The thesis investigates the association between Fetuin-B and fertilization rates (number of fertilized eggs) during an ART-Therapy (assisted reproductive technology). More precisely, the author analyses Fetuin-B’s ability to act as a biological prognostic marker. An additional research question of the thesis is, if Fetuin-B is influenced by characteristics such as age, body-mass-index (BMI), nicotine consumption, primary or secondary infertility. Therefore, Fetuin-B levels were measured multiple times from 101 patients that underwent ART-therapy for the first time. ELISA-technique was used for subsequent analysis. The main result is that Fetuin-B significantly increases during successful fertilization (fertilization rate $>25\%),$ whereas Fetuin-B does not increase during unsuccessful fertilization (fertilization rate $<25\%).$ A previous pilot study came to a same result, so these results confirm previous pilot studies and provides further evidence that Fetuin-B can act as a biological prognostic marker for fertilization rates. In addition, this study finds that Fetuin-B is not significantly influenced by individual characteristics. Drawing the conclusion, we observed a significantly increase of Fetuin-B during a successful fertilization (fertilization rate $>25\%)$ which underlines the essential importance of Fetuin-B during the fertilization. In future, it would be interesting to examine the promotor of gene regulation of Fetuin-B and to analyse if there are more association partners of Fetuin-B.}, cin = {537100-2 ; 938420}, ddc = {610}, cid = {$I:(DE-82)537100-2_20140620$}, typ = {PUB:(DE-HGF)11}, doi = {10.18154/RWTH-2024-07681}, url = {https://publications.rwth-aachen.de/record/991096}, }
