Treating Erectile Dysfunction


Occasional failure to achieve an erection can occur for a variety of reasons. Failure to achieve an erection less than 20% of the time is not unusual and typically does not warrant treatment. However, a failure to achieve an erection more than 50% of the time is indicative of a problem than may cause stress, relationship problems, and self-confidence issues and requires medical attention.

Traditional Treatment Options & Limitations

For most men facing ED, the first course of treatment prescribed by a doctor is usually a course of PDE5 inhibitors.

What are PDE5 Inhibitors?

Following sexual stimulation, PDE5 inhibitors increase blood flow to the penis, causing an erection. Brand names include Viagra, Cialis and Levitra.

While PDE5 inhibitors, such as Viagra and Cialis, provide many with relief from erectile dysfunction, they are far from a universal solution for ED.

Over a third of the 300,000 men diagnosed annually with ED in the U.S. do not respond to conventional treatment.

Some men are not able to take PDE5 inhibitors due to certain medical conditions, including severe heart disease, a recent heart attack, stroke, irregular heart rhythms, uncontrolled high or low blood pressure, severe liver or kidney disease, or eye problems, such as retinitis pigmentosa.

Other men find that the PDE5 inhibitors become less effective over time as their body builds up a tolerance to them.



Just as stem cells are being used to heal and treat a variety of neurological and orthopedic conditions, urologists have also been using adult stem cell therapy to treat erectile dysfunction for patients who have been unresponsive to traditional ED treatment.
