Key Takeaways
-
Penile injections are a quick and effective treatment for erectile dysfunction (ED). They help increase blood flow to the penis and usually work within 5 to 15 minutes.
-
The injection is self-administered on either side of the penis shaft. It’s important to avoid major blood vessels and switch sides each time to reduce the risk of scar tissue.
-
These injections are generally safe, but you should get immediate medical help if an erection lasts longer than 4 hours, or if you have ongoing pain or bleeding.
Erectile dysfunction (ED) is a condition where a man finds it hard to get or maintain an erection firm enough for sexual activity.
There are several ways to treat ED, including lifestyle changes, counseling, oral medicines, surgery, and penile injection therapy.
Penile injections can usually be given at home by the patient himself. They work by increasing blood flow to the penis, helping achieve a stronger erection.
Although the idea of injecting the penis may sound uncomfortable or scary, studies show that this treatment is generally effective and well tolerated by most men.
What Is an Erectile Dysfunction Injection?
Erectile dysfunction (ED) injections are medicines that come in a small vial. The medication is drawn into a syringe and injected into the middle area of the penis. This placement helps the medicine work effectively while reducing the risk of affecting nerves or blood vessels.
The injection increases blood flow to the penis, helping produce an erection within about 5 to 15 minutes.
This is considered one of the fastest-acting treatments for ED. Other common treatments, such as Viagra, Sildenafil, may take around 30 to 60 minutes to start working.
How to Administer an Injection
Your first injection should always be done at your doctor’s office under supervision. The doctor will teach you the correct way to give the injection and how to safely do it at home.
Before starting, wash your hands well and place all supplies on a clean surface. You will need:
-
One medication vial
-
One sterile syringe
-
Two alcohol wipes
-
A sharps container for used syringes. A medically approved container is best, but if you don’t have one, you can use a strong plastic bottle with a lid, such as an empty detergent bottle.
After filling the syringe with the medication, gently hold the head of the penis between your thumb and finger and pull it straight outward. If you are uncircumcised, pull the foreskin back first before holding the head of the penis.
Locate an area on either the right or left side of the middle part of the penis for the injection. The injection should only be given on the sides of the shaft. Avoid the top side, where major blood vessels are located, and the bottom side, where the urethra runs.
Switch sides each time you inject to help prevent scar tissue from forming. Also, avoid any area where you can clearly see a blood vessel.
After choosing the spot, clean it with an alcohol wipe. Then release the head of the penis and hold the syringe with both hands.
Remove the syringe cap and check that the correct dose is in the syringe and that there are no air bubbles. Hold the syringe with one hand, similar to how you would hold a dart.
With your other hand, gently pull the head of the penis straight outward again. Hold only the head so that you do not pull the skin along the shaft.
Place the needle against the selected area at a slight angle and carefully insert it into the shaft. The syringe should be angled slightly upward.
Press the plunger firmly to inject all of the medication. Once the syringe is empty, pull the needle straight out quickly.
Apply gentle but firm pressure to the injection site for about 2 to 3 minutes to reduce the chance of bleeding or bruising.
What to Expect
Generally, an erection occurs within 5 to 15 minutes after the injection. However, some people may also need sexual stimulation or foreplay to achieve an erection.
The erection usually lasts around 30 to 60 minutes, but this can vary depending on a person’s overall health and other individual factors.
Some people report changes in penile sensation or in their ability to ejaculate after injections. However, these effects are often related to the underlying cause of erectile dysfunction rather than the injection itself.
Who are penile injections for?
Penile injections are used for people who have difficulty getting an erection, achieving enough firmness for sexual intercourse, or maintaining an erection for the required duration. For individuals with erectile dysfunction (ED), these injections can be a highly effective treatment and often work faster than other options.
However, they are not suitable for everyone. People with mild ED usually do not need them because the medication may be too strong for their condition. They are also not recommended for those who may have trouble correctly performing the injection.
Examples of people who should avoid penile injections include:
-
People with limited finger movement or poor hand control, as they may struggle to handle the syringe or inject properly
-
Individuals taking certain blood-thinning medications
-
Those with significant scarring in the penis, which can make it difficult to find a safe injection site
-
Anyone who is uncomfortable with needles or feels anxious about using them
Penile injections may also be considered if other ED treatments have not worked well. Since they require a prescription, it is important to consult a doctor about your symptoms so you can decide together whether this treatment is suitable for you.
