Vitamin D (VD) is a steroid hormone, the effect of which is realized by influencing specific intranuclear VD receptors (VDR). VDR is expressed not only in bone tissue and parathyroid glands, but also in immunocompetent cells, digestive organs, hypothalamic-pituitary system, organs of the reproductive system (ovaries, uterus) and placental tissues.
Based on the mentioned features, VD deficiency can cause various pathologies in the field of gynecology and obstetrics. This fact is of particular interest to obstetricians and gynecologists. There was an association between VD deficiency and the state of women’s reproductive health and the course of pregnancy.
A significant influence of this vitamin from the beginning of intrauterine development to the end of life has been noted, which makes its further study an important area of modern medicine. Achieving an optimal level of VD will reduce the risks of obstetric and perinatal complications and gynecological morbidity.
The study of VD and the impact of its deficiency on women’s health is important for modern medicine; it makes it possible to predict the development of the disease, the nature of its course, the risk of possible complications, which in their turn will improve the patient management and the therapy duration.
