Ovarian reserve is the basis of female fertility. The main markers of ovarian reserve are the level of anti-Mullerian hormone and the number of antral follicles. In addition to the natural age-related loss of follicles, many women experience a premature diminished ovarian reserve associated with a number of factors. This can be caused by both various diseases and environmental factors, lifestyle, and social aspects.The aim of this review was to examine the influence of external factors on the ovarian reserve and women fertility. A systematic analysis of data from modern scientific literature, domestic and foreign sources was carried out. The search involved such resources as PubMed, MEDLINE, Science Direct, eLibrary, Scopus, Cyberleninka. A detailed analysis of the influence of environmental pollution, lifestyle (sleep, nutrition, physical activity), previous surgeries, bad habits, obesity, psychological and social factors on the ovarian reserve and reproductive function of women was carried out. Significantly diminished ovarian reserve was noted with low sleep quality, excessive physical activity, and an unbalanced diet poor with animal proteins. Regular consumption of alcohol, smoking and exposure to certain chemical environmental pollutants cause premature follicle apoptosis and the onset of menopause. Circadian dysrhythmia, chronic stress and obesity can lead to the ovarian menstrual cycle disorders and the development of infertility in women. Previous parovarium surgeries are a significant risk factor for diminished ovarian reserve. Further population-based studies are needed to determine the precise mechanisms of influence of various factors on female fertility.
