After the spectacular success shown by Viagra in rescuing males from the grip of impotency across the world, the pharmaceutical world is eagerly looking for a female viagra to treat diminishing female libido for the reason that sex therapists have found "lack of desire" to be a frequent complain from women.

The erectile dysfunction drug viagra was initially tested on women and when viagra was experimented on women it became evident that viagra didn't prove effective in increasing female sexual desire but enhanced engorgement of virginal tissue. It was observed that the enhancement of pelvic swelling caused by viagra administration on women didn't led to an increase in sexual desire.

Efforts to discover a suitable Viagra for women led to the manufacture of Intrinsa, a testosterone patch which on administration, delivered small transdermal pulses of the sex hormone thought to influence male and femalelibido. This Procter & Gamble's product was refused approval by Food and Drugs Administration on account of medical risks offered by the drug.

A compound called bremelanotide, which is a synthetic version of a hormone involved in skin pigmentation has shown clinically satisfactory results in increasing female sexual libido and more research is being carried on the drug at 20 American centres to evaluate its clinical efficacy in increasing female libido. In these experiments, the researchers are mainly adjusting bremelanotide dosages to evaluate whether it is possible to derive an effective response from the drug with minimum side-effects.
