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:
“I think that Pilgrim’s Progress is the best sermon which has been preached from this text; almost all other sermons that I have heard, or heard of, have been but poor imitations of this.”

“come peace or war, the progress of America and Europe
Becomes a long process of deterioration—”
—Robinson Jeffers (1887–1962)
“The real grounds of difference upon important political questions no longer correspond with party lines.... Politics is no longer the topic of this country. Its important questions are settled... Great minds hereafter are to be employed on other matters.... Government no longer has its ancient importance.... The people’s progress, progress of every sort, no longer depends on government. But enough of politics. Henceforth I am out more than ever.”
—Rutherford Birchard Hayes (1822–1893)
