To know if testosterone is low, watch for these common signs and symptoms:
- Low sex drive or decreased libido
- Difficulty achieving or maintaining an erection (erectile dysfunction)
- Persistent fatigue despite adequate sleep
- Loss of muscle mass and strength, and increased body fat
- Mood changes such as depression, irritability, or anxiety
- Decrease in beard or body hair growth
- Shrinking testicles
- Hot flashes or night sweats
- Trouble concentrating or memory problems
If several of these symptoms are present, it could indicate low testosterone. The only definitive way to know is through a blood test measuring testosterone levels, ideally done in the morning. A healthcare provider can interpret the results in the context of symptoms to diagnose low testosterone and advise on treatment options such as testosterone replacement therapy if needed.
