Abstract Study question Are there differences at the molecular level in the most important genes of the mTOR/Akt-pathway in granulosa cells (GCs) of patients with or without endometriosis? Summary answer Our data show increased gene express…

PURPOSE: To characterise the effect of polycystic ovary syndrome (PCOS) on embryo morphokinetics via time-lapse imaging, including absolute time points, relative time intervals, and ratios representing cleavage synchronicity. METHODS: This…

ABSTRACT: To improve clinical outcomes of human medically assisted reproduction, the transfer of multiple embryos is frequently performed. This leads to high rates of multiple pregnancies. In this study we explored if a cohort of patients c…

Abstract Study question What are the metabolome differences between the serum of patients with endometriosis and control subjects? What metabolic traits are characteristic of peritoneal and/or ovarian endometriosis? Summary answer Endometri…

PURPOSE: Endometriosis and infertility are associated with impaired partnership and sexuality of the patients, but also of their male partners. Also, endometriosis is one of the most common causes of infertility, resulting in a large overla…

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…

Abstract Study question How does the gene expression profile of epithelium cells differ between deep infiltrating endometriosis (DIE) and adenomyosis (FA)? Summary answer The gene expression of epithelial cells from DIE reveals a significan…

Zielsetzung 10-15 % aller Frauen im reproduktiven Alter sind von Endometriose betroffen. Dennoch sind die molekularen Mechanismen sowie die Pathogenese nicht vollständig geklärt. Das Ziel der Studie war, die unterschiedlichen Stadien der Er…

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…

Study question: To compare the pregnancy rate in patients submitted to FET (Frozen Embryos Transfer) of cleavage stage embryos (Group 1), or at the blastocyst stage (Group 2). Summary answer: Our data showed that the transfer of frozen blas…

BACKGROUND: The incidence of female infertility has not changed since the early 1990s. Based on new data from basic research on infertility, novel options in the diagnostics and treatment of infertility have emerged, besides in vitro fertil…

OBJECTIVE: To analyze the secondary efficacy and safety outcomes from a recent trial comparing dienogest (DNG) with leuprolide acetate (LA) in women with endometriosis. METHODS: A 24-week, open-label, randomized, multicenter study of DNG v…

Recent developments in reproductive medicine address oocyte morphology, sperm analysis and embryo selection. However, in a subgroup of infertile couples, it is the embryo implantation process that is disrupted. Diagnostic tools to identify …

PURPOSE: To investigate the efficacy and safety of dienogest as a long-term treatment in endometriosis, with follow-up after treatment discontinuation. The study included women with endometriosis, who had previously completed a 12-week, pla…

OBJECTIVE: To investigate the efficacy and safety of oral dienogest 2mg compared with placebo in the treatment of endometriosis-associated pelvic pain (EAPP). STUDY DESIGN: This was a 12-week, randomized, double-blind, placebo-controlled, …

BACKGROUND: Dienogest is a selective progestin that has been investigated in a clinical trial programme for the treatment of endometriosis. The current non-inferiority trial compared the efficacy and safety of dienogest against leuprolide a…

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…
