BACKGROUND: The Fallopian tube undergoes well-recognized changes during the ovarian cycle. Ciliary beat frequency (CBF) increases during the secretory phase of the cycle. The stimulus is unknown, although CBF is known to be hormone responsi…

BACKGROUND: Asoprisnil (J867) is a novel selective progesterone receptor modulator (SPRM) that exhibits partial agonist and antagonist activities and tissue selective effects. This double-blind, dose-escalation study was conducted to evalua…

BACKGROUND: We questioned whether a laparoscopy should be performed after a normal hysterosalpingography before starting intrauterine inseminations (IUI) in order to detect further pelvic pathology and whether a postponed procedure after si…

BACKGROUND: Vascular endothelial growth factor (VEGF), a major mediator of angiogenesis and vascular permeability, is known to play a key role in the pathophysiology of endometriosis. METHODS AND RESULTS: The single nucleotide polymorphism…

BACKGROUND: A key factor in the pathogenesis of endometriosis is the endometrial-peritoneal adhesion. To study the pathogenesis of endometriosis, a quantitative in vitro assay (QIVA) was developed to measure in vitro adhesion between human …

BACKGROUND: The aim of this study was to evaluate the diagnostic significance of CA-125 for endometriosis without ovarian endometriomas. METHODS: Preoperative serum CA-125 levels were measured in 775 consecutive women diagnosed by laparosc…

BACKGROUND: Vascular endothelial growth factor (VEGF) is known to play a pivotal role in the development of endometriosis. This study was performed to investigate whether the VEGF gene 5'-untranslated region polymorphism is associated with …

BACKGROUND: We previously reported that the level of interleukin (IL)-6 is increased in the peritoneal fluid of women with endometriosis. This study was undertaken to assess the effects of IL-6 and soluble IL-6 receptor (sIL-6R) on in vitro…

BACKGROUND: Recent studies have demonstrated the overexpression of cyclooxygenase-2 (COX-2) in endometriosis. The aim of this study was to investigate the expression of COX-2 in different anatomical sites of endometriosis and its associatio…

BACKGROUND: Endometriosis is a common gynaecological problem of uncertain aetiology. It affects primarily young, reproductive-aged women and can result in chronic pelvic pain and infertility. Current approved therapies have significant side…

BACKGROUND: Pelvic endometriotic lesions are often laden with hemosiderin. In order to investigate the potential source of such iron deposits, we examined whether the seric and erythrocyte fractions of menstrual effluent might influence the…

BACKGROUND: In a prospective study we measured circulating levels of vasoactive factors and their soluble receptors in women undergoing controlled ovarian stimulation (COS) for IVF who were at risk for ovarian hyperstimulation syndrome (OHS…

BACKGROUND: Endometriosis is an important clinical situation associated with subfertility. It would be very useful to identify patients at increased risk for endometriosis prior to laparoscopy. In the present study, we evaluate the demograp…

BACKGROUND: Failure of apoptosis of refluxed endometrial cells within the peritoneal cavity is a possible etiologic factor for development of endometriosis. Osteoprotegerin (OPG) is a survival factor that exerts its effect by binding to tum…

BACKGROUND: Increased expression of killer cell inhibitory receptors (KIRs) has been found on natural killer (NK) cells in peritoneal fluid in women with endometriosis. In this study, we tried to measure the expression of KIRs on NK and T c…

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) in IVF/ICSI cycles may occur either as an early (early onset) or a late pattern (late onset). This observational study was designed to identify whether the onset pattern of OHSS is associ…

BACKGROUND: The interaction between spermatozoa and the epithelium of the isthmic region of the uterine tube is thought to be an important part of the mechanisms of sperm transport to the site of fertilization and in preparing them for fert…

BACKGROUND: Hormonally active environmental agents have recently been associated with the development of endometriosis. METHODS: We undertook a study to assess the relationship between endometriosis, an estrogen-dependent gynaecological di…

BACKGROUND: For the implantation of endometrium in ectopic locations, remodelling of the extracellular matrix (ECM) is necessary. Many studies have shown an increased expression of various proteases in the ectopic endometrium of women with …

BACKGROUND: Although the etiology of endometriosis is not well understood, chemokines and their receptors are believed to play a role in its pathogenesis. Therefore, we aimed to investigate the expression and localization of interleukin-8 (…

BACKGROUND: Endometriosis occurs in several non-human primate species that have menstrual cycles. This study investigated the prevalence and familial aggregation of endometriosis in one of those species, the rhesus macaque. METHODS: Betwee…

BACKGROUND: Pituitary suppression by depot GnRH agonist may be excessive for ovarian stimulation in assisted reproduction technology. This study compares the efficacy of standard and half-dose depot triptorelin in a long protocol. METHODS:…

BACKGROUND: The success of IVF treatment is dependent upon embryo quality and coordinated growth and differentiation of the endometrium. Aromatase P450 expression in the human endometrium is thought to be restricted to women with proliferat…

BACKGROUND: Our aim is to assess the prevalence and characteristics of headache in patients with endometriosis compared with women without this disease. METHODS: One hundred and thirty-three women with histologically proven endometriosis a…
