The aim of the present study was to evaluate the number of endometrial glandular openings, using previously reported software that provides an objective count, and to assess the variability of this parameter during the luteal phase in a population of women who had no hormonal abnormalities presenting with tubal infertility or male factor infertility. A cross-sectional study was performed compri...

Background It is well documented that ulterasonographic endometrial hyperplasia in polycystic ovary syndrome (PCOS) women is strongly related to pathologic endometrial thickness, but there is no consensus on the relation between serum luteinizing hormone (LH) and either of these factors: pathologic endometrial hyperplasia and body mass index (BMI).��� MaterialsAndMethods An observational cross-...

AIMS The Mirena coil is a levonorgestrel releasing intrauterine device that is in widespread use. This study aims to document the endometrial morphology associated with this device. METHODS Endometrial specimens from 75 women with the Mirena coil were reviewed and the histological features detailed. RESULTS Morphological features found in most of the endometria were decidualisation of strom...

Women using the progestin-only contraceptive Norplant often suffer from unpredictable bouts of breakthrough bleeding, which usually occurs from a thin atrophic endometrium. The role of cellular apoptosis in the endometrial response to Norplant has not been investigated. The aim of the present study was to use immunohistochemistry to produce semi-quantitative scores for expression of the apoptos...

Background. Proliferation and differentiation of the endometrium are regulated by estrogen and progesterone. The enormous regenerative capacity of the endometrium is thought to be based on the activity of adult stem cells. However, information on endocrine regulatory mechanisms in human endometrial stem cells is scarce. In the present study, we investigated the expression of ERα, ERβ, and PR in...

Cytokine-like protein 1 (Cytl1), originally described as a protein expressed in CD34+ cells, was recently identified as a functional secreted protein involved in chondrogenesis and cartilage development. However, our knowledge of Cytl1 is still limited. Here, we determined the Cytl1 expression pattern regulated by ovarian hormones at both the mRNA and protein levels. We found that the endometri...

Endometrial adenocarcinoma (EC) is one of the most frequently diagnosed types of endometrial cancer and is typically a consequence of continuous estrogen receptor stimulation. Erythropoietin-producing hepatocyte receptor B4 (EphB4) and its ligand ephrin-B2 have been reported to be overexpressed in EC cells; however, the function in EC remains unclear. The present study aimed to elucidate the ro...

results endometrial thickness in patients who had 0, 1, 2, 3 and 4 d&c; were 10.00 ± 0.58, 9.83 ± 0.47, 8.90 ± 0.92, 7.42 ± 0.18 and 7.40 ± 0.07, respectively one day before ovulation (spearman’s correlation coefficient = -0.33) and 10.62 ± 0.68, 9.64 ± 0.49, 8.48 ± 0.96, 6.32 ± 0.15 and 6.90 ± 0.04, respectively, 5-7 days after ovulation (spearman’s correlation coefficient = -0.66) estradiol a...

  Background: AUB is a common cause of women’s referring to gynecologists. Although hysteroscopy is known as the gold standard technique for diagnosing the cause of AUB, sonohysterography is less invasive, and it is performed by general gynecologists. The purpose of this study was to evaluate the diagnostic performance of sonohysterography compared to the results of the endometrial biopsy, guid...

The endometrial stromal nodule is a benign tumor composed of differentiated endometrial stromal cells arranged as a well circumscribed nodule with smooth non-invasive margins. They are rare neoplasms, diagnosed in most instances by microscopy. Although nodules are benign in nature, hysterectomy is the treatment of choice to enable evaluation of the tumor margins which are well demarcated in...
