Eating 60g of walnuts, hazelnuts and almonds each day may increase sexual desire in men and give them better orgasms.
Spanish researchers claim men reported having a better sex life with the addition of two large handfuls of nuts a day.
Scientists believe the nutrients in the nuts help transmit signals to the penis which boost sensitivity and performance.
Antioxidants – abundant in nuts – also benefit the cardiovascular system, and healthy blood circulation is linked to an increased libido.
However, the researchers said these are merely speculations and the real reasons behind the link need to be investigated.
The Universitat Rovira i Virgili and the Pere Virgili Health Research Institute in Spain conducted the 14-week trial.
They divided 83 healthy men aged 18-35, with no history of erectile dysfunction, into two groups.
