in order to compare the clinical efficacy, safety, success rate and probable complications of rollerball ablation with cutting loop endometrial resection in the treatment of menorrhagia, eighty-three women in reproductive age suffering from menorrhagia who did not respond to medication were treated in a randomized study comparing cutting loop endometrial resection with hysteroscopic rollerball ...
In contrast to the previously published evidence, under ultrasound guidance, individual catheter choice does not statistically significantly affect the clinical pregnancy rate in a modern clinical IVF practice. This may be as a result of decreasing the incidence of difficult transfers and endometrial injury with ET under ultrasound guidance.
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...
There is increasing evidence that prolactin (PRL), a hormone/cytokine, plays a role in breast, prostate, and colorectal cancers via local production or accumulation. Elevated levels of serum PRL in ovarian and endometrial cancers have been reported, indicating a potential role for PRL in endometrial and ovarian carcinogenesis. In this study, we show that serum PRL levels are significantly eleva...
The endometrium has a remarkable capacity for efficient repair; however, factors involved remain undefined. Premenstrual progesterone withdrawal leads to increased prostaglandin (PG) production and local hypoxia. Here we determined human endometrial expression of interleukin-8 (IL-8) and the roles of PGE(2) and hypoxia in its regulation. Endometrial biopsy specimens (n = 51) were collected. End...
BACKGROUND Toll-like receptors (TLRs) play an essential role in the innate immune system by initiating and directing immune response to pathogens. TLRs are expressed in the human endometrium and their regulation might be crucial for the pathogenesis of endometrial diseases. METHODS TLR3 and TLR4 expression was investigated during the menstrual cycle and in postmenopausal endometrium consideri...
The endometrium is a complex, steroid-dependent tissue that undergoes dynamic cyclical remodelling. Transformation of stromal fibroblasts (ESC) into specialised secretory cells (decidualization) is fundamental to the establishment of a receptive endometrial microenvironment which can support and maintain pregnancy. Androgen receptors (AR) are present in ESC; in other tissues local metabolism of...
INTRODUCTION Endometrial biopsy is necessary for diagnosing the reason of abnormal uterine bleeding in perimenopausal women. Currently outpatient endometrial biopsy is used for evaluation of abnormal uterine bleeding which is associated with moderate to severe pain. Using lidocaine is one of the procedures which is used for pain relief while biopsy. This study is aimed at comparing the effect o...
Background: Endometrial receptivity is one of the most important factors in vitro fertilization (IVF) success rate. Many different methods have been suggested to enhance rate implantation IVF\ intracytoplasmic sperm injection (ICSI) cycles. injury, as an intentional trauma aimed at improving fertility results, has gained significant popularity among women seeking pregnancy. This study was condu...
Endometrial cancer is a common female malignancy, affecting approximately 40,000 women per year. Despite the publication of several prospective randomized trials, there continues to be controversy regarding the use of adjuvant radiation therapy in endometrial cancer management. It is clear that most women with early-stage, low-risk disease will do well without adjuvant therapy. Intermediate-ris...
