uterine and arcuate arteries blood flow for predicting of ongoing pregnancy in in vitro fertilization
background: in this study, we aimed to investigate the ability of transvaginal doppler ultrasonography in predicting in vitro fertilization (ivf) outcome in women undergoing this procedure. materials and methods: in this prospective observational study, 65 infertile women underwent ivf procedure in isfahan, during 2013-2014, were studied. the pulsatility index (pi), resistive index (ri) and pea...
متن کاملPrognostic models for the probability of achieving an ongoing pregnancy after in-vitro fertilization and the importance of testing their predictive value.
The aim of this study was to create reliable models to predict the probability of achieving an ongoing pregnancy during in-vitro fertilization (IVF) treatment: model A, at the start of the first treatment, model B at the time of embryo transfer, and model C, during the second treatment at the end of the first IVF treatment. Prognostic models were created using data from the University Hospital ...

متن کاملHeterotopic pregnancy after in vitro fertilization and embryo transfer.
We have presented a second case of heterotopic pregnancy after IVF-ET. The most likely cause is direct extrusion of embryos through the tubal ostia by the hydrostatic pressure associated with ET. The diagnosis of ectopic pregnancy must be suspected clinically and not ruled out on the sonographic demonstration of an intrauterine pregnancy. Early diagnosis is essential for the prevention of signi...
