Fertility treatment and risk of childhood and adolescent mental disorders: register based cohort study.

After stratification, we found that the increased hazard ratios for mental disorders within these categories were more consistent in boys than in girls, in whom they fell short of significance for hyperkinetic disorder, tic disorders, and conduct, emotional, or social disorders.

Results The risk of mental disorders in children born after in vitro fertilisation or intracytoplasmic sperm injection was low, and was no higher than in spontaneously conceived children, except for a borderline significant increased risk of tic disorders (hazard ratio 1.40, 95% confidence interval 1.01 to 1.95; absolute risk 0.3%).
