title: [Prevention of iatrogenic multiple pregnancies].
abstract: A significant increase of twin and multiple pregnancies induced by infertility treatment has been observed. These high-risk pregnancies should be efficiently prevented. Gonadotrophin treatment for anovulation being the main culprit, it should be undertaken: 1) if other induction methods have failed. 2) under strict echographic and hormonal monitoring. After in vitro fertilization, number of embryos replaced should be selectively limited (to 2 or 3) on the basis of their vitality scores. Partial reduction of a multiple pregnancy should remain an exceptional solution.
