8 Common Symptoms of Low Testosterone in Men
Marshall Medical Group • May 19, 2025
Here are 10 common symptoms of low testosterone (low T) in men, which can significantly impact both physical and mental health:
1. Low Sex Drive (Libido)
- One of the most noticeable signs; men may lose interest in sex or have reduced sexual thoughts and fantasies.
2. Erectile Dysfunction
- Difficulty getting or maintaining an erection, especially morning erections, may signal low testosterone levels.
3. Fatigue and Low Energy
- Persistent tiredness and lack of motivation despite rest can be related to hormonal imbalances.
4. Loss of Muscle Mass and Strength
- Testosterone plays a key role in building and maintaining muscle; men may notice
weaker muscles or
slower recovery from workouts.
5. Increased Body Fat
- Especially in the abdominal area or development of gynecomastia (enlarged breast tissue).
6. Mood Changes
- Symptoms may include irritability, depression, anxiety, or difficulty concentrating ("brain fog").
7. Decreased Bone Density
- Over time, low T can lead to osteopenia or osteoporosis, increasing fracture risk.
- Thinning of beard growth, chest hair, or overall body hair may occur gradually.
8. Poor Sleep or Insomnia
- Some men with low T experience trouble falling asleep or restless sleep, which can worsen fatigue and mood issues.
