background:   objective: to evaluate the effect of unilateral tubal blockage diagnosed by hsg on cumulative pregnancy rate (cpr) of the stimulated iui cycles.   materials and methods: a cross-sectional analysis was performed between october 2006 and october 2009 in an academic reproductive endocrinology and infertility center. two groups of patients undergoing stimulated iui cycles were compare...

OBJECTIVE The luteal phase after ovarian hyperstimulation for in vitro fertilization (IVF) is insufficient. Therefore, luteal phase supplementation is routinely applied in IVF. It may be postulated that premature luteolysis after ovarian hyperstimulation is due to supraphysiological steroid levels in the early luteal phase. In the present study, high doses of steroids are administered after the...

In the controlled ovarian hyperstimulation (COH) cycle of the in vitro fertilizationembryo transfer (IVF-ET) therapy, the clinicians observe the patients’ responses to gonadotropin dosages through closely monitoring their physiological states, to balance the trade-off between pregnancy rate and ovarian hyperstimulation syndrome (OHSS) risk. In this paper, we model the clinical practice in the C...

BACKGROUND AND OBJECTIVE To determine the prevalence of markers of inherited thrombophilia in patients with severe form of ovarian hyperstimulation syndrome (OHSS) DESIGN AND METHODS: Blood samples were analysed for markers of thrombophilia (mutation of factor V - Leiden, mutation of methylentetrahydrofolat reductase (MTHFR) C677T and mutation of prothrombin G20210A). The study group consisted ...

HMG-hCG therapy was performed on 109 patients who had previously received various forms of treatment but had failed to ovulate or become pregnant. From among the 109 patients, 80 (73.4%) succeeded in ovulation and 37 (33.9%) became pregnant. Ten patients with high FSH and low estrogen levels before the therapy failed to ovulate and were believed to have amenorrhea of ovarian origin. This indica...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is a recognized complication of ovulation induction, occurring in 1-10% of IVF and embryo transfer cycles. While mild OHSS is of no clinical relevance, severe OHSS is a life threatening complication. However, the efficacy of prevalent treatments appeared to be limited. We developed a continuous autotransfusion system with an ultrafiltration in...

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...

thromboembolic phenomena are the serious consequences of assisted reproductive technology. we present a case of cerebral sinus vein thrombosis (cvst) following ovarian hyper stimulation syndrome (ohss). ten days after recovering from ohss, the patient presented in the emergency department with thunderclap headache. her magnetic resonance venography (mrv) showed occluded left transverse sinus an...

BACKGROUND In human assisted reproduction, the ovarian response to exogenous recombinant Follicle-stimulating Hormone (FSH) therapy is variable and difficult to predict. The standard protocol of ovarian hyperstimulation can result in satisfactory response; however, an unsatisfactory response necessitates FSH dose adjustment or results in ovarian hyperstimulation syndrome (OHSS). Polymorphisms i...
