We conducted a telephone survey during 2001–2002 to investigate sexual behavior, sexual dysfunction, and related help-seeking behavior in five Anglophone countries. In total, 5,998 individuals (2,992 men and 3,006 women) aged 40–80 years in the United States, Canada, the United Kingdom, Australia, and New Zealand completed the survey. The majority of subjects were sexually active, and although many men and women had experienced sexual dysfunctions, few had sought medical care for these dysfunctions. Further investigation is required to determine whether national differences in the prevalence of sexual dysfunctions are due to genetic predisposition, health factors, cultural perception or socioeconomic situation.
