Kidney disease causes erectile dysfunction by disrupting several key systems that control sexual function. When the kidneys weaken, they can’t properly regulate hormones, blood pressure, and toxin removal, all of which are vital for erections. This leads to low testosterone, poor blood flow, and nerve damage. Toxin buildup and chronic fatigue further reduce energy and desire, while emotional stress adds to the problem. Together, these changes explain why almost 70% of men with chronic kidney disease experience some level of ED.
Erectile dysfunction (ED) is one of the most common yet overlooked complications of kidney disease.
Your kidneys do much more than just filter waste. They play a vital role in controlling blood pressure, keeping fluid levels balanced, producing red blood cells, and regulating important hormones. All of these functions are closely tied to healthy erections. When the kidneys don’t work properly, it throws these systems off balance, and that disruption can directly affect normal erectile function.
This article explains how kidney damage leads to ED, what factors make it worse, and how men can manage both sexual dysfunction and kidney health.

Yes, kidney problems can cause erectile dysfunction. Healthy erections rely on good blood flow, balanced hormones, healthy nerves, and a strong mind-body connection. Kidney disease interferes with all of these, as the kidneys are responsible for regulating most of these systems.
Studies on erectile dysfunction prevalence show that:
When the kidneys start to fail, they disrupt many of the systems that erections depend on, at once. Chronic Kidney Disease can cause:
Let’s look at each of these in detail.
Your kidneys are connected to your body’s endocrine system, which is a network of glands that secrete hormones. These hormones control everything, from growth to energy to sex drive. When kidney function declines, this hormonal balance is disrupted.
The hormones affected are:
Normally, the brain sends signals through luteinizing hormone (LH) to the testes, telling them to make testosterone, the male hormone that drives libido and erections.
In chronic kidney disease, this signaling system (the HPG axis) is disrupted, so the testes don’t respond properly, leading to testosterone deficiency. [3]
This hormone is usually associated with breast milk production in women and often rises in men with CKD. [4]
This hormone helps regulate calcium and bone health and can also rise in kidney disease. [5]
This hormone is deficient in kidney patients because the kidneys activate vitamin D. [6]
When this imbalance occurs, men develop what doctors call uremic hypogonadism. This is a fancy way of saying the testes aren’t producing enough sex hormones because the kidneys aren’t working properly.
For men, this means:
An erection mainly depends on good blood flow and healthy blood vessels.
Kidney disease can cause many problems:
Getting an erection also requires a steady stream of messages traveling from the brain to the penis. If the nerves that carry these messages are damaged, the signals don’t reach the penis properly. [1]
When your kidneys are healthy, they act like the body’s filter and constantly remove waste products and balance minerals. But in kidney disease, this system breaks down, resulting in a “toxic internal environment” that affects organs responsible for sexual function.
In chronic kidney disease (CKD), the toxins aren’t removed properly and start to build up in the blood, a condition called uremia.
These toxins:
Beyond waste buildup, kidney disease causes chemical disturbances in the body:
Kidney disease doesn’t just affect the body but also takes a huge toll on the mind and emotions. The psychological aspects of dealing with a chronic illness can cause ED.
Kidney disease on its own can cause erectile dysfunction, but most men with chronic kidney disease (CKD) also deal with other health conditions, medications, or treatments that make the problem even worse. This explains why ED is so common in men with kidney problems.
Many men living with chronic kidney disease (CKD) also face other long-term health problems, and these make erectile dysfunction even more likely. Some of these conditions are:
Drugs used for kidney and heart conditions often worsen ED:
For men with end-stage renal disease (ESRD), dialysis is often the only way to survive once the kidneys can no longer filter blood on their own. While dialysis saves lives by removing waste and balancing fluids, it doesn’t completely solve the sexual problems caused by kidney failure. In fact, many men notice that their erectile dysfunction (ED) either continues or worsens while on dialysis. This may be because of:
Kidney transplantation (or renal transplantation) often improves ED rates. ED prevalence dropped from 75% pre-transplant to about 59% after transplant. [9] But challenges remain:
So while a transplant may help, it’s not a guaranteed cure.
The good news is that while kidney disease and ED often go hand in hand, there are effective ways to manage both. Treatment usually works best when it tackles the problem from multiple angles. Here’s a look at the main options men can consider with their doctors.
Open conversations are important. If kidney disease or dialysis is affecting your sex life, bring it up with your doctor.
Erectile dysfunction is a common yet under-discussed complication of kidney disease. Hormonal imbalances, damaged blood vessels, nerve injury, toxin build-up, fatigue, and the emotional toll of living with CKD all combine to affect sexual function. Other conditions like diabetes, cardiovascular disease, and high cholesterol, along with certain medications and even dialysis, make the challenge even greater.
The positive news is that ED in men with kidney disease is not untreatable. From medical therapies to lifestyle changes, many approaches can improve both kidney health and sexual well-being. Regular monitoring of kidney function and open communication with healthcare providers are essential for creating safe and effective treatment plans.
For men facing this double challenge, the key message is: you are not alone, and help is available. With the right medical support, lifestyle adjustments, and emotional care, it’s possible to protect your kidneys, improve erectile function, and reclaim confidence in your sexual health.
