OBJECTIVE To determine to what extent institutions carrying out in vitro fertilisation can reasonably be ranked according to their live birth rates. DESIGN Retrospective analysis of prospectively collected data on live birth rate after in vitro fertilisation. SETTING 52 clinics in the United Kingdom carrying out in vitro fertilisation over the period April 1994 to March 1995. MAIN OUTCOME...
INTRODUCTION This study is part of a longitudinal cohort undertaken in both women and men to describe live birth outcome after undergoing assisted reproductive technology (ART) treatment in a clinical setting. Another objective was to follow women and men living with children from other alternatives after ART, such as adoption. MATERIAL AND METHODS A total of 439 (80.5%) women and 423 (77.6%)...
background: singleton pregnancy with a live birth beyond 37 weeks of gestation is the ultimate goal of any assisted reproductive technology. however, singletons conceived after art are found to have a poor perinatal outcome in comparison to naturally conceived singletons. it was hypothesized that the outcome of singleton conceived after transfer of two or more embryos may be dependent on the sh...
OBJECTIVE The aim of this study was to evaluate pregnancy outcomes and the live birth rate at 1-year age increments in women aged ≥40 years undergoing fresh non-donor in vitro fertilization (IVF) and embryo transfer (ET), and to identify predictors of success in these patients. METHODS This retrospective study was performed among women ≥40 years of age between 2004 and 2011. Of the 2,362 cycl...
Background Polycystic ovary syndrome (PCOS) is a common and complex condition affecting up to 18% of reproductive-aged women with reproductive, metabolic and psychological dysfunction. We performed an overview and appraisal of methodological quality of systematic reviews assessing medical and surgical treatments for reproductive outcomes in women with PCOS. Methods This was an overview of syste...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
BACKGROUND The average age of women bearing their first child has increased strongly. This is an important reproductive health problem as fertility declines with increasing female age. Unfortunately, IVF using fresh oocytes cannot compensate for this age-related fertility decline. Oocyte freezing could be a solution. METHODS We used the Markov model to estimate the cost-effectiveness of three...
