Testosterone Deficiency Syndrome and ED

Testosterone Deficiency Syndrome (TDS) happens either when the testicles don’t produce enough testosterone, or when hormones are out of balance, causing a low testosterone level (usually below 12 nmol/L) ^{25, 50}. Late-onset hypogonadism (LOH) is a form of TDS associated with advancing age ⁵⁰.

Low testosterone can cause a range of symptoms, including ED, loss of sexual desire (libido) and a general lack of energy, as well as depression, hair and muscle loss and a potentially increased risk of developing osteoporosis ^{36, 1, 11}.

It is thought that one in every 200 men ¹⁹ in the general population have TDS. However TDS is sometimes undetected as the symptoms are quite general and usually put down to ‘getting older’. Find out more about TDS.
