More Coffee, No Erectile Dysfunction?

What is Erectile Dysfunction?

In the United States of America, about 18 million males over the age of 20 are diagnosed with erectile dysfunction. When it comes to middle-aged men the number of individuals diagnosed is way higher.

44 per cent of all males over the age of 40 suffer from erectile dysfunction and it gets worse for the senior citizen category. 70% of all the males above 70 years of age in America are a patient of this illness.

A penis erects in response to sexual arousal, which is caused due to the development of sexual thoughts or physical stimulation in males. An immense amount of arteries present in the human body transfer a rush of blood to the penis, for an erection to take place.

This rush of blood flows into the penis, causing it to harden and erect fully; in contrast to the relaxed state that it was in previously. Erections in males start during the onset of adolescence and are an essential aspect of reproduction.

This biological phenomenon becomes weak or in some males, becomes absent as they get older. When this starts to happen, the individual is said to be suffering from erectile dysfunction.

Erectile dysfunction can be easily identified as it is caused due to the lack of force in the blood movement into the penis, post-sexual arousal which restricts the penis to erect fully


Based on a study conducted by PLUS ONE, research has suggested that coffee does have a hand in curing or in helping individuals to ward off symptoms of erectile dysfunction. The study was authored by David S. Lopez.

The discussions and the conclusion of the study are present at the end of the article. Some people with hypertension, high blood pressure or even obesity warded off the symptoms with the constant consumption of coffee. Other than obesity, many of these diseases have been taken care of by tablets such as sildenafil citrate.

Will your erectile dysfunction be treated if you stop drinking coffee?

 However, a certain section of the sample population was not helped by the consumption of coffee and these were the individuals with a pre-existing condition of diabetes.  Caffeine did not show the same protective features which it did for people affected by the aforementioned conditions, and some say that it is because of the fact that diabetes in itself comes with its own set of vascular issues.

the author, David S Lopez said “As diabetes is one of the strongest risk factors of erectile dysfunction, this wasn’t very surprising for me and my team” The studies haven’t yet been able to tell us if men who don’t drink coffee currently should start.

Researchers aren’t sure if new coffee drinkers will also get the same protective features that regular coffee drinkers get, especially in the context of saving them from erectile dysfunction.  However irrespective of whether coffee can help individuals who never drink coffee, it has various other health benefits. These benefits may have some kind of a link to solving the causes or symptoms of erectile dysfunction.

Some of these benefits are: 

  • It helps in burning fat: Caffeine is reported to be one of the few natural substances that have been proven to aid fat burning. The metabolic rate of individuals drinking coffee regularly has witnessed a significant increase up to 11 per cent.  It is also easily accessible in comparison to their natural substitutes.

Obese individuals have witnessed up to 10 per cent decrease in their overall weight and lean people have seen a 29 per cent decrease. One of the main causes of erectile dysfunction is obesity. Obese individuals have a lot of fat which ends up blocking major arteries in the body. Weight loss can help these individuals regain sexual pleasure and drinking coffee is the best way to do so.

  • Increases Energy Levels: The active ingredient of coffee is caffeine. It has been identified by scientists as the most commonly consumed psychoactive substance. Coffee has helped individuals all around the world to help feel less tired and subsequently increase their energy levels.

Caffeine is an excellent stimulant which is absorbed by your bloodstream. After you drink your cup of coffee, the caffeine is absorbed by the bloodstream, which transfers it into the brain.

When the caffeine reaches the brain, it blocks the inhibitory neurotransmitter adenosine. Adenosine is the reason why you feel drowsy and eventually fall sleep. Neurons are fired due to the release of dopamine norepinephrine which energises the entire body.

This increase in energy helps the individual to have sexual intercourse. Depression also leads to erectile dysfunction, if dopamine is produced then individuals start to feel happy, which helps them get an erection and in the mood for sex.

  • Lowers the risk of getting Parkinson’s disease: In simple terms, Parkinson’s is caused due to the absence of dopamine-producing neurons. Parkinson’s does not have a cure which makes coffee a bigger asset in helping men and women avoid it.

