Summary

There is increasing evidence that exposure to environmental factors in early development is associated with an increased risk of metabolic and other common diseases. These increased disease risks are likely due to environmental-induced epigenetic changes leading to dysregulation of genes and signaling cascades. The best studied epigenetic modification in this context is DNA methylation. Preliminary studies have already shown that an increased father age or intracytoplasmic sperm injection affects methylation pattern in sperm or umbilical cord blood of children. Unlike sperm, less is known about the methylation of human oocytes and their susceptibility to environmental factors. The aim of this study is to analyze the methylation pattern of immature oocytes of women with decreased fertility. Based on the results of a large number of oocytes from different women, risk assessments could be made for individual factors such as the age of the patient, as well as correlations between the occurrence of changes in gene expression and the unfulfilled desire to have children. In addition, the methylation patterns in sperm from 20 patients are to be examined as reference patterns.
