The cognitive and socio-emotional development of 5-year-old children born after PGD.

Study Question: Does PGD increase the risk on adverse cognitive and socio-emotional development?

Summary Answer: The cognitive and socio-emotional development in children born after PGD seems to be normal when compared to control groups.

What Is Known Already: A limited number of studies with small sample sizes indicate that the cognitive and socio-emotional development of (pre)school-aged children born after either PGD or PGS seem to be comparable to those of children born after IVF/ICSI and to naturally conceived (NC) children from the general population.

Study Design, Size, Duration: For this study we invited 72 5-year-old PGD children, 128 5-year-old IVF/ICSI children and 108 5-year-old NC children from families with a genetic disorder.
