A meeting of experts on the subject of multiple pregnancies was held on 25 November 2005 at the invitation of the Bertarelli Foundation, Switzerland. Swiss law on reproductive medicine prohibits the selection of embryos, a situation that not only reduces the success rate of IVF, but also makes it virtually impossible to achieve a further reduction in multiple pregnancy rates resulting from IVF. The medical profession, the couples affected and the general public need to be better informed about this restrictive law. Furthermore, it is a little known fact that a considerable number of multiple pregnancies are due to simple ovulation induction.
