Based on total testosterone (TT) concentration, the prevalence of hypogonadism in men reporting to primary care offices was estimated to be 38.7%. The medical conditions that occurred significantly more frequently among hypogonadal men than eugonadal men included increased BMI, hypertension, hyperlipidaemia, diabetes, and asthma or COPD. As men age, they are susceptible to conditions that share many of
the same symptoms similar to hypogonadism. The presence
of these conditions may, in effect, mask underlying hypogonadism and negatively impact quality of life.
