Pyloric stenosis in in vitro fertilized triplets - is it a coincidence?

Abstract

Infantile hypertrophic pyloric stenosis was previously reported in multiple births, but there were only 3 triplets in the literature and all were naturally conceived. Assisted reproductive technologies, such as in vitro fertilization, are accused for increasing the risk for some anomalies in children. Triplets of in vitro fertilization, all of whom were operated on because of pyloric stenosis, are presented. (c) 2005 Elsevier Inc. All rights reserved.
