Developmental outcomes at one and two years of children conceived by intracytoplasmic sperm injection.

Background: Present opinions regarding developmental delay of children conceived with intracytoplasmic sperm injection (ICSI) are variable and without consensus.

Methods: We compared developmental outcome at 1 and 2 years of 50 children conceived by ICSI with 51 spontaneously conceived children. Assessments were performed using the Bayley Scales of Infant Development for motor and mental development and quality of behavior, and the CARE-Index for the quality of parent-child interaction.
