In vitro fertilization in Sweden : Maternal characteristics

• 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 deliveries, 16 280 infants born). Various social and medical characteristics of the women were studied and compared with all women giving birth. Information was retrieved by interviews in early pregnancy or by linkage with various registers. Results. Women who had IVF were older than other women who gave birth and were older after standard IVF than after intracytoplasmatic sperm injection (ICSI). They were more often of first parity and smoked less than other delivered women. There were more women with high body mass index: they worked outside home less often and were more often of Swedish nationality. Women who had standard IVF had more previous miscarriages than expected, but this was not true for women who had ICSI. Their pattern of drug usage differed from that of other women who had given birth. Conclusions. Women who underwent IVF and gave birth showed marked deviations from other women who gave birth. Some of these characteristics may help to explain the increased risks associated with these procedures. Women who had ICSI were less deviating than women who had standard IVF. © Acta Obstet Gynecol Scand 2005.
