The practice of screening potential users of reproductive services is of profound social and political significance. Access screening is inconsistent with the principles of equality and self-determination, and violates individual and group human rights. Communities that strive to function in accord with those principles should not permit access screening, even screening that purports to be a benign exercise of professional discretion. Because reproductive choice is controversial, regulation by law may be required in most jurisdictions to provide effective protection for reproductive rights. In Canada, for example, equal access can, and should be, guaranteed by federal regulations imposing strict conditions on the licences of fertility clinics.
