Men who consume about two handfuls of mixed almonds, hazelnuts and nuts every day for 14 weeks improved their sperm count, and had more viable “swimmers”, according to a study by scientists .
The study comes as the number of sperm decreases in the Western world. A fact linked to pollution, smoking and food.
The researchers report that there is growing evidence that a healthy diet could increase the chances of conceiving.
About one in seven couples have difficulty having a child and about 40-50% of infertility cases are attributable to men.
Scientists randomly assigned 119 healthy men aged 18 and 35 in two groups:
We added 60 grams (2oz) of nuts a day to their normal diet
We made no change to what they ate
Those in the nut group improved the sperm:
- 4% vitality
- motility (movement) of 6%
- morphology (shape and size) of 1%
All these findings are parameters that the World Health Organization indicates as being measures of sperm quality and are associated with male fertility.
Experts argue that nuts are rich in omega-3 fatty acids, antioxidants and vitamin B folate that improves fertility.
