Quick answer: Low testosterone can cause low desire, fatigue and loss of muscle, but these symptoms have many other causes. Diagnosis needs morning blood tests. Herbal "boosters" such as Tribulus rarely raise testosterone in trials.
Possible signs
- Low sex drive and fewer morning erections
- Tiredness and low mood
- Loss of muscle, more body fat
Other causes of the same symptoms
Poor sleep, sleep apnoea, depression, weight gain, alcohol and thyroid problems.
How testing works
Testosterone peaks in the morning, so doctors usually test early and repeat abnormal results.
About boosters
Most herbal testosterone boosters have not raised levels in controlled studies. Sleep, weight loss and strength training help more.
See maca, fenugreek and Tribulus.
