P>Erectile dysED) is often associated with cardiovascular disorders such as hypertension, coronary heart disease, hypercholesterolaemia and diabetes mellitus. The genotypes in the GNB3 C825T, the ACE I/D and the eNOS G894T polymorphisms have been identified as genetic risk factors for cardiovascular disorders. The association between the genotypes in these polymorphisms and the risk to develop ED was analysed. In 455 German ED patients and 111 age-matched healthy controls genotyping in the candidate polymorphisms was performed after DNA extraction from whole blood. Association studies between the genotype distribution in the control group in comparison with the ED-group and age of onset of the disease as well as erectile response to intracorporal prostaglandin injection in dependence of candidate polymorphism genotype were performed using the SPSS-Software (R). Genotype distribution of the GNB3 C825T, the ACE I/D and the eNOS G894T polymorphisms was similar in the ED population and the healthy control group. The age of onset of the disease as well as the erectile response to intracorporal prostaglandin injection was independent of the genotypes in the three candidate polymorphisms. In contrast to the previous studies in this analysis, the risk to develop ED is not influenced by the genotypes in the GNB3 C825T, the ACE I/D and the eNOS G894T polymorphisms.
