We report a case of late pregnancy following in vitro fertilization, complicated by severe early preeclampsia in a 45-year-old primigravida. The treatment was conservative for two weeks and then the pregnancy was terminated by caesarean section in view of the worsening of the clinical and biological parameters. The maternal prognosis was favorable. As for the perinatal prognosis, it resulted in prematurity, intrauterine growth retardation and neonatal respiratory distress requiring transfer to neonatal intensive care. Thus, when a couple wishes to have recourse to IVF or ICSI for a late pregnancy, health professionals must inform them of the probable increases in the risks for the woman but also for the child.
