Experts say future choices will extend beyond condoms, vasectomy

SATURDAY, April 12 (HealthDay News) -- For now, men who want to do their part for birth control have meager choices: A vasectomy -- meant to be permanent -- and condoms.

For years, experts have predicted that male contraception is under development and that more choices will be here soon.

But when? Experts agree it's still a ways off, but it's getting closer.

"It has been slow," said Dr. Ronald Swerdloff, a researcher in the quest to find feasible male contraceptive methods. But there are good reasons for that slow pace, added Swerdloff, an endocrinologist and chief of the division of endocrinology at Harbor-UCLA and professor of medicine at the Harbor-UCLA Medical Center in Los Angeles.

Pharmaceutical companies are reluctant to take on a new product quickly because of untested liability issues, he said. And "one of the biggest single issues has to do with the fact that contraception in general is a difficult area it would be used by large numbers of healthy individuals." The safety threshold, he noted, is high. Still, he added, more options are moving closer.

"If we really focus on studies, with funding, it could be four or five years" before more options might be available, said Elaine Lissner, director of the Male Contraception Information Project, a San Francisco-based organization.

The problem, she added, is that the research has been scattergun. "If we [continue to] do a study here, a study there, as we have for the last 20 years, it could take forever."

At a "Future of Male Contraception" conference, sponsored by the U.S. National Institutes of Health in Seattle, a variety of methods were reviewed, including:

• Hormonal therapy and testicular warming -- Swerdloff and his team found that giving men testosterone and another hormone with testicular warming helped suppress sperm.
