Metabolomics: the perspective search of methods to overcome infertility

Abstract Nowadays, the reproductive medicine has started to develop precipitously. Nevertheless, 60 to 80 millions of couples worldwide suffer from infertility. The etiology and pathogenesis of many diseases leading to infertility is still causing a lot of debates and needs to be researched further. In 25% of the cases, the cause of infertility may not be identified that forces couples to seek help in auxiliary reproductive technologies. However, even in this case the probability of a positive result makes up no more than 40%. In recent years, scientists' attention became increasingly driven to the so-called omics-disciplines, including metabolomics. Many researchers believe that metabolomics is that science which will give a possibility to improve the quality of diagnosis, will lead to a deeper understanding of the etiology and pathogenesis of diseases that lead to infertility and will improve the quality of the assessment of oocytes and embryos in IVF cycles.
