TL;DR: Subfertility is a major risk factor for adverse perinatal outcome in ART singletons, however, even in the same mother an ART singleton has a poorer outcome than the non-ART sibling; hence, factors related to the hormone stimulation and/or IVF methods per se also may play a part.

TL;DR: Data concerning infant outcome after slow freezing of embryos was reassuring, and properly controlled follow-up studies of neonatal outcome are needed afterSlow freezing of blastocyst and after vitrification of early cleavage stage embryos, blastocysts and oocytes.

TL;DR: Important contributions to the development of IVF from the Nordic countries include techniques for ovarian stimulation, sonographic techniques for monitoring and vaginal oocyte retrieval and also unique possibilities for monitoring IVF safety.

TL;DR: It is proposed that men with very low sperm counts considering ICSI should always be informed of the possibility of genetic testing and reassurance that a decision to test or not to test, or the subsequent test results will not be used as a reason for withholding treatment.

TL;DR: Different strategies to avoid multiple births in ART are discussed, including the reduction or elimination of multiple pregnancies.
