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.
