Male hypogonadism is a clinical syndrome caused by testosterone deficiency which may adversely affect multiple organ functions and quality of life  .
Testosterone deficiency increases with age; an annual decline in circulating testosterone of 0.4-2.0% has been reported [2,3]. In middle-aged men, the incidence was found to be 6% . It is more prevalent in older men, in men with obesity, those with co-morbidities, and in men with a poor health status.
Decreases in testosterone levels may increase the risk of osteoporosis, sexual dysfunction, fatigue, cardiovascular disease, and mood disturbances .
Hypogonadism associated with acute and chronic illness and can also occur as a result of the illness itself or its treatment. Some of the systemic illnesses associated with hypogonadism include burn injury, stroke, cancer, HIV disease, myocardial infarction, diabetes, obesity, surgical stress, and others .
