In-vitro fertilization (IVF) and ovarian stimulation are frequently performed in patients with endometriosis. Although endometriosis is a hormone-dependent disease, the rate of IVF complications related to endometriosis is low. We report fo…

Deep infiltrating endometriosis (deeper than 5 mm under the peritoneum) often takes the form of a nodular lesion (or 'adenomyotic nodule') consisting of smooth muscles and fibrosis with active glands and scanty stroma. Thus, among endometri…

Abnormal endometrial bleeding continues to be a significant problem for women using long-acting gestagens and not only reduces the use of these agents, thus restricting the options available to women, but also reduces the quality of their l…

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…

The aim of this study was to develop an objective test for superficial endometrial vascular fragility at hysteroscopy, and to apply this test to women using Norplant((R)) for contraception and to women with ovulatory dysfunctional uterine b…

We determined the expression of oestrogen receptor (ER), progesterone receptor (PR), heat shock protein 27 (HSP27) and human beta-lactoglobulin in the endometrium under hormone replacement therapy (HRT). The immunohistochemical expression d…

One common side-effect of contraceptive use is that it often leads to disrupted endometrial bleeding patterns. This may be due to changes in endothelial density and vessel integrity. To investigate whether the level of endometrial immunorea…

The use of progestogens without oestrogen is commonly associated with irregular menstrual bleeding. Oestrogens and progestogens are both thought to influence endometrial perfusion; changes in endometrial perfusion may contribute to vascular…

This paper explores the concept that endometrial breakthrough bleeding results from the stimulatory effects of oestrogen in the endometrium. Though 'progestin-only' contraceptive regimens have long been associated with user dissatisfaction …

Recent studies have provided substantial evidence to highlight abnormalities in the structure of endometrial microvessels in users of progestogen-only contraception. Structural changes alone are unlikely to lead to breakthrough bleeding, bu…

The objective of this study was to analyse the histological and immunohistochemical characteristics of cultured explants of human endometrium transplanted into nude mice. Biopsies of eutopic endometrium were taken from six patients during l…

Standard diagnostic laparoscopy is considered the gold standard to investigate tubo-peritoneal infertility. It requires general anaesthesia and full operative facilities. Due to the risk of complications, laparoscopy is frequently postponed…

Tumour necrosis factor alpha (TNFalpha) of peritoneal fluid is believed to have important pro-inflammatory and angiogenic activities in the complex mechanisms of development of peritoneal endometriotic lesions. We have evaluated the concent…

The non-pregnant uterus shows different patterns of contractility during the menstrual cycle. A renewed interest in uterine contractility has resulted from reports of non-invasive ultrasound (US) based studies. To clarify the changes in ute…

Endometrial growth is thought to depend on uterine artery blood flow and the importance of endometrial development on in-vitro fertilization (IVF) outcome has been previously reported. Nitric oxide (NO) relaxes vascular smooth muscle throug…

In order to analyse the efficacy of resection/ablation of minimal/mild endometriotic lesions for improving fertility, we conducted a randomized clinical trial. Eligible patients were women aged </=36 years who were trying to conceive and ha…

We have investigated the adhesion of endometrial tissue isolated from antegradely shed menstrual effluent to amnion and peritoneum. This endometrial tissue was cultured overnight on either side of intact and stripped amnion and on the mesot…

Recurrent miscarriage is a difficult clinical problem occurring in approximately 1-2% of fertile women. Following investigation, most cases fail to reveal an identifiable cause and are therefore classified as idiopathic. The aim of this stu…

The purpose of this study was to determine the association of antibodies to thyroglobulin and thyroid peroxidase and pregnancy outcome in women undergoing assisted reproductive techniques. The study included three centres and retrospectivel…

We report the first case of an ectopic twin pregnancy in the broad ligament following in-vitro fertilization and embryo transfer in a patient with a previous ipsilateral (left) salpingo-oophorectomy. The previous surgery was for endometrios…

Progestogen-only contraception is almost invariably associated with changes in menstrual bleeding patterns. Changes in the endometrial vasculature, and in particular an increase in vascular fragility, may contribute to this bleeding. In thi…

In this study, we compare the prognostic significance of hysterosalpingography (HSG) and laparoscopy for fertility outcome. In a prospective cohort study in 11 clinics participating in the Canadian Infertility Treatment Evaluation Study (CI…

Genital tract abnormalities and adverse pregnancy outcome are well known in women exposed in utero to diethylstilboestrol (DES). Data about adverse reproductive performance in women exposed to DES have been published, including controversia…

The effect of treatment with danazol was evaluated with respect to expectant management after laparoscopic conservative surgery. All patients conservatively operated at laparoscopy for stage III-IV endometriosis from July 1994 to October 19…
