4 prune benefits for sexual health: what the research says

Search interest in “prunes benefits sexually” is real, but direct evidence is lacking. No human studies have tested prunes directly for sexual performance, libido, or fertility.

Still, this dried fruit does contain antioxidants, potassium, magnesium, fiber, and folate, which may support systems involved in sexual function.

Here’s what the research actually says.

Prunes aren't a sex superfood, and no human studies show they directly improve sexual performance, libido, or fertility. However, their general nutrient profile may support the systems involved in sexual function.

Here's a quick summary of the main prune benefits:

1. Erectile function: Prunes' polyphenols and potassium may support healthy blood flow throughout the body. But prunes aren't a treatment for erectile dysfunction (ED).

2. Sperm quality: The polyphenols in prunes, like chlorogenic acid, may play a role in reducing oxidative stress, which may play a role in protecting sperm health. 

3. Testosterone: Prunes contain boron, a mineral that some early research has linked to testosterone levels. They also have small amounts of magnesium, but not enough to make a big difference on its own. 

4. Mood and arousal: Prunes also contain folate, which impacts the production of neurotransmitters that regulate mood. Low folate can contribute to depression, which can affect libido and sexual function. That said, prunes aren’t the richest source of folate. Foods like leafy greens, lentils, and asparagus contain a lot more.

Get started

Prunes don't directly help with ED. But their nutrient profile may support the systems that matter for healthy erections.

Erections rely on healthy blood flow and a molecule called nitric oxide (NO), which helps blood vessels relax and widen. Conditions that interfere with circulation, like high blood pressure or diabetes, are some common causes of ED.

Prunes contain polyphenol antioxidants, especially compounds called chlorogenic acids. In lab and animal research, these compounds help reduce oxidative stress and inflammation — both of which matter for cardiovascular health. Some human studies have also found that daily prune consumption can improve antioxidant capacity and reduce markers of inflammation.

Prunes also provide potassium, which helps with blood pressure regulation. High blood pressure is a well-established risk factor for ED.

So while prunes aren't a treatment for ED, eating them as part of a varied diet may support the vascular systems that keep erections working normally.

There's no evidence that eating prunes raises testosterone in healthy people. Prunes are one of the richest food sources of boron, a trace mineral that early research has linked to hormone levels.

A small study in healthy men found that boron supplementation increased free testosterone after one week, though not all studies have successfully reproduced these results.  

Prunes also contain small amounts of magnesium, which is involved in testosterone production.

A study of nearly 400 people aged 65 and older found that higher magnesium levels were strongly and independently associated with higher total testosterone. But this was an observational finding and doesn’t mean that eating more magnesium raises testosterone. 

A serving of 4–5 prunes a day (about 40 grams) provides roughly 16 mg of magnesium, a small fraction of the recommended daily intake of 310–420 mg for adults. Foods like nuts, seeds, and leafy greens are far more concentrated sources of magnesium.

There's no direct evidence that eating prunes improves sperm quality. Prunes contain antioxidants that can play a role in protecting sperm from oxidative damage, though additional research is needed to confirm these results. 

Oxidative stress is a known factor in reduced sperm quality. When the body produces too many free radicals, it can damage sperm DNA and cell membranes, which affects motility and the ability to fertilize an egg.

Some reviews have found that antioxidant supplements may improve sperm parameters, including concentration and motility, in men with fertility issues. However, this hasn’t been replicated in all studies. 

No human trials have tested prunes specifically for sperm outcomes, so any benefit is extrapolated from broader antioxidant research.

If you're looking for ways to support sperm health and improve fertility, diet is one piece of a much bigger picture that also includes exercise, managing stress, avoiding smoking and excess alcohol, and other lifestyle changes.

There's no direct evidence that prunes affect mood or arousal. But they contain folate, which plays a role in producing the neurotransmitters that regulate mood.

That said, prunes contain only small amounts of folate. Other foods, such as leafy greens and lentils, are considered much richer sources of the nutrient. 

Folate is involved in serotonin, dopamine, and norepinephrine synthesis, all of which affect mood and motivation. Low folate has been linked to depression, and depression can impact libido and sexual function.

Some early research has also found that low folate levels are associated with ED, with folate dropping as ED severity increases. However, more research is needed.

Prunes contain several nutrients relevant to the systems involved in sexual function. Here's a breakdown based on data for 100 grams of uncooked prunes (about 10 prunes at roughly 9.5 grams

each).

Polyphenol antioxidants

Polyphenols are plant compounds with strong antioxidant properties. In animal research, dietary polyphenol intake may be linked to improvements in reproductive markers, including sperm cells, hormones, and testicular tissue, by reducing the production of reactive oxygen species.

Since prunes contain these antioxidants, it might be worth including them in your diet.

Potassium

One-hundred grams of prunes provides about 732 mg of potassium. Research has found that higher potassium intake is associated with a 35% lower risk of ED. And a review of clinical trials found that higher potassium intake can lower blood pressure in people with hypertension.

Boron

Prunes are one of the richest food sources of boron. A serving of 100 grams fulfills the estimated daily requirement of 2–3 mg.

Boron is a trace mineral that may play a role in hormone metabolism. One small study found that boron supplementation increased free testosterone and decreased estradiol, a female sex hormone that, in excess, is linked to sexual dysfunction in men. But these results have not been consistently replicated, and further research is needed.

Because the evidence is still early and mixed, prunes can’t be truly considered a testosterone booster. Nonetheless, their boron content is significantly higher than that of other foods.  

Folate

Prunes contain a small amount of folate (about 4 mcg per 100 grams). Folate is involved in mood-regulating neurotransmitters, and low folate has been associated with both depression and ED severity.

