[Endocrine genesis of the development of menstrual cycle disorders in reproductive age].

In recent decades, the Russian government has been committed to improving the country's demographic situation. Therefore, obstetricians and gynecologists pay special attention to women of reproductive age, whose reproductive system disorders can lead to infertility and the inability to conceive. Menstrual cycle disorders (MCDs) are a manifestation of various pathological conditions associated not only with disorders of the female reproductive system but also with general systemic and endocrine diseases. Since the 1980s, the incidence of MCDs has increased more than sevenfold. MCDs are characterized by changes in the cycle frequency, duration, and volume of menstrual blood loss. An obstetrician/gynecologist who initially consults a woman of reproductive age with MCDs should not only develop an examination plan for the patient, but most importantly, collect a detailed medical history, including a description of her physical condition, sports history, dietary habits, medication intake, including vitamins and dietary supplements, and analyze the relationship between MCDs and epigenetic factors in the woman's life. The incidence of NMC in the presence of an endocrine disease is up to 35% and requires referral of the patient to an endocrinologist to compensate for the endocrinopathy.
