Success of infertility treatments in Finland in the period 1992-2005.

OBJECTIVES: The objective was to study the success rates of infertility treatments in the period 1992-2005 in public and private clinics. STUDY DESIGN: Aggregate IVF statistics (1992-2005) and nationally representative cross-sectional survey (2002). RESULTS: The success rates of infertility treatments remained stable, despite a substantial increase in single-embryo transfers. In 2005, the clinical pregnancy rate was 23/100 initiated cycles and a live birth rate of 17/100 cycles. The proportions of term singletons and singletons weighing at least 2500g improved over time and both rates were 14/100 in 2005. Pregnancy rates improved most among older women during the study period. The success rate in the private sector was significantly better than that in the public sector among women younger than 35 years. CONCLUSION: The single-embryo policy has not decreased pregnancy and birth rates. The proportions of term singletons per initiated cycle and singletons weighing at least 2500g per initiated cycle have improved over time. The higher success rate in the private sector may be because of different clientele.
