I applaud Dr. Oz's answer on Oprah show regarding andropause or as we like to call it Man-o-pause! For men Testosterone reaches a peak at around age 25-30 and then goes down at a rate of 1-2% per year which is why as Dr. Oz points out that the onset of symptoms is very slow and not very obvious to men. The changes with menopause tends to happen over a shorter period of time so women are more aware of the changes. Men may notice a lack of energy, declining memory, increased moodiness, a decrease in libido and/or erections and a loss in muscle tone, increase in fat and a loss of stamina. Levels of testosterone are easily checked in a blood test and can be corrected with testosterone therapy. In addtion to improving all of the above symptoms, replacing testosterone also decreases the risk of heart disease and alzheimer's disease and can improve cholesterol and blood sugar levels among many other benefits. Many of the changes that men tend to chalk up to aging can be improved with testosterone therapy.
Insomnia in men resulting from low testosterone and sleep apnea can lead to several other problems including fatigue, reduced insulin sensitivity, low human growth hormone levels and high cortisol levels. Cortisol, the stress hormone, will increase with prolonged insomnia because of the stress on the body. Constant high levels of cortisol can create a hormone pattern that further reduces testosterone production. It can also lead to adrenal fatigue which often worsens the fatigue and insomnia.
