OBJECTIVES: This study assessed the quality of life associated with erectile dysfunction (ED) among the U.S. adult population both among diagnosed ED sufferers and non-sufferers. METHODS: A representative (U.S.) sample of 1,000 adults (502 males, 498 females) completed an online survey about their own (for men) or partner’s (for women in a heterosexual relationship) overall and erectile function health states and quality of life.  Health states utilities were measured using both SG and VAS questions (counterbalanced order).  RESULTS: CONCLUSIONS: The fact that males who have not been diagnosed with ED have the same utility for the ED health state as those who have been diagnosed indicates that otherwise healthy males accurately anticipate quality of life decline associated with ED.  Females with a diagnosed partner seem more willing to accept living with that partner’s ED health state.
