This article presents the data of multi-year research on the problem of ovarian reserve preservation in cancer patients. The review includes 64 literary sources. The review provides the main methods for ovarian function preservation during the treatment of malignant diseases in patients of reproductive age. Given the increasing number of cancer patients in the group of patients of reproductive age, modern medicine is faced with the task not only to provide effective anticancer treatment, but also to try to preserve ovarian function in order to maintain hormonal levels and fertility. Unfortunately, most cancer treatment methods inhibit ovarian function. Thanks to modern approaches, there are medicinal methods for protecting against ovarian inhibition, which allows to maintain hormonal function and come back to solve reproductive problems after recovering from cancer.

The article presents the algorithms of patient management, depending on the results of smear on oncology and in accordance with the age of the patient.

Physiological loss of ovarian function during the menopausal transition often leads to the development of unfavorable symptoms associated with vulvovaginal atrophy, recurrent urinary tract infections and dyspareunia. Currently, the scientific community is actively discussing the risks and benefits of prescribing menopausal hormone therapy to relieve the consequences of estrogen deficiency. The study of vaginal microbiota in dynamics made it possible to take a deeper look at the development of genitourinary menopausal syndrome and associate several microorganisms with specific undesirable manifestations. The link between recurrent urinary tract infections during menopause and physiological replacement of microbiota by opportunistic flora with the development of unpleasant symptoms resolves doctors to resort to irrational courses of antibiotic therapy. The review is devoted to the generalization of information on microbiological changes in the vagina during perimenopause, the possibilities of choosing the optimal hormone therapy for the correction of symptoms, the use of new promising methods, including management by modulating the vaginal microbiota.

Background. Vitamin D is an essential component that regulates calcium homeostasis and many other cellular functions. Hypovitaminosis D is associated with a risk of osteopenia, obesity, type 1 and type 2 diabetes, malignant neoplasms and immune disorders. Inadequate vitamin D intake during pregnancy increases a risk of pre-eclampsia, preterm birth, low birth weight as well as it has a negative impact on both children’s and adolescents’ health. It is important for the clinician to be known administrating of vitamin D prophylactic and therapeutic regimens according to serum 25(OH)D levels. Aim. To determine causes and effects of vitamin D deficiency and to elaborate ways of their correction. Materials and methods. To write this review a search for domestic and foreign publications in Russian and international search systems (PubMed, eLibrary, etc.) for the last 2-15 years was conducted. The review includes articles from peer-reviewed literature. Results. The article shows that vitamin D has a significant impact on both the cardiovascular, endocrine, digestive, respiratory and other systems functioning and perinatal outcomes that necessitates vitamin D deficiency correction. It provides schemes for effective therapeutic and prophylactic drug doses calculating depending on vitamin D3 blood serum concentration. Conclusion. Preference should be given to cholecalciferol (vitamin D3) due to its better absorption properties and more efficient conversion to active vitamin metabolites (class IIC).
