Parents' concerns regarding their ART children.

A cohort of children conceived by assisted reproductive therapy (ART)--in vitro fertilisation (IVF) and intra-cytoplasmic sperm injection (ICSI) has been followed up in a National Child Development Study (Sutcliffe et al. 1999, 2001 and Bonduelle et al. 2005). Their parents were contacted and asked questions designed to elicit any concerns on their part about their child. 329 replies were received (90% response rate), and 86 of the families posed additional questions. We found that a small number of parents (26% of respondents) raised questions about a variety of issues regarding their ART-conceived child. The most commonly expressed theme (8% of all respondents, or 27/86 (31%) of the respondents with questions) pertained to their child's future fertility. This question was asked more frequently by ICSI than IVF parents.
