With condoms and vasectomies, men take responsibility for a third of contraception in the United States. But health officials would like to see that figure grow.

Several promising possibilities — from a male pill to putting a cork in it — are on the horizon, based on presentations today at the second "Future of Male Contraception" conference, held in Seattle and sponsored by the National Institutes of Health, World Health Organization and others.

They include:

Sperm blocker:

The device — a set of removable plugs — blocks sperm in the vas deferens, the tube that's cut in a vasectomy.

Testosterone-like pill:

Nonhormonal pill:

Research shows a non-hormonal compound called CDB-4022 prevents monkey sperm from swimming to their destination. Upon stopping treatment, fertility returned completely in 16 weeks

A new survey by the International Male Contraception Coalition found 61 percent of men would pick a nonhormonal drug over other contraceptive choices.
