PURPOSE: This article presents a novel concept of the evolution and, thus, the pathogenesis of uterine adenomyosis as well as peritoneal and peripheral endometriosis. Presently, no unifying denomination of this nosological entity exists. M…

PURPOSE: In a series of publications, we had developed the concept that uterine adenomyosis and pelvic endometriosis as well as endometriotic lesions at distant sites of the body share a common pathophysiology with endometriosis constitutin…

Pelvic endometriosis, deeply infiltrating endometriosis and uterine adenomyosis share a common pathophysiology and may be integrated into the physiological mechanism and new nosological concept of 'tissue injury and repair' (TIAR) and may, …

INTRODUCTION: This study presents a unifying concept of the pathophysiology of endometriosis and adenomyosis. In particular, a physiological model is proposed that provides a comprehensive explanation of the local production of estrogen at …

Magnetic resonance imaging (MRI) allows the diagnosis of adenomyosis in vivo with a high sensitivity and specificity. Usually the diagnosis of adenomyosis is obtained from women in their fourth to fifth decade of life. However, recent data …

ObjectiveEnlargement of the junctional zone (JZ) on T2-weighted resonance imaging of the uterus has recently been established as the major criterion for adenomyosis in patients with endometriosis. This study was conducted to analyse the ext…

The uterus is composed of different smooth muscle layers that serve various functions. First, menstrual debris is expulsed at the time of the menses. Second, sperm is transported in the preovulatory phase to maximize fertility, and third, t…

Evidence has been provided that pelvic endometriosis is significantly associated with uterine adenomyosis and that the latter constitutes the major factor of infertility in such conditions. Furthermore, it has become evident that both adeno…

OBJECTIVE: Uterine hyperperistalsis and dysperistalsis are common phenomena in endometriosis and may be responsible for reduced fertility in cases of minimal or mild extent of disease. Since a high prevalence of adenomyosis uteri has been w…

BACKGROUND: The hypothesis is tested that there is a strong association between endometriosis and adenomyosis and that adenomyosis plays a role in causing infertility in women with endometriosis. METHODS. Magnetic resonance imaging of the u…

Peristaltic activity of the non-pregnant uterus serves fundamental functions in the early process of reproduction. Hyperperistalsis of the uterus is significantly associated with the development of endometriosis and adenomyosis. In women wi…

Peristaltic activity of the nonpregnant uterus serves fundamental functions in the early process of reproduction, such as directed transport of spermatozoa into the tube ipsilateral to the dominant follicle, high fundal implantation of the …

BACKGROUND: The hypothesis is tested that both adenomyotic and endometriotic lesions are derived from basal endometrium. METHODS: Normal uteri and uteri with adenomyosis obtained by hysterectomy, excised endometriotic lesions and menstrual…

Unlike other smooth muscle organs, the uterine muscle was regarded to be normally functional for only a brief period, following a lengthy gestation. However, recently it has been shown that uterine peristalsis constitutes one of the fundame…

In women with endometriosis, the peristaltic activity of the uterus is significantly enhanced and may even become dysperistaltic at midcycle. Since uterine peristalsis is confined to the endometrium and the subendometrial myometrium with it…

Endometriosis is considered primarily a disease of the endometrial-subendometrial unit or archimetra. The clinical picture of endometriosis characterises this disease as a hyperactivation of genuine archimetrial functions such as proliferat…

Rapid as well as sustained sperm transport from the cervical canal to the isthmical part of the fallopian tube is provided by cervico-fundal uterine peristaltic contractions that can be visualized by vaginal sonography. The peristaltic cont…

Women suffering from infertility in association with mostly mild endometriosis were subjected to vaginal sonography of uterine peristalsis during the menstrual period, the early, mid- and late follicular phases, and the mid-luteal phase of …

Estrogen deficiency results in bone mass reduction of largely varying extent in postmenopausal females, indicating that additional mechanisms influence the response of bone. They are by no ways identified in either the animal experiment or …

Oestrogen deficiency at the menopause is associated with changes in calcium and bone metabolism. Hypo-oestrogenism induced by the use of GnRH-agonists is clinically useful in the treatment of oestrogen-dependent diseases. This study was don…
