What’s Up And Coming In Male Sexual Dysfunction?

Andrew Siegel MD  5/30/15


Technological advances and innovations have occurred in the field of sexual medicine. Trending and novel approaches to ED will be reviewed and my comments will follow (in blue).

Many treatments for ED are essentially “Band-Aids” that do not correct the problem at its root cause, but manage the problem on an on-demand basis, typically beneficial for one sexual encounter. This is the case with all of the new technologies that will be discussed with the exception of pelvic floor muscle training (PFMT) and shockwave therapy, both of which provide an ED management that can be rehabilitative or curative.

Exercises To Improve Your Sexual Function

You go to the gym for cardiovascular health and strength training, but who thinks about the important group of muscles that contribute to erectile rigidiity, erectile durability, and healthy ejaculatory function?  Pelvic floor muscle training (PFMT) is a natural, safe, non-invasive means of empowering men, improving many sexual and urinary conditions. These exercises will gradually achieve the status, traction and common use in men as Kegel exercises have in women through PFMT programs like Private Gym (www.PrivateGym.com).  PFMT can help fix one of the common underlying factors that contribute to ED—poorly functional pelvic floor muscles. Impaired pelvic floor muscles promote the outflow of penile blood from the erectile chambers and result in lower erectile blood pressures and softer erections.

PFMT is strongly trending to become a routine first-line approach for the management of male sexual dysfunction. I predict that in the near future, many men with healthy sexual function will use PFMT to maintain healthy function and to help prevent  typical age-related declines, just as exercise in general is used to maintain health and wellness and slow the aging process.

External Penile Support Devices

The Erektor, manufactured by Global Life Technologies (www.erektorforlife.com), is an externally applied mechanism that provides length and rigidity to the penis. It is worn during intercourse in order to permit sufficient rigidity for penetration. It consists of two cylindrical rings attached to a rigid rod that is customized to one’s penile length. The penis is stretched and placed within the rings and the rod sits on the undersurface of the penis.

Think scaffolding…Functional, but not much of a crowd pleaser! What is she going to think? Great name, though…Erektor.

The Penile Cast is an external cast that the penis is placed into to gain the ability to penetrate. It provides rigidity to the shaft and some sensation is possible through cutouts.

Think hollow dildo. She’d probably prefer using this one alone, without you attached to it!

Penile Vibrator

Penile vibratory stimulation is a means of provoking an erection in men who suffer with ED. Additionally, it is a mechanism to provoke ejaculation in men who have a spinal cord injury rendering them incapable of ejaculating. Developed by Reflexonic (www.reflexonic.com), the Viberect was FDA approved for ED in 2011. The device has two arms that are placed in contact with the penile shaft that apply the vibrations, and the vibratory stimulation will cause an erection and ultimately ejaculation.

The company was kind enough to send me a sample device, which I have in the office. It is somewhat bulky and cumbersome, appearing like an oversized stapler. It is a bit on the noisy side, but effectively causes an erection and ejaculation. Perhaps the next generation will be smaller and quieter. It may prove useful in penile rehabilitation after radical prostatectomy.

Penile Shockwave Therapy

Shockwaves are acoustic waves carrying energy that can be focused and targeted. For many years, urologists have used shockwave therapy to pulverize kidney stones. Low intensity shockwave therapy is a novel treatment for ED that when applied to the penis causes cellular micro-trauma and mechanical stress, which causes growth of new blood vessels and improved blood flow.

It has been used in the treatment of chronic wounds, neuropathy, cardiac disease and has been recently trialed for ED. A pilot study in humans applied the shockwaves to five separate sites on the penis resulting in an increase in rigidity and durability of erections using the International Index of Erectile Function as a metric. An additional study showed positive short-term effects in men who previously responded well to oral ED medications. Clinical trials have shown both subjective improvement in ED as well as objective increased penile blood flow and erectile rigidity. Shockwave therapy has the potential of altering one of the underlying causes of the ED, poor arterial inflow of blood.

Intriguing, with promising results from preliminary trials with further clinical investigation necessary and need for optimal treatment protocols to be determined.

Impulse Magnetic Therapy

Certain types of magnetic fields are capable of enhancing blood circulation and increasing cellular oxygen uptake. Magnetic stimulation thus has the potential for inducing increased blood flow to the penis with studies suggesting that magnetic field therapy can improve ED.

Also interesting, with promising results from preliminary trials with further clinical investigation necessary and the need for intensity, frequency and duration protocols to be established.

Tissue Engineering

There is abundant ongoing research in the field of creating—in the lab—biological substitutes to replace injured, diseased or malfunctioning tissues and organs. Although the future appears encouraging, as of now there are no bioengineered tissue substitutes applicable to poorly functioning or damaged penile tissues.

Not ready for prime time when it comes to the penis.

Nanotechnology (Nanoparticle Delivery System)

Nanoparticles are packaged molecules—comparable in size to viruses—that can encapsulate biologically active materials, such as the oral ED medications or nitric oxide, the chemical mediator of erections. A gel that contains such nanoparticles can be applied to the skin of the penis to achieve an erection. This has the potential advantage of the active medication being delivered to the target organ and not distributed throughout the body, avoiding side effects. To date this technology has only been tested in laboratory animals.

Any word preceded by “nano-“ sounds very cutting edge and high tech! Great concept, but who knows? Human clinical trials need to be performed. Testing has resulted in excellent quality erections in our rat friends.

Endovascular Treatment

One cause of ED is blockage of pelvic arteries by fatty deposits, which do not permit sufficient blood flow to achieve an erection. Endovascular treatment is a non-invasive therapy of focal vascular lesions (small and localized areas of arteries that are clogged), an alternative to open surgery to bypass obstructed vessels. A drug-eluting stent (a device that not only bypasses an obstruction, but also releases medication) is placed in a blocked internal pudendal artery. The stent elutes Zotarolimus, a medication that is used to prevent the artery from reblocking. An initial clinical trial has shown improvement in ED in appropriate patients with focal vascular lesions.

In a patient with arteriogenic ED due to pudendal artery blockage, this may prove advantageous, just as drug-eluting stents have been beneficial for coronary artery blockages that would otherwise have required open coronary bypass. The jury is still out, with expanded clinical trials necessary.

The “P-Shot”

Named after the Greek God of Fertility, the Priapus Shot or the “P-Shot” claims to increase the size of the penis by 10-20% and produce harder and longer lasting erections. Platelet rich plasma (PRP) is extracted from the patient’s own blood and injected into the penis. The patient is required to use a penis pump over the course of the treatment. The premise is that growth factors in the PRP promote the growth of new blood vessels to the penis. Providers of the P-Shot claim it is the most significant advancement in cosmetic surgery in decades.

The claims are anecdotal, hypothetical, with little scientific research and evidence supporting them. The jury is still out on this one, but it sure sounds interesting.

Wishing you the best of health,
