BACKGROUND Success rates of assisted reproductive techniques (ART) are approximately 30%, with the most important limiting factor being embryo implantation. Mechanical endometrial injury, also called 'scratching', has been proposed to positively affect the chance of implantation after embryo transfer, but the currently available evidence is not yet conclusive. The primary aim of this study is t...
background: implantation failure is one of the most important factors limiting success in ivf treatment. the majority of trials have demonstrated favorable effect of endometrial injury on implantation success rate especially in women with recurrent implantation failure, while some studies failed to detect any benefit. objective: the purpose of our trial was to explore whether endometrial injury...
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-...
Background: Ultrasound is preferred as first imaging modality in the study of the female pelvis. In this article, we have tried to mention 8 points that each midwife or nurse needs to know for planning the time of sonography and analysis of findings. Results: During the menstrual cycle, all pelvic organs are influenced by cyclic changes. Thus, pathologic conditions of pelvis need to be well ass...
Interleukin-1 (IL-1) is a pleiotropic cytokine implicated in endometrial and embryonic physiology. Our objective was to determine the presence of IL-1 in the endometrium, oviduct, and uterine fluid of cows at days 0, 7, and 14 of the estrous cycle. Immunoreactive IL-1beta was identified in endometrial and oviductal tissues throughout the estrous cycle by immunohistochemistry. Both glandular and...
OBJECTIVES Molecular changes observed in endometrium with respect to menstrual cycle changes seem to be crucial for the reproductive function. Accumulation of cytotoxic cells increases the exposure of endometrial cells to apoptosis. Protection against apoptosis may be reached by endometrial cells by self molecular regulation. Metallothionein was suggested to participate in this process. The aim...
Urocortin 2 and urocortin 3 in endometriosis: evidence for a possible role in inflammatory response.
Urocortin 2 (Ucn 2) and urocortin 3 (Ucn 3) are neuropeptides expressed by human endometrium. This study evaluated (i) the expression of Ucn 2 and Ucn 3 mRNA in endometriotic lesions and in endometrium of women with endometriosis; (ii) the effect of Ucn 2 and Ucn 3 on cytokines secretion from cultured endometrial stromal cells. Endometriotic tissue was collected from endometrioma (n=39); endome...
We present the case of a 44-year-old nulliparous woman who experienced irregular menstrual cycles for about 10 years and developed both pituitary prolactinoma and endometrioid endometrial carcinoma. In premenopausal women, hyperprolactinemia causes hypogonadism by inhibiting secretion of gonadotropin-releasing hormone and thus suppressing luteinizing hormone levels, which can cause menstrual di...
BACKGROUND The purpose of this study was to investigate the endometrial safety of an oral contraceptive containing estradiol valerate/dienogest (E(2)V/DNG) administered as an estrogen step-down and progestogen step-up regimen in women of reproductive age (18-50 years), using histological assessment of endometrial biopsy samples. METHODS Endometrial biopsies were taken in a subset of healthy w...
26 27 Background: The adjunction of exogenous hormones for controlled ovarian stimulation 28 (COS) may alter endometrial receptiveness. In order to identify the genes mis-regulated under 29 COS, we compared the endometrium gene expression profiles, from the same patients, in a 30 natural cycle and in a subsequent COS cycle. Methods: For the same normal-responder 31 patients (n=21), endometrial ...
