INTRODUCTION Sperm chromatin integrity assessment has been suggested as a fertility predictor. The aim of this study was to examine the relationship between the results of sperm chromatin structure assay (SCSA) and the outcome of IVF, ICSI and intrauterine insemination (IUI). METHODS A total of 306 consecutive couples undergoing assisted reproduction were included. IUI was performed in 131, I...

BACKGROUND An increased risk of major congenital abnormalities after IVF and ICSI has been described, but underlying mechanisms are unclear. This study evaluates the effects of ovarian hyperstimulation, the in vitro procedure and time to pregnancy (TTP) - as proxy for the severity of subfertility - on the prevalence of dysmorphic features. DESIGN/METHODS Participants were singletons born foll...

BACKGROUND A good response rate has been considered as a proof of a study's quality. Decreasing participation and its potential impact on the internal validity of the study are of growing interest. Our objective was to assess factors associated with contact and response to a postal survey in a epidemiological study of the long-term outcome of IVF couples. METHODS The DAIFI study is a retrospe...

A retrospective analysis of clinical and laboratory data was made of all in-vitro fertilization (IVF) patients with tubal pathology who had their first ever embryo transfer cycle between January 1st, 1992 and September 1st, 1996. The aim of the study was to determine the effect of the presence of a hydrosalpinx, whether or not visible by ultrasound, on pregnancy, multiple pregnancy and implanta...

We aimed to prospectively investigate the paternal antigen-induced cytokine secretion by peripheral blood mononuclear cells (PBMCs) in response to hormone treatment in women undergoing in vitro fertilisation (IVF) and to examine the predictive value of the cytokine secretion profile in the outcome of IVF treatment, in a pilot study. Twenty-five women were included and IVF treatment was successf...

BACKGROUND While live birth is the principal clinical outcome following in vitro fertilization (IVF) treatment, the number of eggs retrieved following ovarian stimulation is often used as a surrogate outcome in clinical practice and research. The aim of this study was to explore the association between egg number and live birth following IVF treatment and identify the number of eggs that would ...
