Men and women who want males in their life to be a little more fertile by doing the bare minimum, boy, have we got some news for you.
Diets rich in nuts produce not only a higher sperm count, but also more fertile swimmers, according to a study from the Human Nutrition Unit of the Rovira i Virgili University in Spain.
That's right—cast away your worries and concerns as you reach for another handful of almonds to snack on.

Researchers gathered a group of healthy young men—aged between 18 and 35—and after 14 weeks, they discovered men who included 60g a day of mixed almonds, hazelnuts, and walnuts had both a higher sperm count as well as sperm of a higher quality.
But—and there's always a but—the results aren't conclusive yet.
Because the researchers split the men into a nut-eating group and a non-nut-eating group—providing the nut-eaters with their carefully measure portion of nuts each day—the experiment didn't reflect a normal, everyday diet.
Therefore, it might mean choosing a healthier replacement for a less nutritious snack could work just as well as nuts, or it may mean nuts are the answer to all of our infertile fears.
The researchers did admit that the nut findings "support a beneficial role for chronic nut consumption in sperm quality", so it's a definitely a step in the right direction.
Before you throw out all your other food and survive on nuts alone, make sure you've ticked all the boxes science knows for fact will improve your fertility. Avoid the ciggies, booze and drugs and make sure you maintain an all-round healthy lifestyle and keep a lid on your stress levels.
But, if you're a nut fiend, chowing down on some walnuts can't hurt.
