A third theory is based on the fact that the active ingredients in oral contraceptives – the hormones estrogen and progesterone – are stored in body fat. "The more fat a person has, the more likely the drug is sequestered, or trapped, in the fat instead of circulating in the bloodstream," (epidemiologist Victoria) Holt said.
