A disfunção erétil é um problema de saúde que condiciona a qualidade de vida de muitos homens. Para além das abordagens médicas, tem sido atribuído um papel cada vez mais importante aos fatores cognitivo-afetivos implicados nesta dimensão da resposta sexual masculina. Apesar de já existirem estudos realizados neeste campo, ainda são poucos os que comparam em laboratório, homens sem disfunção erétil e homens com disfunção erétil. Neste estudo, procurou-se investigar de que forma se diferenciam os homens sem disfunção erétil, dos homens com disfunção erétil, no que diz respeito à propensão para a excitação e inibição sexual, bem como à resposta sexual subjetiva e fisiológica, e ao tipo de pensamentos e emoções vivenciados durante a exposição a estímulos de natureza sexual em contexto laboratorial. Foi ainda investigada a interferência (efeito Stroop) cognitiva despoletada por palavras de cariz sexual. Este estudo contou com a participação de 22 homens com disfunção erétil e 20 homens sem disfunção erétil, avaliados no SexLab. Os resultados encontrados revelaram que os homens com disfunção erétil apresentam maior propensão para a inibição sexual, bem como níveis significativamente inferiores de resposta sexual subjetiva e fisiológica e menos pensamentos de cariz sexual face à exposição a estímulos eróticos em contexto laboratorial Erectile dysfunction is a health problem that affects the quality of life of many men. In addition to medical approaches, it has been assigned an increasingly important role to cognitive-affective factors involved in male sexual response. Despite the accumulated knowledge in this field, there is a scarcity of studies comparing cognitive-emotional processes and sexual responses of men with and without erectile dysfunction in the laboratory. In this study, we sought to investigate how men without erectile dysfunction differ from, men with erectile dysfunction, with regard to the propensity for sexual inhibition and excitation as well as to the subjective and pshysiological sexual response, and the nature of sexual thoughts and emotions during exposure to sexual explicit material in the laboratory. We also investigated the cognitive interference (Stroop effect) triggered by words associated to sexual context. This study had the participation of 22 men with erectile dysfunction and 20 men without erectile dysfunction, evaluated in the SexLab. The results showed that men with erectile dysfunction present higher propensity for sexual inhibiton as well as significantly lower levels of subjective and pshysiological sexual arousal and less sexual thoughts during exposure to erotic stimulus in the laboratory.
