Workshop report: evaluation of genetic and epigenetic risks associated with assisted reproductive technologies and infertility.
In January 2005, the Assisted Reproductive Technologies (ART) Workshop: Evaluation of Genetic and Epigenetic Risks Associated with Assisted Reproductive Technologies and Infertility was convened to evaluate current data on genetic and epigenetic risks to offspring conceived after a period of infertility and/or via ARTs. Formal presentations and workshop breakout groups reviewed the information from a broad range of disciplines and discussed issues regarding study design, molecular approaches, animal model systems, clinical outcomes, and ethical, legal, and psychosocial issues. The key recommendations of the workshop are that: [1] ART research and education should flow from clinical and basic science studies of the fundamental biology of early mammalian embryonic development, with a focus on how infertility and/or ART might disrupt such processes; [2] such research should include the emerging area of epigenetics and its potential role in reproductive health outcomes; [3] methods for the standardization of data collection and for handling and analysis should be employed, including precise definitions of obstetric and perinatal terminology; [4] much greater awareness and ongoing evaluation of the psychosocial impact of ART and ART research on women, their partners, and their offspring are required; and [5] effective methods of knowledge transfer need to be developed and delivered to healthcare providers and to the general public regarding reproductive planning, infertility, and ART, including the potential risks associated with each.
