Quintuple pregnancy is expected about once in forty million births according to calculation by the Hellin ratio.1 Foster and Carson2 collected thirty-two authentic reports of quintuplets from the literature up to 1923. Since that time we have found reports of two more,3 including the Dionne quintuplets. Ours makes the total of reported cases thirty-five.
