Impact of testosterone deficiency
How common is testosterone deficiency?
Testosterone deficiency is common, however the exact proportion of men that are affected is unknown and the condition is expected to be underreported.
It is estimated that 40% of men over the age of 40 are deficient and 50% of men over the age of 80 are deficient. 
What impact does testosterone deficiency have?
Testosterone is an integral hormone in the maintenance of overall health and wellbeing as well as being the key androgen in the maintenance of male sexual characteristics.  Expectedly, deficiency causes a significant impact to the mental, emotional and physiological health of those affected.
Deficiency impacts many aspects of overall health so it is important for men to recognise the signs and symptoms of deficiency and speak to their doctor if they expect they may have the condition.
