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.

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:
“All our progress is an unfolding, like the vegetable bud. You first have an instinct, then an opinion, then a knowledge, as the plant has root, bud, and fruit. Trust the instinct to the end, though you can render no reason. It is vain to hurry it. By trusting it to the end, it shall ripen into truth, and you shall know why you believe.”
—Ralph Waldo Emerson (1803–1882)
“In progress of time, when my mind was, as it were, strongly impregnated with the Johnsonian æther, I could, with much more facility and exactness, carry in my memory and commit to paper the exuberant variety of his wit and wisdom.”
—James Boswell (1740–1795)
“The progress from an absolute to a limited monarchy, from a limited monarchy to a democracy, is a progress toward a true respect for the individual.”
—Henry David Thoreau (1817–1862)
