The fetal endometrium becomes responsive to steroid hormones around the fourth month of pregnancy starting with an oestrogenic phase, which is followed late in pregnancy by a secretory phase. Based on post-mortem studies, the endometrium at…
In 1908, Cullen described the first cases of cystic adenomyosis in his textbook on adenomyomata. Although not very common, with the introduction of noninvasive imaging techniques such as magnetic resonance imaging (MRI) and 3-D transvaginal…
The pathogenesis of early-onset endometriosis has recently been revisited, sparked by the discovery of endometrial stem/progenitor cells and their possible role in endometriosis, and because maternal pregnancy hormone withdrawal following d…
INTRODUCTION: Several selective progesterone receptor modulators (SPRMs) show promise in several areas of medicine and this work has been summarized by us in 2008. AREAS COVERED: Since the publication of our reviews, several developments h…
A dispute has recently emerged whether early descriptions exist of the condition we name endometriosis. A first question is: 'Who identified endometriosis?' To respond, two non-complementary methods have been employed: searching for ancient…
PURPOSE OF REVIEW: We adopted a life-cycle approach to further our understanding of the natural history of the cystic forms of uterine adenomyosis first described by Cullen in 1908. SEARCH STRATEGY: Scopus and PubMed were searched for all …
There are now convincing data showing that cystectomy of the endometrioma is not only no cure of infertility, but may harm follicle reserve. The question arises why is cystectomy for an endometrioma, in contrast with other -benign cysts, a …
To improve the still fragmented understanding of endometriosis, a life cycle approach was adopted that revealed unexpected aspects of the natural history of the disease throughout a woman's life. Three age-related stages of endometriosis ar…
Endometriosis in the adolescent has, in recent years, been discovered to be a challenging problem in gynaecology. Although the pain may start at a young age, even before the onset of menstruation, the diagnosis by laparoscopy is almost alwa…
Adverse living and nutritional conditions in utero and in early infancy may influence the risk of diseases in adult life, because fetal growth seems determined by interactions between the environment and the fetal genome and these interacti…
We elaborate on a new theory to explain pelvic endometriosis, including endometriosis in premenarcheal girls, based on the finding that the neonatal endometrium can display secretory activity immediately after birth and, in some cases, chan…
Present management of the ovarian endometrioma focuses on the size of the cyst and dictates that surgery should not be performed unless this exceeds 3 cm, which neglects the complex pathology of this condition. Studies of ovaries with the e…
BACKGROUND Adenomyosis and endometriosis were initially described as 'adenomyoma'. When the retrograde menstruation theory became widely accepted to explain the pathogenesis of endometriosis, since it does not explain adenomyosis, the two c…
The incidence of endometriosis in the infertile female is estimated to be between 20 and 50 %. Although the causal relationship between endometriosis and infertility has not been proven, it is generally accepted that the disease impairs rep…
Endometriosis and adenomyosis are characterized by the presence of ectopic endometrium, but are also associated with functional and structural changes in the eutopic endometrium and inner myometrium. Alterations in the inner myometrium occu…
The transvaginal access for exploration of tubo-ovarian function in women with unexplained infertility has been revived since transvaginal hydrolaparoscopy (THL) was introduced in 1998. One prospective double-blind trial and several reviews…
Bleeding from endometriotic implants is now an established cause of acute hemoperitoneum in pregnancy. However, the adverse impact of pelvic endometriosis on uterine function before conception may also interfere with subsequent deep placent…
Eutopic and ectopic endometria of women with adenomyosis show a series of metabolic and molecular abnormalities that increase angiogenesis and proliferation, decrease apoptosis, allow local production of estrogens, create progesterone resis…
The eutopic endometrium in women suffering from endometriosis is different in many ways from that of healthy controls. Both proliferative and secretory eutopic endometria exhibit changes in endometriosis with heterogeneous responses. In add…
The diagnosis of adenomyosis using noninvasive techniques such as vaginal ultrasounds and magnetic resonance has clear clinical applications and has renewed the interest in the pathogenesis of uterine adenomyosis. However, the research rema…
The identification of endometriosis has been a subject of intense debate over the last decade. There is, however, no doubt that Thomas Cullen was the first to describe endometriosis and adenomyosis as one disease characterized by the presen…
Since the dissociation between adenomyoma and endometriosis in the 1920s and the laparoscopic progress in the diagnosis and surgery of endometriosis, the literature has been greatly focused on the disease endometriosis. The study of adenomy…
