Membrane proteins of the claudin superfamily are important components of cellular tight and adherens junctions. Although their exact function remains unclear, these proteins may play a role in tissue remodeling, a process which is associate…

BACKGROUND: The metalloproteinases (MMPs) are a family of proteolytic enzymes involved in tissue remodeling and cell migration. Endometrial tissue remodeling proceeds during the menstrual cycle and requires a temporary and spatially balance…

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…

During the use of long-cycle regimens of monophasic oral contraceptives, the total number of bleeding and cycle-dependent complaints is considerably lower than during conventional treatment with oral contraceptives. Despite an initially hig…

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…

OBJECTIVE: To investigate uterotubal transport by means of hysterosalpingoscintigraphy (HSSG) in women with and without endometriosis. DESIGN: A prospective observational study. SETTING: University Hospital, Department of Obstetrics and Gyn…

BACKGROUND: Uterine peristalsis sustains sperm transport and can be detected by hysterosalpingoscintigraphy (HSSG). This study is the first to be designed to investigate utero-tubal transport function by HSSG and uterine contractility by in…
