Vascular endothelial growth factor (VEGF) concentrations are elevated in peritoneal fluid of women with endometriosis

Endometriosis is a common chronic gynaecological condition, affecting 5-10% of women of child-bearing age. Its study has been hampered by lack of genetically tractable models. We transplanted steroid-manipulated, menstrual-like endometrium …

The pathophysiology of endometriosis remains unclear but involves a complex interaction between ectopic endometrium and host peritoneal tissues. We hypothesized that disruption of this interaction would suppress endometriotic lesion formati…

In women, a single dose of the antiprogestin mifepristone (RU486) in the secretory phase rapidly renders the endometrium unreceptive and is followed by endometrial breakdown and menstruation within 72 h. This model provides a system to iden…

The mRNAs encoding several Wnt ligands, Frizzled receptors, and Wnt antagonists were detected in human endometrium, including SFRP1; the levels of SFRP1 mRNA were higher in the proliferative phase of the menstrual cycle and increased in end…

Since retrograde menstruation is considered a key event in the aetiology of endometriosis, this study sought to determine whether the menstrual effluent of women with this condition is different from that of those with a normal pelvis. As t…

BACKGROUND: Heavy regular menstrual periods (menorrhagia) are an important cause of ill health in women and remain the leading indication for hysterectomy. Abnormalities of the endometrial blood vessels are among the possible causes of this…

Interleukin-1beta (IL-1b) is an important immune regulatory factor that in human endometrium plays a role in both menstruation and implantation in the event of pregnancy. It promotes inflammatory-like processes and also stimulates tissue re…

BACKGROUND: Women with endometriosis have elevated levels of cyclooxygenase-2 (COX-2) in peritoneal macrophages and endometriotic tissue. Inhibition of COX-2 has been shown to reduce inflammation, angiogenesis and cellular proliferation. It…

BACKGROUND: Angiogenesis and vascular remodeling play critical roles in the cyclical growth and regression of endometrium. They also appear to play roles in the pathogenesis of endometriosis. METHODS AND RESULTS: Supernatants were collected…

Implantation in humans is a complex process that is temporally and spatially restricted. Over the past decade, using a one-by-one approach, several genes and gene products that may participate in this process have been identified in secreto…

Endometriosis is a disease in which the lining of the uterus (endometrium), shed at the time of menstruation, becomes established at sites such as the peritoneum and ovaries. These explants develop a rich blood supply that enables them to s…

Objective: We aimed to identify genes in normal human eutopic endometrium which respond to ovarian steroid hormone stimulation. We identify factors of possible interest in the pathogenesis of endometriosis.Design: The growth of ectopic endo…

Angiogenesis is essential for endometrial growth and repair, and disruption of this process may lead to common disorders of women, including menorrhagia and endometriosis. In pregnancy, failure of the endometrial spiral arterioles to underg…

A crucial stage in pregnancy is the implantation of the embryo into the endometrium. The endometrium, which is situated in the lining of the uterus, is a complex structure consisting of a single epithelial layer overlying a mesenchymal stro…

Abnormal endometrial bleeding continues to be a significant problem for women using long-acting gestagens and not only reduces the use of these agents, thus restricting the options available to women, but also reduces the quality of their l…

One common side-effect of contraceptive use is that it often leads to disrupted endometrial bleeding patterns. This may be due to changes in endothelial density and vessel integrity. To investigate whether the level of endometrial immunorea…

Endometrial growth and repair after menstruation are associated with profound angiogenesis. Abnormalities in these processes result in excessive or unpredictable bleeding patterns and are common in many women. It is therefore important to u…

BACKGROUND: Endometriosis is a common gynaecological condition that frequently presents with the symptom of pain. The precise pathogenesis (mode of development) of endometriosis is unclear but it is evident that endometriosis arises by the …

OBJECTIVE: To determine whether an educational package could influence the management of menorrhagia, increase the appropriateness of choice of non-hormonal treatment, and reduce referral rates from primary to secondary care. DESIGN: Random…

Contraceptive use often leads to disrupted endometrial bleeding patterns in women. In this study, two different contraceptive regimes (Mircette, a monophasic oral contraceptive and Implanon, a long-acting gestagen) were used and their effec…

Endometriosis remains a significant cause of pain and ill health for women and is a significant factor in reducing quality of life for women. The ability of desquamated endometrium to attach and implant within the peritoneal cavity is depen…

Endometriosis is characterized by an increase in the number, activation and secretory activity of peritoneal fluid macrophages. Factors regulating the activation of these cells may be important in the pathophysiology of this disease. In thi…
