BACKGROUND The three approaches to hysterectomy for benign disease are abdominal hysterectomy (AH), vaginal hysterectomy (VH), and laparoscopic hysterectomy (LH). Laparoscopic hysterectomy has three further subdivisions depending on the part of the procedure performed laparoscopically. OBJECTIVES To assess the most beneficial and least harmful surgical(More)
OBJECTIVE To assess the value of antimullerian hormone (AMH) as a test to predict poor ovarian response and pregnancy occurrence after IVF and to compare it with the performance of the antral follicle count (AFC). DESIGN A systematic review of existing literature and a meta-analysis were carried out. After a comprehensive search, studies were included if(More)
The age-related decline of the success in IVF is largely attributable to a progressive decline of ovarian oocyte quality and quantity. Over the past two decades, a number of so-called ovarian reserve tests (ORTs) have been designed to determine oocyte reserve and quality and have been evaluated for their ability to predict the outcome of IVF in terms of(More)
CONTEXT The literature contains a large number of potential biases in the evaluation of diagnostic tests. Strict application of appropriate methodological criteria would invalidate the clinical application of most study results. OBJECTIVE To empirically determine the quantitative effect of study design shortcomings on estimates of diagnostic accuracy. (More)
OBJECTIVE To evaluate the effects of dietary and lifestyle interventions in pregnancy on maternal and fetal weight and to quantify the effects of these interventions on obstetric outcomes. DESIGN Systematic review and meta-analysis. DATA SOURCES Major databases from inception to January 2012 without language restrictions. STUDY SELECTION Randomised(More)
BACKGROUND The diagnosis of ectopic pregnancy can now often be made by non-invasive methods due to sensitive pregnancy tests (in urine and serum) and high resolution transvaginal sonography, which have been integrated in diagnostic algorithms. These algorithms, in combination with the increased awareness and knowledge of risk factors among both clinicians(More)
BACKGROUND Anti-Mullerian hormone (AMH) is a marker of ovarian reserve status and represents a good predictor of ovarian response to ovarian hyperstimulation. The aim of this study was to assess the accuracy of AMH and antral follicle count (AFC) as predictors of an excessive response in IVF/ICSI treatment. METHODS A systematic review and meta-analysis of(More)
BACKGROUND Mechanical methods were the first methods developed to ripen the cervix and induce labour. During recent decades they have been substituted by pharmacological methods. Potential advantages of mechanical methods, compared with pharmacological methods, may include simplicity of preservation, lower cost and reduction of the side effects. (More)
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 (CITES), consecutive couples who registered between 1 April 1984 and 31 March 1987 for the evaluation of subfertility and(More)
BACKGROUND Prediction models have been developed in reproductive medicine to help assess the chances of a treatment-(in)dependent pregnancy. Careful evaluation is needed before these models can be implemented in clinical practice. METHODS We systematically searched the literature for papers reporting prediction models in reproductive medicine for three(More)
