Introduction: Reproductive health forms the basis of demographic potential and is a necessary prerequisite for population growth, renewal of its quantitative and qualitative composition, which meets socio-demographic needs.

Aim: To study and analyze the dynamics of women’s reproductive health in Ukraine as a factor in population reproduction and to study the features of menstrual disorders in Ukraine in 2010-2019. In women of early reproductive age with hyperproliferative pathology of the endometrium without atypia.

Materials and methods: The peculiarities of menstrual function in patients of early reproductive age with hyperproliferative pathology of the endometrium were studied. We examined 84 patients of the gynecological department of the Sumy Regional Clinical Perinatal Center with a diagnosis of hyperproliferative pathology of the endometrium without atypia, who sought medical help during 2017-2020 for hyperplastic processes of the endometrium in early reproductive age (18 to 34 years).

Results: As a result of the conducted systematic analysis it was established: the higher the prevalence of menstrual disorders, the higher the frequency of diseases of the genitourinary system and some gynecological diseases. This is confirmed by the calculated coefficients of correlation of the prevalence of menstrual disorders with the frequency of diseases of the genitourinary system (r = 0.75, p<0.001), salpingitis (r = 0.63, p<0.001) and endometriosis (r = 0.42, p<0, 05). The assessment of the relative risk of gynecological diseases has shown that the greatest attention needs to be paid to improving the diagnosis of infertility and endometriosis, as well as the prevention and treatment of salpingitis and uterine cancer. 

Conclusions: The highest rates of menstrual disorders were found in women with endometrial hyperplasia without atypia and a combination diffuse hyperplasia with endometrial polyps in contrast to patients with only endometrial polyps. Menstrual irregularities can be considered as a marker and indicator of dysfunction of the genitourinary system and the presence of a hyperproliferative process at the prehospital stage.
