correlation (r = -0.351, P <0.05). This indicated that the erectile function decreased with age.
Intercourse satisfaction and orgasmic function domains showed significant correlations only in total age groups (-0.463& -0.397) with P value of <0.01 in both domains.
Sexual desire showed significant correlation in group I (P <0.05) and in total age groups (P <0.01), while the overall satisfaction was significant only in total age groups (r = -0.302, P <0.05).
Some risk factors of ED as smoking, diabetes, and hypertension showed significant correlation with erectile dysfunction, they showed P value of <0.05, <0.01 and <0.05, respectively (diabetes had the priority).
The link between long-term cigarette smoking and erectile dysfunction is robust and indicates that cigarette smoking is an independent risk factor for introducing vasculogenic ED.
Diabetes can also cause serious problems. It exacerbates erectile dysfunction by making blood vessels less elastic. Such blood vessels cannot dilate fully and thus restrict blood flow during an erection. Diabetes also deteriorates nerve viability, thus decreasing the sensitivity of the penis. Both effects are magnified when the condition has been present or poorly controlled for many years. Approximately fifty percent of men with diabetes have erectile dysfunction, and the percentage increases with age.
Over time, high blood pressure damages the lining of blood vessels and causes arteries to harden and narrow (atherosclerosis), limiting blood flow. This means less blood is able to flow to the penis. For some men, the decreased blood flow makes it difficult to achieve and maintain erections often referred to as erectile dysfunction. The problem is fairly common, especially among men who are not treating their high blood pressure.
