Oral contraceptives might not cause weight gain

If you take birth control pills and are putting in some extra pounds, the pills might not be to blame.

Researchers in Oregon say a new study suggests that oral contraceptives don't cause weight gain.

In an eight-month study, both overweight and normal-weight monkeys were given doses of oral contraceptives equivalent to the intake of a human. The findings showed that the normal group retained a stable weight, while the obese group actually lost 8 percent of their weight, and 12 percent of their body fat.

The new study will appear in next month's issue of the journal Human Reproduction.
