OBJECTIVETo assess the mean age of sexual activity termination, the prevalence of erectile dysfunction (ED), and their related factors in the old male population in Beijing.

METHODSWe included in this study 764 males aged over 60 years old received in the health examination clinic and investigated the prevalence of ED and the related factors using the sexual health assessment resource (SHARE) and IIEF-5 questionnaires.

RESULTSThe average age of sexual activity termination (no sexual intercourse in over 2 years) was 68.4 +/- 5.2 years among the subjects. The prevalence of ED was 89.4% , of which the rates of mild, moderate and severe ED and non-sexuality were 6.7, 18.6, 28.4 and 35.7% , respectively. Those who had no sexual intercourse for over 2 years because of severe ED accounted for 26.8% among the 60-64 years old males and more than 50% in the >70 yr group. The main risk factors for ED-induced sexual activity termination included age, diabetes, cardiovascular and cerebrovascular diseases, obesity, and low urinary tract symptoms (LUTS).

CONCLUSIONED is a common problem as well as the main risk factor for sexual activity termination, and age and general health status are significantly associated with the prevalence of ED among aging males.
