In endometrial scratching, endometrium is gently “scratched” using a thin catheter which causes immunological reaction leading to increase implantation rate in women with unexplained recurrent implantation failure. Inducing injury to the lining of the uterus in the cycle before starting ovarian stimulation for IVF can help improve the chances of achieving pregnancy. The new lining which grows a...

Endometriosis, a common cause of pelvic pain and female infertility, depends on the growth of vascularized endometrial tissue at ectopic sites. Endometrial fragments reach the peritoneal cavity during the fertile years: local cues decide whether they yield endometriotic lesions. Macrophages are recruited at sites of hypoxia and tissue stress, where they clear cell debris and heme-iron and gener...

Embryonic implantation is a crucial event for the human reproductive function. Cytokines and paracrine molecules have been proposed as putative local regulators of this process. The leptin or the OB protein has been linked to the reproductive function and inflammatory response. In the present study, we describe for the first time the expression of leptin and leptin receptor (long form) in the s...

BACKGROUND The recruitment of immune cells by chemokines and the regulation of endometrial cell apoptosis are critical aspects of endometriosis biology. Here, we review the local (paracrine) and systemic hormone (endocrine) modulation of these two specific, but highly related phenomena. METHODS We searched Pubmed for items published in English between September 1991 and September 2011 and sel...

Irregular bleeding remains a common reason for the discontinuation of progestin-only contraception. The levonorgestrel releasing intrauterine system (LNG-IUS) has profound morphological effects upon the endometrium. Specific features are gland atrophy and extensive decidual transformation of the stroma. Morphological changes in the endometrium may be associated with perturbation of mechanisms r...

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-...

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 Matrix metalloproteinases (MMPs) and their inhibitors are key-players in extracellular matrix and basement membrane degradation, and are involved in both physiological and malignant processes. The aim of this study was to examine MMP-2, -7 and -9 and TIMP-1 and -2 expression in normal, hyperplastic and malignant endometrium, and their relation to clinical and histological prognostic ...

The present study was designed to investigate the possible properties of the injured brain neurocytes, the expression of heat shock protein70 (HSP70) and Fas protein after acute local ischemia brain injury and local cerebral ischemia-reperfusion injury in rats and to investigate the protecting mechanism of puerarin on the brain neurocytes of rats in acute local ischemia brain injury and local c...
