Erectile dysfunction (ED) rings are bands that fit around the base of the penis and help maintain an erection by slowing blood flow from the penis. Research shows that ED rings can work effectively in many cases.

This article contains studies showing images of injury and surgical processes.

ED can develop at any age. A 2022 article estimates that around 52% of men in the United States aged between 40 and 70 years have ED. Worldwide, there are at least 150 million males living with ED. It is more common in older adults, those who have certain health conditions, and people who are taking certain medications.

ED can have a significant effect on mood, self-esteem, and relationships. An ED ring may be an inexpensive, effective solution for some people.

This article describes how these rings work and lists some of the best options a person can consider online. It also discusses alternative treatments for ED, when to see a doctor, and answers some frequently asked questions.

A quick look at the best ED rings

ED occurs when blood flows out of the penis too quickly for the person to have or maintain an erection.

An ED ring fits around the base of the penis, applying pressure to the area. Some also have a second ring — a penoscrotal ring — that fits around the testicles. ED rings can also have features that stimulate partners with a clitoris.

Putting an ED ring on the penis increases pressure, which causes the blood vessels to tighten, slowing blood flow away from the penis. This helps the penis stay erect for longer.

ED rings usually consist of rubber, plastic, or silicone. Some are metal, but the reduced flexibility can increase the risk of complications, so a person should avoid metal rings.

Other names for ED rings include:

  • cock rings
  • constriction bands
  • penis rings
  • tension bands
  • tension rings

Penis rings are an essential part of vacuum therapy systems, also known as penis pumps. A pump helps a person have an erection, while a ring helps maintain one.

Limited studies have explored rings alone as an ED treatment.

The Urology Care Foundation (UCF) reports that using an ED ring and a pump is effective and safe.

A 2022 case report and literature review also claimed that ED rings can be effective in improving ED and other sexual health issues, such as climacturia, which is when a person leaks urine as they ejaculate.

However, the case report notes the dangers of using metal penis rings, which can cause severe health complications if they become stuck.

If a person gets their penis stuck in an ED ring, they should seek immediate medical assistance.

ED rings work best for people with ED who can get an erection but not maintain it. However, they do not work for everyone.

  • Materials: proprietary elastomer
  • Sizes: one size, dimensions not stated

This ED ring is reportedly easy to take on and off. The company states that a person can comfortably put on this ring with an erection.

The company states it slows the blood flow leaving the penis, prolonging erections and delaying orgasm.

It consists of a soft, proprietary elastomer material. Although Firmtech does not say exactly which material it uses for this ring, it advises that a person should not use a silicone-based sanitizer to clean the ring.

The company states this ED device has Food and Drug Administration (FDA) registration.

  • Price: from around $19–40

  • Sizes: two diameters, four tensions

The brand makes this tension ring from a latex-free gel. It has bumps that apply pressure to veins in the penis and a notch that the company claims aids ejaculation.

The manufacturer says it is comfortable, safe, and effective. However, it is not adjustable.

To get the right size, a person needs to measure the diameter of their penis and work their way down the sizes until they find one that provides enough tension for them to maintain an erection.

The sizes are as follows:

  • Pink: This ring is high tension and comes in a 19 or 22-millimeter (mm) diameter. The company calls the 19 mm ring a medium and the 22 mm ring a large.

  • Gray: This ring is low tension and comes in 19 or 22 mm diameter.

A person can use the ring on its own or in various combinations, even with a vacuum pump. As such, it may be a suitable choice for people with moderate to potent ED when combining it with other products or medications.

The rings cost $40 individually, but a pack of four costs between $19 and $22.

It consists of silicone, and a person can wear it in four different ways. It aims to make erections last longer and delay orgasm.

The app also allows for remote control, so this ring is also suitable for people in long-distance relationships.

The manufacturer states this ring is waterproof.

ED rings are straightforward to use for most people:

  1. Use a lubricant to help slide the ring on and off. Make sure the lube is appropriate for the ring material.
  2. Gently place the ring over the head of the erect penis and move it down to the base.
  3. Take care to avoid snagging the ring on pubic hair.

