Reindeer husbandry is the leading branch of agriculture for the regions of the Far North. Reindeer (Rangifer tarandus) remains poorly studied from the point of view of genetics and reproduction, which hinders the intensification of development of the industry. Research is being actively conduct in the field of genetics of the productive qualities of reindeer, but the formation and functioning of its reproductive system has been little study. Hormonal regulation of the reproductive process and the formation of hormonal status at key stages of the reproductive cycle is a significant aspect of animal reproduction. Reindeer are characterized by a pronounced seasonality of reproduction, and the study of hormonal regulation of the reproductive cycle is the main aspect of the further use of assisted reproductive technologies. The work is devoted to the analysis of the level of anti-Mullerian hormone in females during the breeding season. The studies were carried out on reindeer farms of the MAU “Directorate of the Territory of Traditional Natural Resources Management of Soyots”, Buryatia, (female, n=29). The dependence of the concentration of anti-Müllerian hormone (AMH), which is a generally accepted indicator of the female ovarian reserve, on the concentration of sex hormones (progesterone, estradiol, testosterone and luteinizing hormone) in the blood serum of females was study. Hormone levels were determined by enzyme immunoassay. A higher content of sex hormones - testosterone, estradiol, progesterone and luteinizing hormone was revealed in the group of women with an AMH concentration of >1 ng/ml than in the group of women with an AMH concentration of <1 ng/ml. The significance of the differences in progesterone was p<0.05, and in estradiol – p<0.001. A low concentration of AMH (<1 ng/ml), characterizing a reduced ovarian reserve of female reindeer, corresponds to a reduced concentration of sex hormones that support reproductive function, and, conversely, a high concentration of AMH (>1 ng/ml), and, accordingly, a high ovarian reserve the reserve corresponds to an increased concentration of sex hormones - testosterone, estradiol, progesterone and luteinizing hormone.
