[Related factors of erectile dysfunction: An analysis of 297 male patients].

Objective: To analyze the basic characteristics and related factors of ED.
Methods: Using the self-designed National Key Collaboration Platform for Impotence Disease Research, we enrolled 297 ED males at the urological clinic of the Second Hospital of Zhejiang University of Chinese Medicine from January 2015 to August 2018, and analyzed their basic characteristics, IIEF-5 scores, and erection hardness grades based on the Erectile Hardness Grading Scale.
Results: The patients were aged 21－81 years, 41.4% at the age of 31－40 years, 81.5% with a disease course of less than 5 years, 56.9% with mild ED, and 44.8% with grade-3 erectile hardness. The IIEF-5 scores were significantly lower in the patients over 60 years old than in those aged 31－40 years (13.82±5.36 vs 8.50±4.99, P < 0.05), in those with a disease course of <5 years than in those with a disease course of >10 years (P < 0.05), and in those with a poor than in those with a loving relationship (P < 0.05), but showed no statistically significant difference among those with different marital status (P > 0.05).
Conclusions: The severity of ED is related to age, course of disease and mutual affection between the partners, but not to marital status.
