Optimization of treatment and rehabilitation measures at the preconception stage in patients with reproductive disorders. The effectiveness of the use of natural and preformed physical factors in the preconception preparation of 180 women who underwent medical and rehabilitation measures in the health resort of the Altai Territory - the resort town of Belokurikha (Group 1, 79 patients) and outpatient conditions in the city of Barnaul (Group 2, 101 patients). Comprehensive spa treatment included climatotherapy, a combination of various methods: balneotherapy, peloidtherapy, physiotherapy and a prolonged course of herbal medicine. In patients of the 1st group, who underwent a course of rehabilitation treatment in a sanatorium-resort environment, compared with patients of the 2nd group, early reproductive losses were less common during pregnancy (7.1% and 20.7%, respectively; p=0.04) and more frequent term deliveries occurred (92.8% and 77.2%, respectively; p=0.02). The most significant predictors of the ineffectiveness of preconception preparation were the presence in patients of: chronic cystitis and autoimmune thyroiditis with hypothyroidism; oligomenorrhea at the time of pregnancy planning; aggravated by early reproductive losses and long-term wearing of intrauterine contraception history; burdened heredity for violation of carbohydrate metabolism. Comprehensive preconception preparation in the sanatorium-resort conditions of Belokurikha helps to increase the fertility of patients with reproductive disorders, the trophostimulating effect in the genital organs and the restoration of endometrial reception, which makes it possible to recommend this method for use in clinical practice.
