Frequency of Erectile Dysfunction in Patients with Type 2 Diabetes Mellitus Presenting with Peripheral Neuropathy at a Tertiary Care Hospital

Abstract

Background: Erectile dysfunction (ED) is notably prevalent among patients with type 2 diabetes mellitus (T2DM), especially those suffering from peripheral neuropathy. The condition significantly impacts the quality of life and is often exacerbated by diabetes-related complications. Objective: This study aims to ascertain the frequency and severity of ED among patients with T2DM and peripheral neuropathy, and to examine the association between ED and variables such as age, duration of diabetes, and glycemic control. Methods: A prospective cohort study was conducted at the Baqai Institute of Diabetology and Endocrinology, Karachi, from July 2021 to September 2022. We included 115 male patients aged 35-65 years with T2DM and diagnosed peripheral neuropathy. ED was assessed using the Urdu version of the International Index of Erectile Function-5 (IIEF-5) questionnaire. Demographic details, medical history, and laboratory results were collected and analyzed using SPSS version 25. Statistical tests included chi-squared and one-way ANOVA, with a significance level set at p<0.05. Results: The mean age of the participants was 50.97 ± 7.21 years, and the average duration of diabetes was 9.37 ± 6.56 years. The mean IIEF-5 score was 14.33 ± 6.0, indicating moderate ED. Severe ED was observed in 20% of the participants, moderate ED in 19.1%, and mild to moderate ED in 28.7%. The study found a significant association between the duration of diabetes and ED severity (p < 0.001), while age and HbA1c levels did not show a significant correlation with ED status. Conclusion: ED is highly prevalent and severe among patients with T2DM and peripheral neuropathy, with disease duration being a significant predictor of ED severity. These findings underscore the need for early screening and targeted interventions in this population.
