Purpose: We estimated the association of sildenafil use with erectile funct
ion, relationship with sexual partner, functional status and emotional well
-being in men with erectile dysfunction.
Materials and Methods: Letters were mailed to eligible patients at a univer
sity hospital urology and internal medicine clinic, and university affiliat
ed community primary care clinics by the primary care provider or urologist
inviting them to participate in the study. Of the eligible sample 124 men
(53%) completed and returned a survey, including 85 who reported current si
ldenafil use. Change scores in these patients were calculated using the Int
ernational Index of Erectile Function, marital interaction scale from the C
ancer Rehabilitation Evaluation System Short Form, 5-item emotional well-be
ing scale of the RAND 36-Item Health Survey and 12-Item Short Form Health S
urvey.
Results: Sildenafil users reported an 88% increase in erectile function sco
res, 60% increase in overall sexual satisfaction and 36% increase in interc
ourse satisfaction related to the use of sildenafil (p <0.001). Of the resp
ondents 38% indicated that using sildenafil had definitely improved quality
of life. Likewise 29% of respondents indicated that using sildenafil had d
efinitely improved the relationship with their partner. With sildenafil the
re was a statistically significant improvement in the scores of erectile an
d sexual function (p <0.001), sexual partner relationship (p = 0.007) and e
motional well-being (p <0.001). In a multivariate model improved erectile f
unction and sexual partner relationship were each significantly associated
with improved emotional well-being (R-2 = 0.20, p <0.001).
Conclusions: Sildenafil users reported significant improvements in erectile
and sexual function that were associated with positive changes in emotiona
l well-being and the sexual partner relationships with their sexual partner
.
