Abstract

Background: Erectile dysfunction (ED) along with infertility are important health issues, which affects negatively the quality of life, couple’s relationship and emerging as an early marker for evaluation of decreased general health status

Purpose: This pilot study was to investigate the prevalence and risk factors of erectile dysfunction (ED) in men of infertile couples from an in vitro fertility center in northern Vietnam.

Methods: A total of 138 men of infertility couples were enrolled in this study from January to May 2018. The International Index of Erectile Function questionnaire scale was used to access the severity of ED and several related factors were also collected to determine risk factors. 

Results: The prevalence of ED among men of infertile couples was 18.1%, including 13 mild ED (9.4%), 7 mild to moderate ED (5.1%), 2 moderate ED (1.4%) and 1 severe ED (0.7%). Using logistic regression analysis, we showed that risk factors associated ED were smoking above 5 pack/years with OR = 3.16, CI = 0.98 – 10.18, p = 0.05; not graduating junior high school, OR =  5.11, CI = 1.11 – 23.8, p = 0.03, and azoospermia, OR = 7.55 , CI = 2.18 – 26.16, p = 0.001. We observed relatively high OR in men with smoking under 5 pack/years (OR = 2.51), abnormal semen analysis (hypospermia, oligozoospermia, asthenozoospermia, or teratozoospermia) (OR=2.36), but there was not significant differences compared with reference group.

Conclusion: The prevalence of ED among men of infertile couples in this study was higher than infertile men.  Low level of education, smoking for a long period, and azoospermia were the main risk factors of ED in men. Further large-scale studies are needed to extend the results.
