Assisted reproduction techniques (ARTs) allow women of advanced reproductive age to become pregnant. One of the most frequent complications of ART is twin pregnancy. Cases where both factors are present represent a specially vulnerable population for obstetric complications and medical perinatal and post-partum consequences for both the mother and babies. Pre-existing medical conditions are more frequent at advanced age, and the pregnancy physiological changes and the high metabolic demand associated with a twin pregnancy may reveal or worsen any previous disease. A careful counselling process is very important in this population and certain obstetric interventions might be particularly addressed to it. Single embryo transfer should be strongly enforced in advanced age women to minimise risk for the mother and children.
