BACKGROUND The objective of this study was to identify baseline predictors of live birth in anovulatory patients undergoing ovulation induction, and based on these predictors, develop nomograms for estimation of the probability of live birth in a single cycle. METHODS Univariate and multivariate logistic regression were used for retrospective analysis of clinical, sonographic and endocrinolog...
STUDY QUESTION Can the pronuclei (PN) morphology and the time of PN breakdown (PNB) predict the potential of embryos to result in live birth? SUMMARY ANSWER In comparison to embryos resulting in no live birth, PNB occurred significantly later in embryos resulting in live birth and never earlier than 20 h 45 min. None of the tested scoring systems were shown to predict the live birth outcome i...
BACKGROUND Variation in birth registration criteria may compromise international comparisons of fetal and infant mortality. We examined the effect of birth registration practices on fetal and infant mortality rates to determine whether observed differences in perinatal and infant mortality rates were artifacts of birth registration or reflected true differences in health status. METHODS A ret...
OBJECTIVES Newborn screening for cystic fibrosis (CF) facilitates early diagnosis and genetic counselling for parents of affected infants. Many parents elect to use prenatal testing for subsequent pregnancies, and this may affect the prevalence of CF. The aim of this study was to assess the evidence for changes in the live-birth prevalence of CF since the introduction of newborn screening for C...
Few reports provide pregnancy or birth rates for large groups of infertile couples having a comprehensive range of treatments. This model utilizes published evidence about diagnosis, treatment, the duration of treatment and the proportion of couples receiving treatment. Assisted reproduction technology treatment (ART) utilization was set arbitrarily at three levels: 3, 10 or 50% of the couples ...
Background: The aim of this retrospective study is to investigate the cumulative live birth rate (CLBR) following one or more completed in vitro fertilization (IVF) cycles (up to 6 cycles) stratified by maternal age and type of infertility. Materials and Methods: In this retrospective study, five hundred forty-seven women who received 736 fresh ovarian stimulation/embryo transfer cycles between...
