Andropause is most commonly characterized by a subtle and gradual onset and very slow progression of symptoms associated with "low t" or low testosterone.
Often these changes are attributed to the natural and unavoidable consequences of aging. However, not all men show andropause symptoms as they age and not all men show a significant decrease in androgens as they age.
Five percent of males aged 40-50 years and as many as 70% of males over 70 years are confronted with “hypogonadism.”
Low testosterone levels have been associated with a decline in libido, erectile dysfunction, lack of energy, less physical strength and endurance, loss of height, decreased enjoyment in life, low mood, feeling grumpy, falling asleep after dinner, and decreased work performance.
