Background Idiopathic ventricular fibrillation (IVF) is a rare cause of sudden cardiac arrest. IVF is currently defined as a resuscitated cardiac arrest victim, preferably with documentation of ventricular fibrillation (VF), in whom known cardiac, respiratory, metabolic, and toxicological causes have been excluded through clinical evaluation. In other words, IVF is diagnosed after exclusion of ...

BACKGROUND This research describes current clinical and demographic features sampled from reproductive endocrinology programs currently offering in vitro fertilization (IVF) in the Middle East. METHODS Clinic leadership provided data via questionnaire on patient demographics, demand for IVF services, annual cycle volume, indications for IVF, number of embryos transferred, twinning frequency, ...

BALB/c mice are widely used in genetic, tumour and immunological studies. However, the mice demonstrate a lower reproduction rate, low fertility and small litters, because of their highly genetic homozygoisty. Based on in vitro fertilization (IVF), a routine technique for biomedical studies, it is worth to evaluate the effects to BALB/c mice on IVF efficiency. In order to test the genetic facto...

The number of children born since the origin of Assisted Reproductive Technologies (ART) exceeds 5 million. The majority seem healthy, but a higher frequency of defects has been reported among ART-conceived infants, suggesting an epigenetic cost. We report the first whole-genome DNA methylation datasets from single pig blastocysts showing differences between in vivo and in vitro produced embryo...

BACKGROUND To gain more insight in whether failure of intrauterine insemination (IUI) treatment in patients with idiopathic subfertility could be related to diminished fertilization, the aim of this study is to compare the fertilization of an initial IVF procedure after six cycles of IUI and the fertilization of an initial IVF procedure without preceding IUI cycles in couples with idiopathic su...

BACKGROUND We will assess to what extent in vitro fertilization (IVF) is effective in increasing the number of births overall and whether earlier application of IVF will increase this number. METHODS We simulate 100 000 women trying for their first and second child. Natural and IVF pregnancy rates and infertility rates are age-dependent and based on published data. The age at which women star...

In Vitro Fertilization Genetic Algorithm (IVF/GA) is a recently created algorithm that combine the concepts of Genetic Algorithm and In Vitro Fertilization. The IVF/GA has the aim to improve the performance of Genetic Algorithm with the addition of IVF-Inspired mechanisms that better exploit the information of individuals. The Multimensional Knapsack Problem (MKP) is a complex combinatorial pro...

In vitro fertilization (IVF) with reception of oocytes from partners (ROPA) allows lesbian mothers to share biological motherhood. The gestational mother receives an egg from her partner who becomes the genetic mother. This article examines the ethics of IVF with ROPA with a focus on the welfare of the woman and the resulting child, on whether ROPA qualifies as a "legitimate" medical therapy th...

BACKGROUND Women conceiving following in vitro fertilization (IVF) likely have a variety of risk factors that predispose them to gastroesophageal reflux disease (GERD) in the future. OBJECTIVE We aimed to investigate whether pregnancy through IVF may predispose to subsequent GERD compared with pregnancies without IVF. We also evaluate whether twin IVF pregnancies lead to additional risk for h...
