Progress
As of 2005, human clinical trials are being performed to evaluate its effectiveness as a contraceptive. One version is currently in research and development by Shepherd Medical in Vancouver. Another version currently being researched in China is an elastomer plug device, using medical-grade polyurethane (MPU) and silicone rubber (MSR) injected as a liquid.
The U.S. Food and Drug Administration (FDA) approved human clinical trials for the intra-vas device in 2006.

Famous quotes containing the word progress:
“In fast-moving, progress-conscious America, the consumer expects to be dizzied by progress. If he could completely understand advertising jargon he would be badly disappointed. The half-intelligibility which we expect, or even hope, to find in the latest product language personally reassures each of us that progress is being made: that the pace exceeds our ability to follow.”
—Daniel J. Boorstin (b. 1914)
“A party of order or stability, and a party of progress or reform, are both necessary elements of a healthy state of political life.”
—John Stuart Mill (1806–1873)
“Social and scientific progress are assured, sir, once our great system of postpossession payments is in operation, not the installment plan, no sir, but a system of small postpossession payments that clinch the investment. No possible rational human wish unfulfilled. A man with a salary of fifty dollars a week can start payments on a Rolls-Royce, the Waldorf-Astoria, or a troupe of trained seals if he so desires.”
—John Dos Passos (1896–1970)
