OBJECTIVE To critically evaluate the P to oocyte (O) ratio (P/O) in the prediction of live birth in assisted reproductive technology (ART) cycles. DESIGN Retrospective cohort study. SETTING Not applicable. PATIENT(S) A total of 7,608 fresh autologous ART ET cycles. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Live birth. RESULT(S) Generalized estimating equation (GEE) models and re...

OBJECTIVE To determine whether in vitro fertilization with preimplantation genetic screening (IVF/PGS) is cost effective compared with expectant management in achieving live birth for patients with unexplained recurrent pregnancy loss (RPL). DESIGN Decision analytic model comparing costs and clinical outcomes. SETTING Academic recurrent pregnancy loss programs. PATIENT(S) Women with unexp...

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 This study was done to test the hypothesis that intrauterine insemination (IUI) using a soft-tip catheter results in a higher live birth rate than IUI using a hard-tip catheter. METHODS Five hundred and forty patients were randomized into those inseminated with a soft-tip catheter (group 1, n = 267) and those inseminated with a hard-tip catheter (group 2, n = 269). Four patients we...

Background: In vitro fertilization (IVF) has become increasingly common, today representing about 3% of all live births in some countries. Most patients have to undergo more than one treatment in order to achieve a live birth. Thus cumulative live birth rates are highly interesting to the patients. The most important health problem in IVF is the high rate of multiple births, leading to increase...

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...
