Erectile dysfunction (ED) rings are bands that fit around the base of the penis. A ring may help maintain an erection by slowing the flow of blood from the penis.

ED can develop at any age. It affects 32–80% of males, depending on the age group. It is more common in older adults and those who have certain health conditions or are taking certain medications.

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

In this article, we describe how these rings work and list some of the best options.

Sex and gender exist on spectrums. This article will use the terms “male,” “female,” or both to refer to sex assigned at birth. Click here to learn more.

Quick links

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

The ring fits around the base of the penis. Some also have a second ring, called a penoscrotal ring, that fits around the testicles. And some ED rings have features that stimulate a partner’s clitoris.

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.

But other research indicates that combining ED medication with a device such as a pump or ring can significantly improve erectile function.

The Urology Care Foundation reports that using an ED ring and a pump is effective and safe. And older research supports the use of ED drugs and penoscrotal rings as a way to have reliable erections.

ED occurs when blood flows out of the penis too quickly for the person to have or maintain an erection. A ring applies pressure to the area around the base of the penis, and in some cases, the penis and testicles.

This pressure causes the blood vessels to tighten, slowing the flow of blood away from the penis. This helps the penis stay erect for longer.

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

For people looking for ED rings, the following are some options to consider. But a doctor can describe the best approach to ED treatment and provide further advice.

LELO TOR 2 Couples’ Ring

Best vibrating ring

ED rings are straightforward to use for most people:

  1. Use a lubricant to help slide the ring on and off.
  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 — to latex, for example. And 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, or 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.

To prevent these issues:

  • Use a properly fitting ring.
  • Keep it on for no longer than 30 minutes.
  • Never fall asleep with the ring in place.
  • Avoid using an ED ring while using drugs or alcohol.
  • Remove the ring immediately if pain, numbness, or unusual sensations occur.
  • If the penis swells and the ring will not come off, seek emergency care.
  • Avoid using metal rings.

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, contact a medical professional immediately to avoid potentially severe complications.

Overall, it is best 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:

  • Vacuum erection devices: Also known as penis pumps, these draw blood into the penis to cause an erection. Some research indicates that satisfaction rates among users range from 27–94%. Learn more here.
  • Medications: These improve blood flow to the penis, and some options include tadalafil (Cialis), vardenafil (Levitra), sildenafil (Viagra). About 70% of people respond well to the oral versions of these drugs. Some injectable forms are also available. Learn more here.
  • Lifestyle changes: The following may improve ED:
    • having a healthy, balanced diet
    • exercising regularly
    • limiting alcohol intake
    • maintaining a moderate weight
    • managing stress
    • quitting smoking
  • Natural remedies: If a person is taking a medication that can increase the risk of ED, they should speak with a healthcare professional about alternatives. Read about natural remedies for ED here.
  • Penile implants: Having penile implant surgery may help some people with ED. Learn more here.
  • Counseling: Issues concerning relationships, anxiety, and other mental health conditions can affect the ability to have and maintain an erection. A person might try counseling alone or with a partner. Learn about online therapy here.

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

A person might feel embarrassed if they have trouble with an ED ring. This should never keep someone from seeking emergency medical care, particularly if they are having difficulty removing a ring.

Difficulty having or maintaining an erection can also be difficult to speak about. But a range of 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, which in turn has associations with an increased risk of death, there is no direct correlation.

The following are answers to common questions about ED rings:

Do ED rings work?

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

The Urology Care Foundation reports that using an ED ring at the same time as a vacuum erection device is effective and safe.

How do you 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. Wash and dry ED rings carefully and replace them regularly.

Are ED rings safe?

ED rings that are not made of metal are usually safe if a person uses them correctly.

But it is best 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.

Remove an ED ring immediately if there is any numbness or pain. In rare cases, an ED ring can get stuck, 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 important to consider the flexibility and fit and avoid rings made of metal.

Remove an ED immediately if it causes pain, irritation, or other unusual sensations. Do not leave any ring on for more than 30 minutes.

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