Lagging libidos have become big business for large pharmaceutical companies. It seems there's been a whole new crop of these drugs hitting the marketplace just in the past few years. In a way, this is good news, because it means more men are taking steps to address their sexual issues, whereas in the past they may have just suffered in silence and learned to live with it. Still, some experts believe that the vast majority of erectile dysfunction goes undiagnosed.

Viagra

Probably the most well-known of the sexual enhancement drugs is Viagra. It is the most widely prescribed drug for male erectile dysfunction. The pills are easily recognizable, thanks to their blue color and diamond shape.

Just a reminder: Prescription drugs used to treat sexual problems can have negative interactions with other medications. Before you take Viagra or a similar drug, make sure to tell your doctor about any other medications (both prescription and over-the-counter) you take, to avoid any serious problems.

Natural Viagra?

Recently, there's been a trend in which stores — especially online shops — will tout certain herbs or other substances as natural Viagra. Take these claims with a big grain of salt and a lot of caution. At best, the claims of these substances' sexual powers are probably greatly exaggerated. Worse, these substances can be potentially dangerous. Unlike prescription medications, herbs and supplements don't have to be evaluated by the Food and Drug Administration or any other regulatory agency.

Female Viagra?

With all this attention focused on Viagra and similar drugs for men, many women have been demanding a similar magic pill that can work wonders for them in the bedroom. Alas, that seems to be a way off in the future. Several drug companies have claimed to be in the process of developing a drug that will help improve women's experiences, but so far no such wonder drug has hit the market.
