Answer

Sexual dysfunction is highly prevalent in men and women. In the MMAS, 52% of the respondents reported some degree of erectile difficulty. Complete ED, defined as (1) the total inability to obtain or maintain an erection during sexual stimulation and (2) the absence of nocturnal erections, occurred in 10% of the respondents. Mild and moderate ED occurred in 17% and 25% of responders, respectively. [15]

Although the rate of mild ED in the MMAS remained constant (17%) in men aged 40-70 years, the number of men reporting moderate ED doubled (17-34%) and the number of men reporting complete ED tripled (5-15%). If the MMAS data are extrapolated to the US population, an estimated 18-30 million men are affected by ED. [50]

In the National Health and Social Life Survey (NHSLS), a nationally representative probability sample of men and women aged 18-59 years, 10.4% of men reported being unable to achieve or maintain an erection during the past year. [51] There is a striking correlation with the proportion of men in the MMAS who reported complete ED.

Studies conducted around the world report similar risk factors and similar prevalence rates for ED. [52, 53]
