Infertility is a common condition and clinical causes are equally prevalent in both men and women. However, the underlying mechanisms of infertility remain largely unclear, often impeding specific diagnoses and personalised, evidence-based treatments. Reproduction.MS pools the expertise of researchers from the University of Münster, the University Hospital Münster, and the Max Planck Institute for Molecular Biomedicine in this field. Additionally, Reproduction.MS coordinates a dynamic network of interdisciplinary collaborative research funded by the DFG, BMBF, and internal sources, bridging the gap between science and clinic. The local facilities and the breadth of reproductive research enable top-level research in both basic and clinical research, as well as in the diagnosis and treatment of infertility. Our overarching goal is to swiftly translate research findings into benefits for patients and, ultimately, for society.
