Men who ate about two handfuls of mixed almonds, hazelnuts and walnuts daily for 14 weeks improved their sperm count and had more viable "swimmers", scientists found.
The study comes amid a decline in sperm counts across the Western world, linked to pollution, smoking and diet.
Researchers said there was growing evidence a healthy diet could boost the odds of conceiving.
The scientists randomly divided 119 healthy men between the ages of 18 and 35 into two groups:
All of these are the parameters the World Health Organization lists as measurements of sperm quality and are associated with male fertility.
Experts said the study backed up others that showed a diet rich in omega-3 fatty acids, antioxidants and the B vitamin folate improved fertility.

Researchers said there was growing evidence a healthy diet could boost the odds of conceiving.
The scientists randomly divided 119 healthy men between the ages of 18 and 35 into two groups:
- One added 60 grams (2oz) of nuts a day to their normal diet
- One made no changes to what they ate

- count by 14%
- vitality by 4%
- motility (movement) by 6%
- morphology (shape and size) by 1%
