Clinical study of sexual dysfunction in men with type 2 diabetes mellitus

Men with diabetes mellitus have a significantly higher prevalence of erectile dysfunction than the general population. This study is planned to assess the various aspects of sexual functions like libido, erectile function and ejaculatory function in male with type 2 diabetes mellitus. Fifty male type 2 diabetic patients were included. All the patients were interviewed and examination of external genitalia performed. Penile blood flow was assessed by compression method and nocturnal penile tumescence was assessed by "stamp test". Libido was normal in 40%, erection was present in 48% and ejaculation was present in 74% of the subjects. Retrograde ejaculation was reported from 4% of patients. Early morning erection was present in 50%, orgasm was attained by 50%. Testicular sensation was absent in 20% of patients. Penile blood flow was absent in 4%. Stamp test for nocturnal penile tumescence was positive in 40% of patients. Sexual dysfunction is common in diabetic males and may be associated with peripheral neuropathy and peripheral vascular disease. In our set up, sexual dysfunction alone does not bring the patient to physician. Sexual history is to be elicited in male type 2 diabetics. Simple test like stamp test can be useful in evaluating sexual dysfunction.
