Objective: To investigate the prevalence of ED and the associated factors in infertile males.
Methods: We continuously selected 896 infertile males present at Peking Union Medical College Hospital, Dongzhimen Hospital and the Sixth Medical Center of PLA General Hospital and evaluated the erectile function of the patients using a self-designed questionnaire and IIEF-5. We analyzed the ED-associated factors by multivariate analysis.
Results: Based on the results of questionnaire investigation, there were 416 cases of ED in the 896 infertile males (46.43%), including 23 (2.56%) severe, 38 (4.24%) moderate, 109 (12.17%) mild-moderate and 246 (27.46%) mild cases. Multivariate analysis indicated that the prevalence rate of ED was correlated positively with obesity, hypertension and diabetes, and negatively with husband-wife affection and the frequency of sexual intercourse.
Conclusions: The prevalence rate of ED is high in infertile males, mostly mild, and correlated with husband-wife affection, the frequency of sexual intercourse and some diseases.
