AIM: To investigate the association of CYP2C19 genotypes with endometriosis. METHODS: The study included 100 women who underwent laparotomy or laparoscopy: 50 patients with endometriosis diagnosed with surgery and histopathology, and 50 co…

BACKGROUND: Endometriosis may cause symptoms including chronic pelvic pain and infertility, and increases susceptibility to the development of ovarian cancer. Genomic studies have started to delineate the wide array of mediators involved in…

Endometriosis is a common gynecological disorder of the reproductive age characterised by pelvic pain, dysmenorrhea and infertility. Classic theories have failed to propose a precise pathogenetic mechanism. Recent studies have investigated …

Endometriosis is a common, complex and chronic disease related to ectopic implantation and growth of endometrial tissue that may manifest by pelvic pain, and accounts for over 20% of all cases of infertility in women. Endometriosis may be a…

Membrane proteins of the claudin superfamily are important components of cellular tight and adherens junctions. Although their exact function remains unclear, these proteins may play a role in tissue remodeling, a process which is associate…

Endometriosis is a highly prevalent gynecological condition, where the formation of endometriotic foci is linked with locally increased activity of matrix metalloproteinases (MMPs). In the present study, we tested the hypothesis that raised…

BACKGROUND: There are conflicting data concerning endometriosis and spontaneous abortion (SAB). The aim of the present study was to evaluate if there was any association between endometriosis and SAB. Moreover, we investigated risk factors …

OBJECTIVE: Endometriosis has a wide range of severity but molecular factors associated with variable extension of the disease have not been widely investigated. The present study compares the peritoneal fluid (PF) proteome of 109 women with…

OBJECTIVE: To determine the effect of oral contraceptives containing gestodene on aromatase expression in the endometrium of patients diagnosed with endometriosis. PATIENTS AND METHODS: Endometrial biopsies were taken at the time of laparo…

OBJECTIVE: The aim of the present study was to compare the effect of three different progestins with differing androgenicity on carbohydrate and lipid metabolism in overweight-obese younger postmenopausal women. Additionally, the relationsh…

BACKGROUND: Abnormal uterine bleeding is one of the most common gynecological problems in women aged 15-45 years. The relationship of hyperprolactinemia with reproductive disorders, amenorrhea and irregular menstrual cycles has been known. …

OBJECTIVE: Implantation is a complex phenomenon consisting of the first strong contact between embryo and endometrium. Recent studies have demonstrated that this process is dependent not only on the 'readiness' of the endometrium, but also …

AIMS: To detect aromatase expression in the endometrium of myomatous uteri and to correlate it with the location of the myoma, phase of the menstrual cycle, the presence of menorrhagia and oral contraceptive use. METHOD: Aromatase p450 exp…

OBJECTIVE: We investigated a possible association between endometriosis and polymorphisms in the genes encoding epidermal growth factor (EGF) receptor (EGFR) and EGF in a Japanese population. METHODS: We compared the distribution of the Eg…

An open, prospective, multicenter study was designed to assess the efficacy and safety of dydrogesterone in the post-laparoscopic treatment of endometriosis in Indian patients. Ninety-eight patients suffering from minimal, mild, moderate or…

Endometriosis, a common cause of morbidity, affects 10% of women of reproductive age. In this review we focus on the new developments in pathogenesis, diagnosis and treatment options, reviewing the literature published about this enigmatic …

Endometriosis is defined as the presence of endometrial glands and stroma within extrauterine sites, and it is well known that endometriosis is an estrogen-dependent disease. The defective formation and metabolism of steroid hormones is res…

Lack of expression or a deficiency of 17beta-hydroxysteroid dehydrogenase type 2 (17beta-HSD2), a key enzyme in estradiol inactivation, could be involved in the pathophysiology of endometriosis. The aim of the present study was to evaluate …

BACKGROUND: The metalloproteinases (MMPs) are a family of proteolytic enzymes involved in tissue remodeling and cell migration. Endometrial tissue remodeling proceeds during the menstrual cycle and requires a temporary and spatially balance…

We designed the present study in order to evaluate the eventual role of polymorphisms in the genes encoding cytochrome P450c17alpha (CYP17) and the progesterone receptor (PROGINS) as risk factors for endometriosis development. Eligible case…

n recent years, the research involved to clarify the mechanisms of endometriosis development has opened up new innovative treatments. In fact, not only have new drugs been studied but also new routes of administration for hormones have been…

Oral progestins, without an estrogen component, have been reported to be effective in the treatment of endometriosis, but not adenomyosis or myomas. The mode of action on the target tissue is still a matter of debate. Besides the importance…
