Low testosterone can show up gradually, which is why many men blame age, work stress or poor sleep before getting tested. The Canadian Urological Association describes testosterone deficiency as a condition that should be assessed using both symptoms and blood work, not symptoms or lab numbers alone.
Common signs may include:
- Low Libido: Less interest in sex or fewer spontaneous sexual thoughts.
- ED: Difficulty getting or maintaining erections.
- Low Energy: Fatigue that does not improve with better rest.
- Brain Fog: Trouble focusing, remembering or staying mentally sharp.
- Mood Changes: Irritability, lower motivation or depressed mood.
- Body Changes: Increased body fat, reduced strength or loss of muscle mass.
A large primary care study found hypogonadism in 38.7% of men aged 45 and older who presented to primary care offices, which supports why persistent symptoms should not be ignored.
