Introduction: The work has been dedicated the study of pituitary hormone concentration in the blood of women with endometriosis-associated infertility on 2-3 days of the menstrual cycle and the day of the puncture of ovarian stimulation superovulation in the cycle. The aim of our study was to examine the concentration of pituitary hormones in the blood of women with endometriosis associated with infertility. Materials and methods: For the purpose of the research we have conducted a special study of protein (lutropin - LH, folitropin -FSH) hormones level in the blood plasma of women with endometriosis associated with infertility, which formed the main group of 20 people. Similar studies of protein hormones level were performed in the control group, which made somatically healthy women of reproductive function preserved, whose age corresponded to the age of patients of the main group. The value of p (authenticity difference) was determined by Student's table-Fischer. Differences between contrasting averages were considered significant at p <0.05. Results and conclusions: Analized the results of our research stated that women with endometriosis associated with infertility 2-3 days of the menstrual cycle endocrine function of gonadotropocites anterior pituitary did not differ from that of the control group. This fact appeared to have an additional criteria for the formation of a main group. In patients with endometriosis associated with infertility found significant violation of rhythm and secretion of blood gonadotropin hormones that are proportionate to the degree of severity of the disease.
