Physicians who are told or discover information that would be material to another party's participation in an assisted reproductive technology (ART) arrangement (such as lawyer's, donor's, gestational carrier's, or intended parent's) should encourage disclosure to that party. In some instances, it is ethically and legally permissive for the physician to either disclose material information to an affected party or to transfer care of a patient to another willing provider. In all cases involving the legal status or rights of the parties, referral to legal professionals is advised. (Fertil Steril (R) 2014; 101: 38-42.