Studies have shown that regular coffee drinkers are at much lesser risk in comparison to non-coffee drinkers, the risk is reduced by up to 60 per cent in some lucky individuals. Parkinson’s is another reason for erectile dysfunction. Once the neurotransmitters stop firing the way they should, erectile dysfunction is soon to follow.

The patients slowly start to lose motor controls due to Parkinson’s and hence physically restricting them from having sexual intercourse. A study was conducted that caffeine was the only reason that Parkinson’s was prevented and no other ingredients. Individuals who had decaf did not see the same benefits from coffee which the caffeinated coffee drinkers did.

Research is trying to get better every day but scientists have not been able to say for sure if non-coffee drinkers should start drinking to protect themselves from erectile dysfunction. As previously mentioned, coffee does come with its numerous health benefits, but it might not be easy for some people to start consuming.

One of the main reasons as to why scientists don’t want to encourage the consumption of coffee openly is because it is addictive.  Individuals who have never had coffee before tend to get hooked onto it very quickly. It is safe to ask your doctor first before starting your new coffee drinking habit. This study, however, benefits the current coffee enthusiasts, as they can start feeling better with each cup that they consume

Why would caffeine prevent erectile dysfunction?

The authors of various research papers found that the main function of caffeine was to positively affect blood vessel function. Improving the blood vessel function is how it perfectly helps individuals from being diagnosed with erectile dysfunction.

 The mechanics by which all this is possible is not so hard to understand. Caffeine has been seen to trigger a series of pharmacological effects which lead to the relaxation of the penile helicine arteries and the cavernous smooth muscle that lines the cavernosal spaces which henceforth ensures an increase in the penile blood flow.

What are all these parts of a penis? The helicine arteries of the penis are all the arteries which surround the penis and are mainly responsible in the process of getting a successful erection. The two corpora cavernosa are sponge-like tissues that contain trabeculae, irregular blood-filled spaces which are lined by endothelium and separated by a connective tissue called the septa.

The cavernosa lie along the penis shaft and go all the way to the head of the penis from the pubic bones. Furthermore, the area through which the blood flows and hardens the penis is kept clear by the help of the substances produced by the caffeine.  

Key aspects of the study conducted by PLOS One: 

Role of Caffeine Intake on Erectile Dysfunction in US Men, 2004

The discussion and conclusion of the team of researchers from Plus one is listed below which gives us an ideal viewpoint, of the effects of caffeine on erectile dysfunction

A test was conducted in the form of a questionnaire which was given to 3700 men. In which they had to fill out their everyday diet. They also had to specify if they have erectile dysfunction or not. The tests had found out that caffeine intake was indeed associated with a reduced likelihood of erectile dysfunction.

The team of researchers then ran the data through various analysis algorithms and cross-checked the results of the sample results with each other. It was found that individuals who drank 85-70 mg of coffee per day were 42% less likely to have dealt with erectile dysfunction.

The next category in the sample audience were men who drank 171 to 303 mg of caffeine in a day. These men were 39 per cent less likely to have dealt with this disorder. The aforementioned two amounts are the most common consumption patterns in today’s busy lifestyle.

The reason why this was groundbreaking was because the two previous studies based on the same premise did not test positively. Those researchers were not able to find a possible link between coffee and erectile dysfunction. This was mainly because the previous studies had a much smaller group size.

The study also used a registered dietary recall period, which is a method that has been developed and validated by the US Department of Agriculture to report population-based estimates of daily caffeine intake.

However, the authors of this study tell us that this isn’t perfect. The reason why they say that is similar to why doctors aren’t sure about suggesting their patients start drinking coffee rather than having a sildenafil tablet to help with the erectile dysfunction; the causes of the disorder can vary.

Multiple risk factors of erectile dysfunction have not been addressed, the main cause being cardiovascular diseases. Surveys have also been identified as having an inherent bias.
