Hypogonadism is a clinical condition depicted by low androgen levels and associated with low muscle mass and strength, decreased ratio of lean body mass to adipose tissue, osteoporosis, decreased libido, decreased hematocrit, impaired cognition, and mood disorders. It has been well established that aging is associated with decreased testosterone levels in males, and by 80 years of age, 40% of men have serum testosterone levels within the hypogonadal range. Hypogonadism in aging males is often called andropause or androgen deficiency of the aging male (ADAM).
