The amount of oestrogen the birth control pill currently contains is already substantially lower than it was when the pill was first licensed more than 60 years ago. But a new paper has suggested that the doses of both oestrogen and progestogen in the pill could be significantly reduced and still work to prevent pregnancy.
Given the many side effects that can come from using contraceptives, researchers wanted to know whether birth control could still work even if hormone dosages were lower.
