Hormone therapy for men is typically centered on testerone levels.
Testosterone is the dominant hormone in men, and levels tend to peak in the late teen years. Once men reach the age of 35 their testosterone levels may begin to decline at a rate of 1-3% each year. But age is not the only thing that contributes to this drop in hormones: weight and lifestyle changes, genetics, and autoimmune disorders can also plummet testosterone levels.
Low testosterone levels activate symptoms that may negate quality of life.
