Dehydration And Erectile Dysfunction

An optimal sexual response in males is dependent on every aspect of their body’s system that is associated with sexual functioning. In males, arousal triggers a sexual response in the form of erections. Many individuals might fail to get erections, which could be attributable to many factors. The factors that contribute to erectile dysfunction may differ from one individual to another.  

For a healthy erectile response, there must be a proper flow of blood to the reproductive organs. If the blood volume is low in your body. Then it might give rise to erection troubles. The reason for low blood volume can be dehydration, which causes the reduction of fluids in the body.   

What is dehydration?  

A condition like dehydration occurs when an individual loses more fluids than they consume. In general, the human body is made up of about 60 to 70% water. The brain and heart are composed of 70% water. Those with adequate levels of fluids in their bodies have balanced chemicals and minerals. Which are necessary for optimal brain function through neurotransmitter operation. A well-hydrated individual also has a healthy digestive system, an adequate supply of oxygen throughout the body, support to bones through cushioning, healthy joints, healthy salivary gland function, and a normal body temperature. 


Water helps you in getting rid of toxins. Also, it prevents your body from overheating after a workout session. It brings back the normal body temperature and helps in restoring the minerals and electrolytes that were lost due to sweating. Its symptoms include dryness of mouth, dry coughs, headaches, fatigue, confusion, weakness, lightheadedness, low blood pressure, muscle cramps, constipation, darker urine, and skin flushing.

Factors causing dehydration

When you do not consume adequate water, it can lead to dehydration. Individuals may experience this, especially during summers, as the hot weather makes them sweat to keep the body cool, but when the body loses water while sweating, it is also losing electrolytes. In addition, those who exercise tend to lose too much water through sweating. So, to bring back those electrolytes, one must stay hydrated regardless of what season it is. Moreover, it is necessary to consume foods that are rich in water, such as leafy greens, cucumbers, fruits like watermelon, apples, etc., and vegetables. 

How dehydration affects erection function

  • Reduction in the blood volume

When arousal happens, the cavernous nerves present in the penile trigger the release of a neurotransmitter, known as nitric oxide in the blood vessels. This neurotransmitter causes more blood to flow to the penile shaft, which leads to erections. Blood flow is necessary for an erection to occur, however, individuals suffering from dehydration might not be able to perform well sexually.

This happens as the lack of sufficient hydration in the body reduces the blood volume, and as blood flow is fundamental to erection function, lack of enough blood volume can affect the erection response and lead to erectile dysfunction. This can be a temporary problem, which can be restored when the blood volume increases post-hydration.

  • Negative impact on blood flow due to low blood pressure

Dehydration can hinder the flow of blood in the body and deprive the organs of adequate hydration. This can adversely impact your mood too. It is quite obvious that low blood volume causes the blood to flow through the vascular system at a slow speed and pressure.

For a healthy erection function, there must occur a surge of blood to the penile shaft after arousal, but since the blood pressure is low owing to dehydration, the blood flow to the penile does not happen adequately. Therefore, it is necessary to maintain adequate hydration levels in the body otherwise the lack of sufficient water in the body can have a negative impact on an individual’s overall well-being.   

  • Vascular dysfunction

Lack of fluids in the body causes the constriction and narrowing of the blood vessels due to the low amounts of blood. This poor hydration contributes to the impairment of the flow of blood to all organs and parts of the body, including the penile shaft. This can lead to impotence problems. Hence, it is imperative to keep yourself hydrated by drinking around 6 to 8 glasses of water a day.         


If an individual is severely dehydrated, then it might take them a bit longer to get their sexual function restored optimally. As they start taking care of themselves and consume enough liquids in a day, they will be able to increase their blood volume and bring back their blood pressure to normal range. Although, one can use ED drugs like Malegra, for treating their impotence issues. These drugs are made using sildenafil. Which is the same component that is present in the FDA-approved ED medications known as Viagra. The medication may work in the presence of arousal.

In conclusion

Dehydration does contribute to sexual difficulties by giving rise to temporary difficulties in getting erections. Hydration is of utter importance when it comes to sexual health. After all, the erection function is dependent on the neurotransmitter response and blood circulation to the reproductive organs. Which occurs only when the body is adequately hydrated.