After use, wash the ring carefully in warm, soapy water and allow it to air dry.

When selecting an ED ring, a person may want to consider:

  • The material: This is especially important for people with sensitivities or allergies — for example, latex. A first-time user might try a flexible silicone ring before moving on to a more rigid one. Some materials are also easier to clean than others, and customer reviews may provide more detail.
  • The fit: A ring should apply just enough pressure to keep blood in the penis without causing pain or damage. If someone is unsure what size to get, an adjustable or flexible silicone ring is a good option.
  • Pleasure features: Some ED rings vibrate or have other features that provide penile and clitoral stimulation.

When using an ED ring, there is a risk of:

  • pain
  • numbness
  • a “pins and needles” sensation
  • bruising
  • swelling

Also, if the ring fits incorrectly or stays on for too long, this can lead to necrosis, which is tissue death. It occurs when new blood-carrying oxygen cannot flow into the penis.

In severe cases, necrosis can lead to gangrene and the need for amputation.

A person can help prevent these issues by:

  • using a properly fitting ring
  • keeping it on for no longer than 30 minutes
  • refraining from falling asleep with the ring in place
  • avoiding using an ED ring while using drugs or alcohol
  • removing the ring immediately if pain, numbness, or unusual sensations occur
  • seeking emergency care if the penis swells and the ring will not come off
  • avoiding using metal rings

The study below contains graphic images.

If a person cannot or does not remove their ED ring within 30 minutes, this could cause what doctors refer to as “penile ring entrapment,” or PRE. If this happens, an individual must contact a medical professional immediately to avoid potentially severe complications.

Overall, it is best for people to speak with a healthcare professional before using an ED ring or any other ED device. These rings may not be suitable for everyone, including people with blood clotting disorders, other blood disorders, or people taking blood-thinning medications.

A person might try any of these other ED treatments:

Some of these approaches might be more effective in combination with an ED ring.

A person might feel embarrassed if they have issues with an ED ring. This should not keep someone from seeking emergency medical care, particularly if they have difficulty removing a ring.

Difficulty having or maintaining an erection can also be challenging to speak about for some people. However, various approaches can help, including lifestyle changes, medications, and devices.

A doctor can help determine whether ED stems from a medical condition, such as:

Also, ED may be a risk factor for cardiovascular disease. But while ED can be a marker for this disease, there is no direct correlation.

Below, we answer common questions about ED rings.

Do ED rings work?

Research is limited, but anecdotal evidence suggests they work for many people with ED. In some form, rings or bands have been in use for hundreds of years.

The UCF reports that using an ED ring simultaneously as a vacuum erection device is effective and safe.

How do people use ED tension rings?

A person places the ring at the base of the penis. Depending on the type of ring, the penis can be either flaccid or erect. The pressure from the ring tightens the veins in the penis.

This keeps blood in the penis, which helps maintain an erection. Some manufacturers say that their products do not tighten the arteries, allowing blood to flow into the penis.

A person removes the ring — within 30 minutes — by loosening the band or sliding the ring off. They should then wash and dry the ring carefully and replace it regularly.

Are ED rings safe?

Nonmetal ED rings are usually safe if a person uses them correctly.

It is best for people to speak with a healthcare professional about the most appropriate ED treatment, particularly for people who have a blood clotting disorder or take any medication.

A person should remove an ED ring immediately if there is any numbness or pain. An ED ring can get stuck in rare cases, and immediate medical care is necessary.

ED is a common condition, especially among older adults, but it can affect males of any age. Penis rings can help some people maintain an erection, and a person might use them in addition to ED medications, a vacuum pump, or both.

Many types of ED rings are available. It is essential for people to consider the flexibility and fit and avoid metal rings.

A person should remove an ED immediately if it causes pain, irritation, or other unusual sensations. They should not leave any ring on for more than 30 minutes.

If ED rings do not work, many other treatments are available. A healthcare professional can recommend an effective approach and rule out underlying health conditions.
