Background: Endometriosis, a gyncological disorder,benign and common cause of infertility, is defined as the presence of endometrial glands and stroma at ectopic locations outside the uterine cavity. Clinical observations have led to the assessment that endometriosis is an invasive disease. Abnormal expression of adhesion molecules such as cadherins is likely to be an important determinant of l...

BACKGROUND Endometrium is a unique tissue that is prepared for implantation of blastocyst during each menstrual cycle. In humans, if implantation does not occur or fails, endometrium is shed. METHODS AND RESULTS We identified ebaf/lefty, as a key cytokine, highly expressed in human endometrium during the non-receptive phase of tissue remodelling. Lefty was increased in the endometria of a num...

BACKGROUND The levonorgestrel intrauterine system (LNG-IUS) is a contraceptive device that is used for treatment of menorrhagia. The system induces inter-menstrual bleeding within the first few months after insertion. We hypothesized that this bleeding might be associated with a change in vascular development. METHODS A randomized, controlled study was undertaken on 48 women. RESULTS Hyster...

A series of 191 endometrial biopsy procedures were performed on Indonesian women who had received between 3 and 12 months exposure to Norplant. In all, 87 biopsy procedures were attempted with a microhysteroscope using biopsy forceps, and 104 procedures were attempted with either Pipelle or Karman suction curettes. Regardless of the biopsy method, diagnosable endometrium was obtained in only ap...

Introduction Postmenopausal bleeding (PMB) is the most common symptom of the endometrium. Cervical cancer must also not be forgotten, especially in women with a thin endometrium. Therefore, all women presenting with PMB should undergo evaluation with transvaginal ultrasound to estimate the risk of endometrial cancer, and speculum examination/cervical cytology to rule out cervical pathology. Man...

Endometriosis is one of the most common gynaecological disorders, but its aetiology and pathogenesis remain obscure. The refluxed menstrual debris in women with endometriosis may be more prone to implantation, invasion and growth in the peritoneum or ovary through the actions of extracellular proteolysis and angiogenesis. It has been hypothesized that the endometrium from women with endometrios...

The aim of this study was to investigate the effect of surgical intervention on the expression of leukemia inhibitory factor (LIF) and L-selectin ligand in the endometrium of patients with hydrosalpinx during the implantation window. A total of 60 patients with hydrosalpinx and 30 patients with tubal obstruction were recruited, and immunohistochemistry was performed to detect the expression of ...

BACKGROUND Various endometrial abnormalities have been associated with luteal phase deficiency: a significant dyssynchrony in the maturation of the glandular epithelium and the stroma and a prevalence of out-of-phase endometrial biopsy specimens. Out-of phase endometrium is a controversial disorder related to failed implantation, infertility and early pregnancy loss. Given that the regulation o...

We investigated the distribution of endometrial lymphatic vessels and expression of forkhead box C2 (FOXC2) in normal endometrium during menstrual cycle and in endometrial adenocarcinoma. Full-thickness uterine samples and endometrial adenocarcinoma samples were collected for immunohistochemical analysis using D2-40 and FOXC2 mouse monoclonal antibodies. The lymphatic vessel density (LVD) of th...

BACKGROUND Endometriosis is a common gynaecological disorder characterized by the presence of endometrial tissue outside of the uterus. The fragments in normal menstruation are composed of necrotic and living cells, which do not survive in ectopic locations because of programmed cell death. The aim of this study was to evaluate if the balance between cell proliferation and apoptosis is changed ...
