title: Can we sense ART? The blinded examiner is not blind-a problem with follow-up studies on children born after assisted reproduction.
abstract: In a prospective, controlled, blinded follow-up study of children born after intracytoplasmic sperm injection (ICSI), blinded examiners correctly intuited the mode of conception (ICSI versus spontaneous) in three out of four children, which must be considered when interpreting outcome data for children born after assisted reproduction.
