Calhaz–Jorge C, et al. – Here, researchers want to know whether there are any changes in the treatments involving ART and intrauterine insemination (IUI) initiated in Europe amid 2013 compared with previous years. An increase in the overall number of ART cycles resulting from a higher number of countries reporting data was evident, the pregnancy rates (PRs) in 2013 remained stable compared with those reported in 2012, the number of transfers with multiple embryos (3+) was lower than ever before yet the multiple delivery rates (DRs) remained unchanged, and IUI activity and success rates were similar to those of last years.
