BACKGROUND: Endometriosis is a gynecological condition which often causes chronic or recurrent pelvic pain (CPP). The disease can thereby impose a significant burden on affected individuals and their romantic relationships. Existing researc…

BACKGROUND: Endometriosis is a frequent disease in women of reproductive age in which the endometrium occurs outside the uterine cavity. Multimodal treatment approaches are necessary due to loss of quality of life and the chronic nature of …

Abstract Backround Endometriosis is a frequent disease in women of reproductive age in which the endometrium occurs outside the uterine cavity. Multimodal treatment approaches are necessary due to loss of quality of live and the chronic n…

BACKGROUND: The pathogenesis of deep infiltrating endometriosis (DIE) is poorly understood. It is considered a benign disease but has histologic features of malignancy, such as local invasion or gene mutations. Moreover, it is not clear whe…

PURPOSE: This study attempted at identifying the main parameters influencing the outcome of frozen embryo transfers. METHODS: This is a single-center retrospective cohort study of 830 frozen-embryo-transfer cycles performed at a German uni…

Abstract Purpose Endometriosis and infertility are associated with impaired partnership and sexuality of the patients, but also of their male partners. The aim of this study was to determine the association of different predictors of partne…

The differentiation of endometrial stromal cells, named decidualization, is essential for the proper formation of the materno-fetal interphase. One important feature of decidualization is the increased glucose consumption and its utilizatio…

BACKGROUND: Endometriosis is often associated with severe dysmenorrhea, pelvic pain and dyspareunia and has a high impact on daily life as well as sexuality. Quality of partnership positively influences the course of various diseases and ab…

Endometriosis and Menopause Abstract. Endometriosis is supposed to affect only women in their reproductive years, but endometriotic lesions can reactivate in menopause and cause significant complaints in these patients. Altered needs and co…

In order to improve ART outcome, non-invasive embryo assessment is gaining more and more attention. Therefore, the aim of this study is to determine the consecutive implantation potential via the secretome between blastocysts with or withou…

PURPOSE: Endometriosis (EM) is a common gynecological disease affecting 10-15% of women of reproductive age. However, molecular mechanisms and pathogenesis are still not completely understood. Furthermore, due to the absence of a reliable c…

Background: The impact of controlled ovarian stimulation (COS) during medically assisted reproduction (MAR) on human embryogenesis is still unclear. Therefore, we investigated if early embryonic development is affected by the type of gonado…

During the menstrual cycle, the endometrium undergoes cyclic changes of cellular proliferation, differentiation, and death, an essential preparation of the endometrium for its interaction with the implanting embryo. In particular, the diffe…

PURPOSE: To study if ovarian response is affected by the type of disease if fertility preservation is required. METHODS: A registry of the trinational fertility preservation network FertiPROTEKT including 992 patients aged 18-40 years unde…

INTRODUCTION: Time-lapse technology allows almost continuous noninvasive assessment of embryonic development. It was shown previously that relative kinetics defining cleavage synchronicity are better predictors of blastocyst quality than ab…

BackgroundFertility-preserving measures for women are increasingly being performed for non-medical reasons in Germany. This is now a controversial matter.MethodsThe authors searched the PubMed database for pertinent publications on the basi…

BACKGROUND: The pathophysiology of recurrent pregnancy loss (RPL) is still unknown in 50% of the cases. Herein we measure the expression of beta3 integrin subunit, a well-known implantation marker, in women with or without RPL and correlate…

The human oviduct serves as a conduit for spermatozoa in the peri-ovulatory phase and nurtures and facilitates transport of the developing embryo for nidation during the luteal phase. Interactions between the embryo and oviductal epithelial…

BACKGROUND: Reproductive failure, determined as recurrent spontaneous abortions (RSA) or recurrent implantation failure (RIF) in women is not well understood. Several factors, including embryo quality, and cellular and molecular changes in …

So far, implantation is a poorly understood process, which involves several paradoxical cell-biological mechanisms. First, 50% of the embryo is paternal and immunologically foreign material, and second, both the endometrium and embryo are c…

Endometriosis is clinically associated with pelvic pain and infertility, with implantation failure strongly suggested as an underlying cause for the observed infertility. Eutopic endometrium of women with endometriosis provides a unique exp…
