Endometriomas occur in a subset of patients with endometriosis. Treatment is surgical, particularly for larger sized endometriomas. The presence of an endometrioma in the ovary and/or its treatment may diminish ovarian reserve and negativel…
Endometriosis is an estrogen-dependent disorder where endometrial tissue forms lesions outside the uterus. Endometriosis affects an estimated 10% of women in the reproductive-age group, rising to 30% to 50% in patients with infertility and/…
Previous studies examining gene expression profiles in normal endometrium and endometriotic lesions have used RNA extracted from whole tissue samples. Results from these studies can be difficult to interpret as they reflect expression avera…
Angiogenesis, arteriogenesis or vessel maturation, and lymphangiogenesis comprise a continuum of vascular development, with overlap and interaction between the mechanisms by which they are controlled. These processes are of clinical interes…
The objective of this study is to examine the localization and expression of FOXP1 in human endometrium during the menstrual cycle and in endometriotic lesions and endometrial adenocarcinoma. FOXP1 protein expression was analyzed by immunoh…
BACKGROUND: Despite the fact that uterine fibroids are the most common benign tumors in women, their etiology is poorly understood. We have previously shown that multiple members of the retinoic acid (RA) pathway have altered expression in …
BACKGROUND: The aim of this study was to quantify blood vessel density (BVD) and immunoreactive vascular endothelial growth factor (VEGF) levels in endometrial biopsies taken from women suffering breakthrough bleeding (BTB) under different …
This review summarises recent research into the mechanisms and regulation of endometrial angiogenesis. Understanding of when and by what mechanisms angiogenesis occurs during the menstrual cycle is limited, as is knowledge of how it is regu…
Endometriosis is a complex disease which affects up to 10% of women in their reproductive years. Common symptoms include severe dysmenorrhea and pelvic pain. The disease is associated with subfertility and some malignancies. Genetic and env…
The aim of this study was to develop a mouse model to investigate the effects of long-term progestin-only exposure on endometrial vascular structure. Normal cycling mice received Silastic implants containing either medroxyprogesterone aceta…
Angiogenesis is defined as the formation of new blood vessels from the existing vasculature. Angiogenesis occurs regularly in the endometrium throughout the reproductive life of females as part of the rapid growth and regression of this tis…
The chapters in this section describe endometrial vascular structure and function, with particular emphasis on normal physiologic events such as growth, implantation, and menstruation, as well as pathologic situations such as endometriosis,…
It has been shown that the endometrium of women using progestin-only contraceptives has increased vascular fragility, although the structural basis for this weakness is unknown, as is its role in breakthrough bleeding (BTB). Perivascular ce…
Endometrial spiral arterioles are believed to play a major role in controlling menstruation. These arterioles coil and grow through the secretory stages of the cycle, unlike the 'straight' endometrial arterioles that remain uncoiled. We pos…
Excessive endometrial angiogenesis is proposed as an important mechanism in the pathogenesis of endometriosis. Evidence is reviewed for the hypothesis that the endometrium of women with endometriosis has an increased capacity to proliferate…
