Recent evidence shows that through best standard operating procedures, chances of successful pregnancy and live birth delivery rates are less than 50%. Repeated Implantation Failure (RIF) following transfer of one or more numbers of cleavage or blastocyst stage embryos is the main cause of low pregnancy rate in IVF cycles; therefore, finding the causes and modifying treatment protocols to incre...
In women undergoing in vitro fertilization (IVF) who have an implantation failure (IF) after repeated embryo transfer, an association with the presence of acquired thrombophilia has been demonstrated, and a thromboprophylaxis seems to be efficacious in improving implantation rate. More recently a role inherited trombophilia has been recognised to have a role in recurrent otherwhise unexplained ...
BACKGROUND Infertility affects between 10 and 16% of couples worldwide. Twenty to 30% of cases of infertility are due to a male factor, 20-35% to a female factor, and 25-40% are due to both male and female factors. In ∼10-25% of cases, the precise underlying cause remains unclear. IVF or ICSI followed by embryo transfer can be very appropriate treatment options in cases of female tubal damage, ...
Endocrine disrupting chemicals (EDCs) are chemicals that have the capacity to interfere with normal endocrine systems. Two EDCs, bisphenol A (BPA) and triclosan (TCS), are mass-produced and widespread. They both have estrogenic properties and similar chemical structures and pharmacokinetic features and have been detected in human fluids and tissues. Clinical evidence has suggested a positive as...
BACKGROUND Our aim was to study ways to improve IVF success rates in women with suspected endometrial receptivity defects. METHODS We conducted a retrospective cohort study examining the effect of letrozole (aromatase inhibitor) on integrin expression as a marker of endometrial receptivity. We compared IVF outcomes in 97 infertile women who had undergone ανβ3 integrin assessment by immunohist...
Sudden cardiac death is a common outcome of several cardiac disorders such as acute myocardial ischemia, myocardial infarction, and heart failure. However, 5% to 15% of cardiac arrest victims fail to show evidence of structural abnormalities at autopsy.1–3 In 1997, a panel of experts defined sudden death in the absence of an identifiable cause as idiopathic ventricular fibrillation (IVF): “IVF ...

BACKGROUND Success rates of assisted reproductive techniques (ART) are approximately 30%, with the most important limiting factor being embryo implantation. Mechanical endometrial injury, also called 'scratching', has been proposed to positively affect the chance of implantation after embryo transfer, but the currently available evidence is not yet conclusive. The primary aim of this study is t...
BACKGROUND Dehydration from viral gastroenteritis is a significant pediatric health problem. Oral rehydration therapy (ORT) is recommended as first-line therapy for both mildly and moderately dehydrated children; however, three quarters of pediatric emergency medicine physicians who are very familiar with the American Academy of Pediatrics recommendations for ORT still use intravenous fluid the...
