Walnuts, almonds and hazelnuts are tested for erectile and sexual function, sperm count and sperm quality.
In 2013, I published a video based on a study that found that men with erectile dysfunction who ate 100 grams of pistachios (a little more than three handfuls) a day for three weeks had “significantly improved erectile function.” It’s always nice to see a whole food intervention have clinical impact, and I was interested to revisit the topic and see what has been published since then.
Even if you ignore all the lab animal studies on hazelnuts is improved Rat sperm function – in fact, there’s a study that says “Hazelnut consumption improves testicular antioxidant function and sperm quality in young and old rats” – you never know what you’ll find when you search the medical literature for nuts and sexual function. I found “a case of penis strangulation with a metal hex nut” in which someone inserted it into his penis “for sexual pleasure” but could not remove it. (I suspect that certain types of nuts can sometimes make things worse.) They tried the Dundee technique, which involves 20 holes to relieve pressure, but that didn’t work, so they tried diamond disc cutting. It slipped several times, but the nut was successfully removed. All’s well that ends well.
This made me curious. Obviously, the penis skirt is as popular as it gets is the entire scoring system that emergency physicians can use, as you can see here and at 1:21 in my video Mixed nuts are being tested for erectile dysfunction. If there is no exercise, surgeons advised“you can use a hammer and chisel to remove the nut.”
Exercise? Oh, them meaning dental drilling. Doctors describing one case boasted about “sharply cut edges,” but to me it seems too thick. You can see for yourself below and at 1:38 in mine video.
to “hold up penis from fatal consequences” (that’s a strange way to say it), urologists should be aware of all available tools and approaches, and if you don’t. know How to handle the saw, you can always go to the local blacksmith, but only if “special consent is obtained from the patient”!
But how do you go? remove Iron rod or steel head? “With a heavy air grinder provided by the fire department,” requires six hours of cutting and fire jackets to protect the patient from sparks. Use whatever you need – a saw, a “cement eater”. You can even to use the silk twisting method proposed by Dong et al.
Back to the task at hand! Consumer “At least one serving of vegetables per day and more than two servings of nuts per week were associated with a greater than 50% reduced risk of ED” (erectile dysfunction) in one short-term study. But such observational studies cannot prove cause and effect. It is like that to find that men who eat healthier have better sperm motility. Maybe the men who eat nuts are just health nuts and the improvement is due to other factors like exercise. What we need is an interventional trial.
And there is one: a randomized controlled trial learned “Effects of Nut Consumption on Sperm Quality and Function”. Healthy men were fed a standard American diet with a mixture of walnuts (30 grams) and half a handful (15 grams) each of almonds and walnuts. Individuals in the walnut group experienced significant improvements in total sperm count, vitality, motility, and shape, perhaps because “the walnut group showed a significant reduction in SDF”—sperm DNA fragments. Nuts have been found to protect the DNA of their sperm. It’s too bad the researchers didn’t measure erectile dysfunction and men’s sexuality while they were at it. Oh, but they did!
what is effects of nut consumption on erectile and sexual function from the same study? Researchers report that those in the walnut group saw significant increases in orgasmic function and sexual desire, but what about erectile function? Any time you see this kind of glass-half-full selective reporting, you suspect some kind of industry funding, and indeed that was the case here; The research was funded in part by the International Nut and Dried Fruit Council. Yes, there was a small increase in orgasmic function and sexual desire of questionable clinical significance, but no improvement in erectile function, sexual satisfaction, or overall satisfaction. As with so many comparisons, even the so-called significant findings may not even be statistically significant.
But why did the pistachios I mentioned in 2013 work, while these other nuts didn’t? Well, that was the original study was completed in men aged 40-50 who already had chronic erectile dysfunction for at least a year, while the average age of the participants in the new study was 24. So individuals in later studies may have started with maximum rotation and not left much room for the nuts to work their magic.

Sorry for that crazy tangent! I just wanted to give people a taste of what it’s like when you dive into the medical literature.
The 2013 video I mentioned Pistachios for erectile dysfunction.
How about nuts for arterial circulation? see Nuts and arterial function.
