[ XXXX among Icelandic males 1986-1991.]

@entity1 @entity323 @entity251 @entity6126
The estimated prevalence of @entity323 in western societies approximates 7%. A retrospective descriptive study was performed on 282 Icelandic males (mean age 53.5 years, range 19-79) referred for evaluation of @entity323 during the period 1986-1991. Diagnostic modalities included measurements of nocturnal penile tumescence (NPT) and penilebrachial index (PBI), hormonal profile and cavernosography. In 55% the NPT was abnormal. In contrast, only 8.2% of PBI was abnormally low. By logistic regression abnormal NPT results correlated with increasing age. Measurements of hormonal profile was performed in 73.4% of the @entity1 . @entity251 was found to be below normal in 12.1%. However, primary or secondary @entity6126 was only found in 3.9% and elevated prolactin in 2.8%. By cavernosography, venous leakage was demonstrated in 3.2% of the @entity1 and subsequently ligation of the dorsal penile vein was performed. A trial of @entity251 treatment was given in 39.4% of the @entity1 . @entity323 is a common complaint among @entity1 . Psychological factors predominate in young @entity1 and the contribution of somatic etiologic factors increases with age. In the majority of @entity1 relatively simple studies can give useful information on the etiology of @entity323 .
