Angiogenesis is the development of new blood vessels from pre-existing ones. It is a complex multifaceted process that is essential for the adequate functioning of human organisms. The investigation of angiogenesis is conducted using variou…

Autoimmune thyroid disease (AITD) is one of the most common endocrinopathies and is more prevalent in women. It becomes evident that the circulating antithyroid antibodies that often follow AITD have effects on many tissues, including ovari…

Objective of the Review: A review the results of published scientific research on the special characteristics of endometrium in women with recurrent implantation failures. Key points. Endometrial receptivity and the importance of its analys…

During pregnancy, uterine NK cells interact with trophoblast cells. In addition to contact interactions, uterine NK cells are influenced by cytokines, which are secreted by the cells of the decidua microenvironment. Cytokines can affect the…

BACKGROUND: The uterine junctional zone is the inner part of the myometrium. Dysfunction of the zone may underlie the pathogenesis of adenomyosis and its clinical manifestations, while biometric characteristics of the zone are currently con…

OBJECTIVE: The present study was to find a pathogenic evidence for dopamine agonist application in patients with endometriosis associated pain syndrome. PATIENTS AND TECHNIQUE: The study involved 227 patients of reproductive age with histol…

ЦЕЛЬ ИССЛЕДОВАНИЯ Изучение морфологических особенностей эндометрия при гиперплазии без атипии у женщин с бесплодием, ассоциированным с наружным генитальным эндометриозом и миомой матки. МАТЕРИАЛ И МЕТОДЫ Комплексное морфологическое исследов…

Hypothesis/aims of study. Overcoming infertility and miscarriage in adenomyosis is a complex practical problem in obstetrics and gynecology. It is likely that one of the signs of the disease is a thickening of the transitional zone between …

Background. Pelvic inflammatory disease (PID), including chronic endometritis (CE), is a factor leading to endometrial receptivity disorder and in vitro fertilization (IVF) failures. The role of microorganisms in colonizing the endometrium,…

BACKGROUND: Severe forms of genital endometriosis are known to be associated with infertility and its subsequent treatment failure. Both gonadotropin-releasing hormone analogs (a-GnRH) and dienogest have been suggested as additional hormone…

Background. There is no clear idea of what factors determine the characteristics of pain in endometriosis. Scientific data on the relationship between morphological and functional features of heterotopic tissue, and the intensity of the pai…

Abstracts Background: Implantation failure of in vitro fertilization (IVF) cycles is recognized as one of key problems in contemporary reproductive medicine. Implantation itself is a multifactorial process and one can hardly expect to find …

We report three cases of effective management of infertility in women with a history of repeated unsuccessful IVF attempts, who have developed antibodies to hCG. A novel approach to conservative treatment of immunologic reproductive failure…

Background. A local inflammatory reaction in the endometrium caused by viral infection and associated with external genital endometriosis (EGE) can affect the implantation properties of endometrium and be one of the causes of infertility. T…

There is a violation of the secretory transformation of the endometrium during the implantation window in patients with the infertility associated with inflammatory diseases of the small pelvic organs, against the background of a high incid…
