If this sounds like something straight out of your bedroom, you aren't alone: according to the Cleveland Clinic, 40 per cent of men are likely to experience some form of erectile dysfunction by age 40.
It's no secret that your diet and lifestyle play a huge role in your penis' performance – but scientists may have just discovered an erection-boosting food that stands out from the rest.
Researchers in Turkey monitored the lives of 17 men who had suffered erectile dysfunction for at least one year. The men were told to eat 100g of pistachio nuts everyday for three weeks. The results were astounding.
The study, published in the International Journal of Impotence Research, found that after gorging on nuts for 21 days, all of the men experienced stronger erections, higher libidos, increased sexual satisfaction and were more likely to orgasm during intercourse.
Apart from the sexual benefits, the men also had higher levels of HDL (good cholesterol) and lower levels of LDL (bad cholesterol).
Nutritionist Nigel Mitchell told the Daily Star that pistachios are sometimes considered "love nuts" as they contain all the nutrients essential for a successful sex life.
"Pistachio nuts are an ideal snack, they taste great and are a good source of vegetable protein, healthy fats and the green and purple pigments are antioxidants that help the body deal with damage and stress," Mitchell said.
If nuts aren't for you or you happen to be allergic, here are five other foods that prevent erectile dysfunction.
