Gel Shows Promise as Future Male Contraceptive

MONDAY, July 2 (HealthDay News) -- Men may one day have a birth-control option other than the condom or vasectomy -- if early research on a new contraceptive gel pans out.

"I think [men] would use it more than is realized," said Alukal, who was not involved in the new research. "Plenty of guys are concerned about unwanted pregnancy, almost as much as women."

Unfortunately, condoms and vasectomy have remained the only commercially available contraception options for men.

The results of the study, funded by the U.S. National Institutes of Child Health and Human Development, were presented at the recent Endocrine Society annual meeting, held in Houston.

According to Wang, the gel was applied in two spots -- the testosterone component on the arm and the progestin component on the abdomen. The gels were applied every day for six months.

The study, conducted in conjunction with the University of Washington, involved 56 men who were assigned to receive one of