While prunes alone aren't a meaningful folate source, they do fit into a broader diet that supports it.

Fiber

With about 7 grams per 100 grams, prunes are a great source of dietary fiber. Diets rich in fiber have been associated with reduced risk of cardiovascular disease.

Fiber helps by lowering blood pressure and improving cholesterol, which also supports the circulation involved in sexual function.

Prune juice is made by processing dried prunes. But it's filtered before bottling, which removes most or all of the fiber. Whole prunes contain about 7 grams of dietary fiber per 100 grams, while prune juice essentially has no fiber after filtration.

Fiber is one of the key benefits of eating prunes. Higher dietary fiber intake has been linked to a lower risk of cardiovascular disease, including heart disease and stroke, and type 2 diabetes. But by removing most (if not all) of the dietary fiber, the juicing process rids prune juice of one of the key nutritional advantages of eating whole prunes. 

There's no evidence that prune juice is better than whole prunes for sexual health specifically. If you're choosing between the two, whole prunes are likely the better option because they deliver more fiber and fewer concentrated sugars per serving.

Prunes are easy to work into everyday meals and snacks. Here are a few simple ways to enjoy them:

• Eat them straight from the bag as a quick snack

• Chop them into oatmeal, yogurt, or granola

• Blend them into smoothies for natural sweetness

• Add them to trail mix with nuts and seeds

• Stir them into grain bowls or salads

• Stew them with cinnamon for a warm topping

If you prefer prune juice, start with a small glass. A little goes a long way.

Prunes are generally safe to eat, but there are a few things to keep in mind:

• Digestive effects: Prunes are high in fiber and sorbitol. This is why prunes may be a gentle laxative, but eating too many can cause gas, bloating, or loose stools.

• Calorie and sugar density: Prunes are a good source of energy in the form of simple sugars, so portion size matters. The fiber, fructose, and sorbitol content means prunes don't cause a rapid rise in blood sugar, but the calories and sugar still add up if you eat too many at once.

• Reasonable serving: You might find that a few prunes a day is enough to get the nutritional benefits without digestive issues.

Prunes are one part of a much broader dietary picture. A few other foods have stronger evidence for supporting the systems involved in sexual function:

• Leafy greens and beetroot are high in dietary nitrates, which the body converts into nitric oxide. Better blood flow leads to better erections.

• Fatty fish is rich in omega-3 fatty acids, which have antioxidant properties and may help support fertility and sexual function, based on animal research and early human studies.

• Watermelon is one of the richest natural sources of L-citrulline, an amino acid the body converts into nitric oxide. L-citrulline may help support erectile firmness in men with mild ED. Watermelon has also been linked to improved function of blood vessels, which is important for ED.  

• Dark chocolate contains cocoa flavonols, which have been shown to improve blood vessel function and nitric oxide production — both of which matter for erections. While a large study linked higher flavonoid intake overall to reduced ED risk, the strongest associations were tied to flavonoids commonly found in fruit. Still, dark chocolate has benefits for blood vessels, which could be helpful for men’s sexual health and function.

• Kiwi is a good source of vitamin C and potassium, and a small study found that eating kiwi before bed may help with sleep quality.

None of these foods is a replacement for medical treatment. But a diet that includes a mix of them, along with prunes, can support the systems involved in sexual function.

If you're dealing with ongoing ED, dietary changes alone are rarely enough. A diet with fruits like prunes may support these goals, but they work as a contributor, not a primary treatment.

ED has multiple causes, including vascular, hormonal, neurological, and psychological factors, and you should speak with a healthcare provider to find the best treatment for you. 

Prescription medications

These are the most common treatment options for ED. They work by improving blood flow to the penis when you are aroused and are generally very effective.

• Viagra (sildenafil): Most widely known option, usually taken about an hour before sex

• Cialis (tadalafil): Can last up to 36 hours and also comes in a daily low-dose version

• Ro Sparks*: A sublingual lozenge that dissolves under your tongue to deliver sildenafil and tadalafil for fast-acting and long-lasting effects 

• Daily Rise Gummies*: A once-a-day fruit-flavored gummy with tadalafil to help with sexual spontaneity

*These formulations are not approved by the US Food and Drug Administration (FDA), but their active ingredients have been individually FDA-approved for ED.

Lifestyle approaches

Simple habits can make a difference in your sexual health and function. These include:

• Regularly exercising

• Eating a balanced diet

• Cutting back on excess alcohol

• Quitting smoking 

Talk to your healthcare provider

If ED is affecting your sex life, it's best to talk with a healthcare provider. They may recommend checking for and addressing conditions like high blood pressure or diabetes if they're present.

This often improves erectile function, since ED is frequently an early sign of vascular issues.

Prunes are a nutrient-dense fruit that can fit well into a balanced diet, but their sexual health benefits are indirect at best. Here's what the research supports about prunes and sexual health: 

• Prunes do not directly treat ED. Prunes' nutritional profile may support the systems involved in sexual health, but no studies show prunes prevent or treat ED.

• The dried fruit won’t directly raise testosterone or improve sperm. Prunes contain boron and antioxidants that may play a role in hormone and sperm health. However, no studies have tested prunes specifically for these outcomes.

• Prunes can support cardiovascular health. The polyphenols and potassium in prunes may support circulation, which is important for sexual function, especially for people managing high blood pressure.

• They’re easy to include in your diet. A modest daily portion may be enough to get nutritional benefits without digestive issues.

If you're concerned about sexual health or ED, speaking with a healthcare provider (such as one on Ro) is the most direct path to evidence-based care.
