Background: Alcohol Use Disorder is quite prevalent in general population. Sexual dysfunction in alcoholics is unrecognized and not reported by patients. Moreover sexual dysfunction can lead to stress which can further increase the consumption of alcohol and it can lead to poor quality of life. Objectives: To study the prevalence of sexual dysfunction and quality of life among male patients of Alcohol Use Disorder Methods: This was an observational, cross sectional, single-centered, interview based study of total 100 consecutive male patients aged 20-50 years admitted in psychiatry ward & coming to psychiatry OPD of Sir.T.Hospital, Bhavnagar. Interview was taken for diagnosis of Alcohol Use Disorder using DSM- 5(Diagnostic and Statistical Manual of Mental Disorders-5) Criteria. Every patient was assessed by proforma containing demographic details, questionnaires of SAD-Q (Severity of Alcohol Dependance), CSFQM-C ( Changes in Sexual Functioning Questionnaire – Male Clinical Version ) & WHOQOL BREF(World Health Organization Quality Of Life). Statistical analysis was done with graph pad in stat version 3.06(San Diego, California US). Proportion of participant was compared by using chi-square test, while scores of CSFQ-M-C, SAD-Q, WHOQOL BREF were compared by using Mann Whitney test. A p value of <0.05 was considered statistically significant. Results: Frequency of sexual dysfunction among male patients of alcohol use disorder was 70%. Among the domains of sexual dysfunction; the highest frequency was seen for dysfunction in desire/frequency (84%), followed by premature ejaculation (82%), problems in pleasure (80%), difficulty in erection (68%) & least was decrease in libido (64%). Sexual dysfunction was not dependent on the amount( p value=0.1916), duration(p value=0.7038) & severity of alcohol dependence (p value=0.128). The quality of life was poor among patients with alcohol use disorder & it was dependent on severity of alcohol dependence ( p value= 0.0009, 0.0014, 0.0014, 0.0007) Conclusion: Sexual Dysfunction had no correlation with the amount, duration of alcohol intake & severity of alcohol dependence.
