Introduction: Chronic renal failure is associated with endocrine abnormalities, which in some cases cause polyendocrinopathy responsible for the symptoms and complications. The consequence of secondary hyperparathyroidism is not only bone disease but may be cardiovascular disorders, peripheral nerve damage and impact on the level of sex hormones. The aim of this study was to evaluate the interactions between parathyroid hormone and sexual hormones and the effect of elevated levels of parathyroid hormone secretion on various sexual hormones. The study included 72 patients who were undergoing chronic hemodialysis program 3 times a week at the Clinic for hemodialysis. Patients were divided into two groups according to parathyroid hormone values and child-bearing age. The study is a retrospective-prospective and lasted for 1 year. At the beginning, after 6 months, and at the end of the study were determined the PTH, FSH, LH, progesterone, testosterone, β-estradiol, prolactin. Results: During the study period followed are the values of sexual hormones and PTH in 72 patients of which 41 men and 31 women. Of these 33.3% (24) men were in the reproductive age, and 23.6% (17) were women in the reproductive age. The mean age of patients was 53.2±12.16, and the average duration of hemodialysis was 7.57±4.0. PTH showed a slight tendency to increase 274.45±220.74 pg/dL at baseline, at the end of study 383±313.2 also increased during the study was recorded and the values progesterone. Statistically significant effect of PTH showed the FSH p
