Δ For treatment of polycystic ovary syndrome in adolescents, UpToDate authors prefer COCs with at least 30 mcg of ethinyl estradiol; this table lists a selection of such formulations with example brand names available in the United States. Adults with polycystic ovary syndrome may be managed differently; refer to related UpToDate content.
