Obesity is a chronic multifactorial heterogeneous disease characterized by high prevalence, progressive increase in morbidity, high cardiometabolic risk. The prevalence of obesity is increasing from year to year and does not tend to decrease. Up to 60% of women of reproductive age are overweight, and a quarter of them are obese. In addition to cardiovascular pathology, type 2 diabetes, gastrointestinal diseases, oncological processes, obesity can affect the reproductive function of women, reduce fertility and be an independent cause of infertility, as well as reduce the effectiveness of assisted reproductive technology programs. This paper analyzes studies on the problem of reproductive system disorders, the effectiveness and safety of assisted reproductive technology programs in patients with overweight / obesity. The review includes data from foreign and domestic articles in the Pubmed, Elsevier, Cochrane Library, e_library databases published over the past 10 years. As a result of the analyzed publications, it was concluded that the implementation of IVF programs in patients with overweight/obesity presents certain difficulties at each stage of the program: the duration and cost of ovarian stimulation increases, the number and quality of the obtained oocytes and embryos decreases, the displacement of the “implantation window” is more often noted, decreased endometrial receptivity, which together causes a decrease in the pregnancy rate (PR) in this category of patients. It should be noted that in women with visceroabdominal obesity, with more pronounced metabolic abnormalities – dyslipidemia, carbohydrate metabolism disorders, reproductive disorders are expressed to a greater extent than in patients with a more favorable femoral phenotype type of obesity, which requires an individual approach to the treatment of infertility using IVF methods depending on the clinical and etiopathogenetic category of patients.
