Short answer
Many men notice some change in desire after 40, but a sharp drop isn’t inevitable. Stress, sleep, weight, alcohol, health conditions and relationship routine usually play a bigger role than age alone.
Why this happens
- Gradual hormonal changes.
- Work stress and responsibilities.
- Health issues like diabetes or blood pressure.
- Routine and lack of novelty in the relationship.
What helps
- Look after sleep, exercise and alcohol intake.
- Get a health check.
- Bring novelty and play back into the relationship.
- Talk openly with your partner about changes.
When to see a doctor: low desire with tiredness, low mood or erection problems can signal low testosterone or other treatable conditions — see a doctor.
