DESIGN Prospective cohort study. SETTING Twenty-five of 25 ART centers in Canada. PARTICIPANT(S) Couples undergoing ART treatment in Canada during 2005. INTERVENTION(S) ART treatments, including IVF, intracy...

BACKGROUND Many stillbirths show evidence of fetal growth restriction, and most occur at preterm gestational age. The objective of this study is to compare birth weights at preterm gestational ages between live births and stillbirths, and between those occurring before or during labour. METHODS Based on singleton births from the United States (U.S.) 2003-2005 (n=902,491) and Sweden 1992-2001 ...

OBJECTIVE To present a report on assisted reproductive technologies (ART) cycles performed in 2006 in Canada and show trends in outcomes over time. This is the sixth annual report from the Canadian ART Register (CARTR). DESIGN Prospective cohort study. SETTING Twenty-five of 25 ART centers in Canada. PATIENT(S) Couples undergoing ART treatment in Canada during 2006. INTERVENTION(S) ART ...

BACKGROUND Preimplantation genetic screening (PGS) has increasingly been used in the past decade. Here we present a systematic review and meta-analysis of RCTs on the effect of PGS on the probability of live birth after IVF. METHODS PubMed and trial registers were searched for RCTs on PGS. Trials were assessed following predetermined quality criteria. The primary outcome was live birth rate p...

OBJECTIVE To assess the relationship between the ethnicity of women and the clinical success of in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) treatment. DESIGN Observational cohort study. SETTING Nottingham University Research and Treatment Unit in Reproduction (NURTURE), UK. SAMPLE A total of 1517 women, of which 1291 were white Europeans and 226 belonged to an ...

OBJECTIVE We compared 12-month pregnancy and live birth rates in patients with polycystic ovarian disease undergoing 5-, 10-, and 15-point laparoscopic ovarian electrocauterization. METHODS This was a prospective, randomized study performed at the Dabirashrafi Fertility and Endoscopy Research Center, Tehran, Iran. The study included 187 patients with polycystic ovarian disease who were random...

Aim It was examined whether the single embryo transfer policy makes the treatment period longer for couples to achieve their first live birth by assisted reproductive technology. Methods This study retrospectively analyzed women who started assisted reproductive technology at younger than 40 years of age in the authors' organization. The treatment periods for couples to achieve the first live...

OBJECTIVE To establish a method of estimating the proportion of women with a subsequent live birth after a well-defined time period in an open cohort of women referred to a tertiary recurrent miscarriage clinic. METHODS We performed a descriptive cohort study with register-based follow-up at a tertiary center for investigation and treatment of recurrent miscarriage in Denmark. All women with ...

OBJECTIVE To evaluate, retrospectively, the roles of endogenous and exogenous luteinising hormone (LH) activity on live birth rate in ovulation induction cycles. METHODS Associations between LH activity at baseline, end of stimulation and live birth rate were analysed in relation to patient characteristics, baseline and end of stimulation variables in WHO group II anovulatory women (n = 155) ...

Background: To assess whether Bromocriptine Rebound Method (BRM), can improve pregnancy outcomes after intracytoplasmic sperm injection (ICSI) cycles. Materials and Methods: In this prospective study, we analyzed data from a total of 117 women who underwent ICSI cycles. Pregnancy outcomes and hormonal data were compared between long protocol and BRM groups. Ovulatory women with normal serum pro...
