Istanbul - The European Association of Reproductive Medicine estimates that since July 1978, when the first “test tube baby” Louise Brown was born, 5 million children worldwide have been born using assisted reproductive technology (ART). This number has now been announced on the occasion of the annual congress of the European Society of Human Reproduction and Embryology (ESHRE) in Istanbul.
By ART, ESHRE understands in vitro fertilization (IVF), in which egg and fertilize sperm cells more or less spontaneously in the test tube, and the intracytoplasmic sperm injection, ICSI, in which the Repromediziner helps with an injection needle. By the end of last year, 4.6 million children had been born thanks to ART. At some point this year, the 5 million mark will be broken, says Anna Pia Ferraretti, Bologna, who heads the ESHRE IVF Monitoring Consortium.
Although pregnancy rates have remained relatively stable at around 32 percent per embryo transfer in recent years are (more should not be possible in nature either), the repro-medicine specialists today limit themselves more often to the transfer of few or individual embryos. The result is low rate of multiple pregnancies. The proportion of twins was 19.6 percent in 2009 (more recent figures are not available). According to Ferraretti, triplet births occur in less than one percent of cases.
