%X The German IVF-Registry (Deutsches IVF-Register, D，I，R) was established in 1982. Its main objective, from the beginning, was to lend transparency and openness to the newly established infertility treatment options. By 1996 electronic data collection was implemented, allowing the online check for data completeness and plausibility as well as ensuring prospectivity. Since 1997, data entry has to be performed electronically. From 1998, participating in the German IVF-Registry has become mandatory by decree of the German Medical Association. By the year 2011, the registry comprised 128 centers, with all 128 submitting their data to D，I，R: 80,934 treatment cycles were reported in 2011; 780,922 datasets are plausible, and 67,935 fulfill prospectivity. 53,076 oocyte retrievals led to an IVF or ICSI treatment, and in 48,166 of these  fresh  cycles, an embryo transfer (ET) was performed. In addition to these  fresh  cycles, 19,228 embryo transfers with cryopreserved thawed pro-nucleus-stage oocytes were recorded. In 2011, the clinical pregnancy rate for IVF is 30.2% and for ICSI 28.3%. Generally we observe that in the data-collection-year the outcome of about 40% of all reported pregnancies is unclear. One year later this figure decreases to about 12.5 15%. From 1997 to 2011, a dramatic reduction of triplets results from the 20 % reduction of the number of embryos transferred. More than one million cycles have been collected since the registry s establishment in 1982 and the births of 171,722 children have been reported to D，I，R since 1997.
