The advent of Viagra and other erectile dysfunction (ED) treatments revolutionized the world of sexual medicine. No longer did men with certain medical conditions or age-related ED have to resign themselves to unsatisfying sex lives.
However, ED drugs do not work for every man. Some men experience side effects, while the drug is unsuitable for others, such as men with certain types of chest pain and heart disease.
For men who cannot take Viagra, watermelon is a safe alternative that is unlikely to cause serious side effects.
Why watermelon could help with ED
Watermelon is a natural source of citrulline. Citrulline is an amino acid that may support better erections.
Viagra works by increasing blood flow to the penis, allowing a man to more easily get an erection when he is aroused. Citrulline may do the same thing, although it works in a different way to Viagra.
Preliminary research suggests that the body may convert citrulline to another amino acid, called arginine. Arginine converts to nitric oxide. Nitric oxide opens the blood vessels wider, increasing blood flow to the penis and improving erections.
Because watermelon is mostly water, the highest concentrations of citrulline come from concentrated watermelon juice.
Men who want to try watermelon as a natural Viagra may find better results with watermelon juice.
What the research says
Preliminary research is promising, and there are few or no risks associated with consuming watermelon. This means that most men can safely try watermelon juice or citrulline supplements as an alternative to Viagra.
A 2013 study gathered data on rats with ED due to low blood flow to the penis. This disorder, called arteriogenic erectile dysfunction, is a common cause of erectile problems in humans.
Rats that took a citrulline water supplement experienced improvements in erectile function compared with rats that received a placebo and rats that underwent surgery on their blood vessels. This finding suggests that citrulline may improve blood flow, potentially improving erections.
A 2014 study evaluated male rats treated with watermelon flesh extract. Rats who consumed watermelon were more likely to mount females and start intercourse. This increase in libido, the study’s authors concluded, suggests that watermelon might also be a viable treatment for ED.
There were no serious side effects, and the rats that ate watermelon extract did not experience an increase in weight.
Research published in 2017 sought to further understand the role of citrulline and arginine in erectile function. Researchers measured levels of both amino acids in 122 men with ED.
They found lower levels of one or both amino acids in men with ED, particularly in men with arteriogenic erectile dysfunction. This suggests that increasing levels of either citrulline or arginine, or both could improve erectile function.
Risks and benefits of watermelon for ED
Watermelon is considered safe, even in large quantities. Unless a man has an allergy to watermelon, he can safely consume it.
Men with diabetes should discuss with their doctors how much watermelon they can safely consume. Watermelon and other fruits can raise blood sugar levels; so eating large quantities may be unsafe for some people with diabetes.
Watermelon is low in calories, but overconsumption of any food can lead to weight gain. It is unwise to eat large quantities of any food, especially if doing so causes gut pain or uncomfortable feelings of fullness.
No research has found any serious side effects associated with watermelon in healthy men or animals.
How to use watermelon
The benefits of watermelon come from citrulline. Using watermelon in a way that maximizes citrulline intake can increase the benefits.
A 2005 study found that red watermelon was slightly lower in citrulline than yellow or orange varieties. Watermelon rind has higher concentrations of citrulline than the fruit’s flesh. There were no significant differences between seeded and seedless watermelon varieties.
To maximise citrulline intake, people can try blending watermelon rind in a smoothie.
Viagra is a safe, effective option for most men. For men who prefer to avoid drugs or who cannot use Viagra, watermelon is one of many possibilities.
Men should talk to a doctor to work out their best treatment option. Sometimes, a combination of natural and medical remedies can help.
