Perineum injury is an important problem in obstetrics and causes dysfunction of the pelvic floor and prolapse female genital organs. The aim of the work is to reduce the incidence of obstetric injuries by integrated improved method of preparation for childbirth with biological feedback. Materials and research methods: Simple comparative controlled study case control was done in 175 pregnant women in two parallel groups. The main group consisted of 103 patients, trained to control the perineum muscle tone by innovative methodology. The comparison group is made up of 72 pregnant women who have passed standard preparation of a maternity school in a maternity clinic. Results: It was revealed that the perineal muscle tone correlated with high personal and reactive anxiety, which can cause birth injuries. The proposed method reduces the frequency and severity of perineum injuries (15.1 % versus 39.8 %) (OP = 2.6 95 % CI 1.5; 4.5). This makes it possible to recommend to include such method in the mothers school program.

Currently, the concern of endometrial dysfunction is still relevant and is of increasing interest. This is because of new factors have been identified that affect the reproductive function in women. Chronic endometritis and endometriosis mainly affect women of childbearing age, which threatens normal cyclic transformation of the endometrium and tissue receptivity. This consequently affects the main function of the endometrium, which is to ensure successful implantation of the fertilized egg and the development of the chorion and embryo. A detailed understanding of the functioning of the endometrium with a combination of chronic endometritis and endometriosis will improve their diagnosis and treatment.
