The presence of a thin endometrium has an important role in allowing the best conditions for hysteroscopic surgery. Here, we explored the efficacy of a 14-day administration of nomegestrol acetate, a progestogen with high progestogen potency effects, in rapid endometrial preparation to operative hysteroscopy. A total of 86 fertile women selected for operative hysteroscopy received for 14 days e...

Freezed embryo transfer increases the cumulative pregnancy rate, reduces costs, is relatively simple to undertake and can be accomplished in a shorter time period compared to repeated Fresh cycle. There are different protocols for endometrial preparation. Although frozen embryo replacement cycles, have been used for several years, there is no agreement about the optimal way to prepare the endom...

UNLABELLED The purpose of the study was to assess physiologic endometrial (18)F-FDG uptake during the 4 phases of the menstrual cycle and to differentiate between physiologic and malignant endometrial uptake. METHODS Endometrial (18)F-FDG uptake, expressed as standardized uptake value (SUV), was measured on PET/CT images of 285 consecutive female patients, of whom 246 (112 premenopausal and 1...

PURPOSE HDAC inhibitors (HDACIs) have been shown to inhibit cancer cell proliferation, stimulate apoptosis, and induce cell cycle arrest. Our purpose was to investigate the antiproliferative effects of the HDACIs [suberoyl anilide bishydroxamine, valproic acid (VPA), trichostatin A, and sodium butyrate] against six endometrial cancer cell lines. EXPERIMENTAL DESIGN Endometrial cancer cells we...

Title: Colony Stimulating Factor-1 and Leukemia Inhibitor Factor expression from current-cycle cannula isolated endometrial cells are associated with increased endometrial receptivity and pregnancy Authors: Felipe Camargo-Díaz ([email protected]) Valeria García ([email protected]) Azucena Ocampo-Bárcenas ([email protected]) Humberto González-Marquez ([email protected])...

Endometrial sonographic and color doppler features can be used to predict the occurrence of pregnancy in natural or stimulated cycles. Implantation will usually only take place if the endometrium has reach a certain stage of vascularisation and development. The aim of this study was to evaluate endometrial development -- endometrial thickness and reflectivity , subendometrial, endometrial and u...

The endometrium is a highly dynamic tissue empowered with the capacity to undergo cyclic dramatic changes in response to ovarian steroid hormones, ultimately aiming to create a window of receptivity for blastocyst implantation. Intensive research has been performed to understand and establish morphological and molecular correlates of embryo implantation. However, it still remains a biological m...

BACKGROUND The role for endometrial secretion of cytokines during the establishment of pregnancy in a number of mammals is well established. The current study determined endometrial expression of caspase 1 (CASP1) and interleukin-18 (IL18) during the estrous cycle and early pregnancy, and following early estrogen administration, which induces conceptus loss during early development in pigs. M...

A delicate balance between estrogen and progestagen signaling underlies proper functioning of the female reproductive tract and, in particular, the monthly re- and degenerative phases characteristic of the menstrual cycle. Here, we propose that the canonical Wnt/β-catenin signaling pathway may underlie this finely tuned hormonal equilibrium in endometrial homeostasis and, upon its constitutive ...

The human endometrium prepares for implantation of the blastocyst by reorganization of its whole cellular network. Endometrial stroma cells change their phenotype starting around the 23rd day of the menstrual cycle. These predecidual stroma cells first appear next to spiral arteries, and after implantation these cells further differentiate into decidual stroma cells. The phenotypical changes in...
