Aim:The association between low testosterone levels and coronary artery disease in urban male population of Chennai.

Objective:To find out the effects of low testosterone levels in predisposing to CAD in males.

Study design:The study was a case control study conducted among 97 subjects(47cases and 50 controls) among the patients attending the cardiac OPD of Chettinad Hospital and Research Institute for a period of 6 months

Methodology:After obtaining consent, cases and controls are selected based on clinical history and angiographic findings.They are requested to give 5 ml of blood. Blood is collected in red topped vacutainer which should be centrifuged and the following parameters analysed.

Statistical Analysis:The statistical analysis was done using the SPSS version 21.

Result: Testosterone levels were lower in men with Coronary artery disease than normal healthy individuals and was found to be statistically significant(p<0.05).

Conclusion:A low plasma testosterone level is associated with high percent risk of development of coronary artery disease suggesting the protective effect of testosterone on endothelium
