Clinical studies have suggested that hormone replacement therapy (HRT) may reduce the risk of coronary heart disease in postmenopausal women. Although progestins are commonly added to HRT preparations for uteroprotection, the perceived beneficial cardiovascular effects of HRT are thought to be mediated predominantly by the estrogen component. Platelets play(More)
BACKGROUND Local biosynthesis of estrogens is thought to be important for the maintenance and growth of endometriotic implants. In addition to the formation of estrogen via the aromatase pathway, steroid sulphatase (STS), which is responsible for the hydrolysis of estrogen sulphates, may be an important source of estrogens in endometriosis.

Progesterone is central to many reproductive processes and is critical in regulating the menstrual cycle and maintaining pregnancy. We discuss here similarities in the molecular mechanisms that regulate the process of decidualisation in endometrial stromal cells and uterine quiescence in myometrial smooth muscle cells. We discuss recent evidence that the(More)
Endometriosis is a common and debilitating condition of women in their reproductive age that is associated with pain and infertility. Current medical treatments are only partially effective and associated with wide-ranging side effects. New understanding of local estrogen production by endometriotic tissue and the availability of powerful suppressing drugs(More)
OBJECTIVE To assess the feasibility of CO2-laser-endoscopic surgical treatment for large and/or ruptured ectopic pregnancies, and to compare the results with those of microsurgical salpingotomy. DESIGN A retrospective review of all women treated for an ectopic pregnancy during a 6-year period, 1984-1989. During 1988 and 1989 treatment was randomized by(More)
When trying to conceive 1% of couples have recurrent miscarriages, defined as three or more consecutive pregnancy losses. This is not accounted for by the known incidence of chromosomal aneuploidy in miscarriage, and it has been suggested that there is an immunological aetiology. The endometrial mucosa is populated by a variety of immune cells which in(More)
