Background: Individuals suffering from diabetes mellitus are at higher risk of all forms of sexual dysfunctions, but there is hardly any study in India that discussed all aspects of sexual activity in diabetic patients. Hence, the current study was conducted to estimate the prevalence of the sexual disorder in diabetic patients. Materials and methods: One hundred nine diabetic men were selected, who fulfilled the inclusion criteria and assessed by the International Index of Erectile Function-5 (IIEF-5) questionnaire. Result: The prevalence of erectile dysfunction (ED) was 89.9%, out of which 58.16% reported spontaneously with maximum (62.4%) having severe ED, andthe IIEF-5 score provided by patients themself and their spouses was statistically significant (p-value = 0.000). The hypoactive sexual desire and decreased libido were 25.7% and 42.2%, respectively. A total of 68.8% of participants failed to attain orgasm, 56.9% of participants had premature ejaculation but 20.2% had delayed ejaculation, and 61.47% had all three of erection, ejaculation, and orgasm problems. Conclusion: This study concluded that nine out of ten diabetic men were suffering from ED and only interviewing the male sexual partner is sufficient for the evaluation of ED and also concluded that ED is not so much social stigma nowadays. Other sexual dysfunction should be addressed for better sexual satisfaction outcomes.
