- Causes Starting at about age 40, men's testosterone levels
drop by about 10% every decade.1 At the same time, another
factor in the body called Sex Binding Hormone Globulin, or
SHBG, gradually increases. SHBG traps much of the testosterone
that is still circulating and makes it unavailable to the
body's tissues. What's left over tries to carry on the
beneficial work of testosterone and is known as
- Andropause is associated with low 'bio-available'
testosterone levels. Every man experiences a decline of
bio-available testosterone, but some men's levels dip lower
than others. And when this happens these men can experience
symptoms of Andropause.
- These symptoms can impact their quality of life and may
expose them to other, longer-term risks of low testosterone.
It is estimated that 30% of men in their 50s will have
testosterone levels low enough to be causing symptoms or to
put them at risk.
