Clinical strategies to avoid multiple pregnancies in assisted reproduction.
Multiple pregnancies following assisted reproductive techniques (ART) became an epidemic in the early nineties. Since then, most European countries have tried to apply restrictive policies to avoid multiples and high order multiples as far as possible. Those pregnancies may cause severe consequences to both the fetuses and mother. Economic, social and ethical dilemmas are also avoidable if caution is exercised when using ART to achieve those pregnancies. When restrictive policies are used in ovulation induction and in vitro fertilization, the results show a clear reduction in the number of MP maintaining satisfactory rates.
