This population based study is aimed at analyzing the presence of congenital malformations in a large group of infants born after IVF and to compare malformation risk both(More)
OBJECTIVE To compare infant outcome after different IVF techniques. DESIGN A register study in Sweden of IVF infants compared with all infants born. SETTING National health registers. PATIENT(S) We studied 16,280 IVF infants, 30% of whom were conceived by intracytoplasmic sperm injection (ICSI). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S)(More)

METHODS The presence of congenital malformations in 15,570 infants born after IVF with an embryo transfer between April 1, 2001, and the end of 2006 were compared with all(More)

PATIENT(S) More than 16,000 children born after IVF (30% of them after intracytoplasmic sperm injection) were studied with national health registers. MAIN OUTCOME(More)

BACKGROUND Deliveries among women who had an in vitro fertilization (IVF) are characterized by increased risks for both the mother and the infant/child. Part of these effects may be due to maternal characteristics. METHODS Using reports from all clinics performing IVF in Sweden, 12 186 women who gave birth after such procedures were identified (13 261(More)
BACKGROUND Infants born after in vitro fertilization (IVF) differ from spontaneously conceived infants in a number of aspects which could increase the risk for future cerebral palsy (CP), e.g., multiple births, preterm births, neonatal complications. AIMS To follow up children conceived by IVF with respect to risk for CP. METHODS Infants born after IVF(More)
BACKGROUND Various outcomes have been described during pregnancy and among infants born to women after in vitro fertilisation (IVF) treatments. This mini-review summarises recent population-based Swedish studies about the short- and long-term effects of IVF on the infant and child, and also comments on disturbances of pregnancies and deliveries occurring(More)
During the 20 years since the first child was born in Sweden after in vitro fertilisation, clinical policy has changed. During the early 1990s, the clinics performing in vitro fertilisation and the National Board of Health and Welfare agreed to reduce the number of embryos transferred to the uterus during in vitro fer-tilisation from three to two. Here, we(More)
