Certain fruits help reduce male infertility. Although the news seems surprising, it is nevertheless a very serious study carried out by Australia’s Monarsh University. Their work was published in the journal Advances in Nutrition on November 17, 2023.

Some of the men (223 of them exactly) had to ingest 60 to 75 g of nuts or nut supplements daily (30g of walnuts, 15g of almonds, 15g of hazelnuts) for 12 weeks.
The control group, for its part, followed a nut-free diet.
Different judgment criteria were also taken into account, such as sperm concentration, their vitality, motility and morphology.
Result ? Men whose diet included 60 g of nuts per day had better sperm quality (at almost all levels: motility, vitality and morphology) than those who did not consume them.
On the other hand, the fruit had no impact on sperm concentration.
“Our meta-analysis shows that including at least 2 servings of nuts per day as part of a Western-style diet in healthy men improves sperm parameters, which are predictors of fertility masculine. Due to their nutritional profile, these fruits have been found to have the potential to promote positive reproductive outcomes“, conclude the researchers.
