Botox for Penis: Procedure, Treatment, Results & Benefits

When we think of Botox, wrinkles and lines are often the first things that come to mind. A potent muscle relaxer, Botox is typically used to reduce signs of aging, such as forehead lines, glabellar lines and lateral canthal lines, or crow's feet. It is also used clinically to treat a wide range of medical conditions, including spasticity, overactive bladder, migraines, blepharospasm, urinary incontinence and cervical dystonia.

Botox is often used off-label for both aesthetic and medical purposes. This includes the treatment of acne, TMJ syndrome, hyperhidrosis (excessive sweating), and penis enhancement. It's also a promising treatment for premature ejaculation.

Botox for penis enhancement 

Scientists discovered the penis-enlarging properties of Botox accidentally. In a study published in the Journal of Sexual Medicine, Botox injections were administered to the base of the penis to treat hyperactive retraction reflex (a medical condition that causes the penis to retreat when the patient is stressed out or cold). Through muscle paralysis, Botox successfully prevents the penis from retracting in cold conditions. More importantly, researchers discovered a valuable side effect—the length of the flaccid penises was increased by half an inch. It is important to keep in mind that Botox has no effect on the size of an erect penis.

Who should use it?

Various studies have found that a large percentage of men are not only insecure about their penis size, but willing to have Botox injected in their penis. Previously, many of theese men had resorted to questionable treatments in the pursuit of a larger penis, such as penis weights, pumps, and an exercise known as jelqing. Some of these treatments have not been scientifically verified and could potentially be dangerous.

Botox offers a considerably safer way of enhancing the penis. From erectile dysfunction to penis enlargement, Botox is effective for almost all phallic imperfections. Botox is also suitable for patients who suffer from premature ejaculation.

Botox injections are particularly useful for patients who are unable to take erectile dysfunction drugs such as sildenafil (more commonly known as Viagra). While reasonably effective, Viagra may interact with many other medications, including calcium channel blockers, HIV protease inhibitors, macrolide antibiotics, aripiprazole, azole antifungals, amiodarone, phosphodiesterase 5 inhibitors and statins. Viagra is contraindicated for patients who are on nitrate medications such as isosorbide dinitrate and nitroglycerin. 

How does it work?

Botox is formulated with botulinum toxin type A, a type of neurotoxin that has muscle relaxant effects. The science behind Botox is fairly simple: it inhibits muscle contractions. Once administered, Botox binds to the motor nerves (or more specifically, the cholinergic receptors) to inhibit the release of acetylcholine, a type of neurotransmitter that plays a role in muscle contractions. This leads to decreased muscle activity. When used for wrinkle treatment, Botox prevents the contraction of underlying muscles (which is known to cause surface wrinkles). In this case, Botox helps to relax the penile muscles, which promotes blood flow.

In an animal study, Botox has been shown to significantly enhance the sexual performance of rats. Compared to a control group, rats that have had Botox are able to last for 3.5 minutes longer before ejaculating. Having dramatic sexual enhancing effects, Botox is poised to revolutionize the treatment of premature ejaculation. Premature ejaculation occurs when the patient ejaculates too soon (typically less than 1 to 3 minutes). While highly prevalent, premature ejaculation is often poorly managed. The treatments are not always effective, and it usually takes a combination of different treatments to see results. It is believed that Botox exerts an inhibitory effect on the bulbospongiosus muscle (which controls ejaculation and erection) to delay ejaculation.

How long do the results last?

The results of treating the penis with Botox Botox typically last for 4 to 6 months, after which the results will disappear. Repeat treatments are required to maintain the results.

Is it safe?

When used correctly, Botox for the penis is generally safe and well tolerated. It is not known to migrate from the injection site, which means that it will remain localized to where it is injected. Having said that, Botox can travel up to 3cm from the point of injection.

Botox is unlikely to cause numbness. This is because Botox only acts on motor nerves and does not affect the muscles that control sensation.

Practitioners should be extra cautious to minimize the risk of side effects. Prior to injection, patients should be made aware of the fact that Botox is being used off label. Patients should only proceed with the treatment if they find the potential risks acceptable. While the findings from clinical trials are mostly positive, side effects such as prolonged erection have been reported.

It is not advisable to use Botox in patients who have a known allergy to botulinum toxin or any other inactive ingredient in the formulation. In general, Botox is intended for adult patients of more than 18 years of age (except when used in the treatment of lower limb spasms).
