More then 15 million men in U.S are affected by sexual dysfunction. Treatment for impotency varies form case to case, depending on the cause. Treatments for erectile dysfunction wary from surgical, mechanical devices to prescription drugs. In last couple of years oral medication has been the treatment of choice. Drugs like Cialis (Tadalafil) and Viagra (Sildenafil) have revolutionized the treatment of impotency.
Erection is very complex process and if anything goes wrong in the process erection might not happen or it might not be sufficient for sexual act to be preformed. The penis contains two cylinders of sponge-like tissue that run along its shaft, parallel to the urethra. When a man is sexually excited blood flows into this tissue and it increases in size. As the tissue fills with the blood, it stiffens to create an erection. Erection is maintained by continued increased blood flow to this area. Once ejaculation occurs, or after sexual excitation stops, the blood flow decreases. If any of these steps are interrupted in any way erection might not happen.
In recent times new treatments have appeared on the market. They include some over the counter medication and herbal supplements. The following are some alternatives on the market.
Yohimbe - Yohimbe is similar to yohimbine. This herbal supplement is derived from the bark of a West African tree. Side effects include nausea, insomnia, nervousness, and dizziness. Large doses of yohimbe can increase blood pressure and heart rate and may cause kidney failure. The effectiveness of this supplement has not been scientifically proven.

Some herbs and chemical compounds are not even known to regulators and their complete effect on body chemistry is unknown.
