BACKGROUND: De novo somatic copy number aberrations (SCNAs) in eutopic and ectopic endometria are thought to be involved in the pathogenesis of endometriosis. In this study we used, for the first time, high-density single nucleotide polymor…
Female fertility can be affected by diseases or dysfunctions of reproductive tract, neuroendocrine system, and immune system. Reproductive autoimmune failure can be associated with overall activation of immune system or with immune system r…
PROBLEM: Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) is a useful biomarker of infection and inflammation. METHOD OF STUDY: We studied serum and follicular fluid sTREM-1 in infertile patients (N = 110) utilizing enzym…
Expression of survivin, an inhibitor of apoptosis, is increased in endometriotic lesions and probably favors the survival of endometrial fragments in the peritoneal cavity. The aim of this study was to evaluate associations between survivin…
Cytokines are key modulators of the immune system and also contribute to regulation of the ovarian cycle. In this study, Bender MedSystems FlowCytomix technology was used to analyze follicular cytokines (proinflammatory: IL-1β, IL-6, IL-18,…
OBJECTIVE: To investigate whether polymorphisms in genes involved in biosynthesis and signalling of sex steroids influence susceptibility to endometriosis and to infertility associated with it. MATERIALS AND METHODS: Patients with endometr…
OBJECTIVE: To determine plausible associations between endometriosis and vascular endothelial growth factor gene (VEGF -2578 A/C, -1154 G/A, -634 G/C and 936 C/T), also angiotensin I-converting enzyme gene (ACE -240 A/T and 2350 A/G) single…
In this case-control study, we investigated the potential associations of MMP-2 and MMP-9 gene promoter region polymorphisms as well as MMP-2 promoter haplotypes with susceptibility to endometriosis in women of caucasian origin. The results…
PROBLEM: Female infertility patients with diverse etiologies show increased production of autoantibodies. METHOD OF STUDY: Immunoblot analysis of sera from patients with endometriosis and tubal factor infertility (TFI) and mass spectrometr…
Progress has been made towards ascertaining the genetic predictors of ovarian stimulation in IVF. Aromatase cytochrome P450, encoded by the CYP19A1 gene, catalyses a key step in ovarian oestrogen biosynthesis. Hence, the aromatase gene is a…
The outcome of in vitro fertilization (IVF) depends substantially on the effectiveness of controlled ovarian hyperstimulation (COH) induced by administration of follicle-stimulating hormone (FSH). In COH, endogenously produced estrogens ext…
PROBLEM: We have previously demonstrated the presence of naturally occurring antibodies against follicle-stimulating hormone (FSH) in patients with endometriosis and polycystic ovary syndrome (PCOS). Here, we investigated the parameters ass…
PROBLEM: Autoimmune mechanisms are involved in etiology of female infertility, the medical problem frequently treated by in vitro fertilization (IVF). Controlled ovarian hyperstimulation (COH) with supraphysiological levels of sex hormones …
