Risk-adapted management for vasa praevia: a retrospective study about individualized timing of caesarean section

PurposeVasa praevia is a rare condition with high foetal mortality if not detected prenatally. There is limited evidence available to determine the ideal timing of delivery and management recommendations. The aim of this study was to critically review our experience with vasa praevia, with a focus on diagnosis and management.MethodsIn a retrospective analysis, all cases of vasa...

The effect of slow release insemination on pregnancy rates: report of two randomized controlled pilot studies and meta-analysis

Purpose A modified application technique of intrauterine insemination (IUI) is slow release insemination (SRI), first described by Muharib et al. (Hum Reprod 7(2):227–229, 1992), who postulated higher pregnancy rates with a slow release of spermatozoa for 3 h. Methods To investigate this approach, two randomized controlled, cross-over pilot studies were performed from 2004 to...

The predictive value of sequential cervical length screening in singleton pregnancies after cerclage: a retrospective cohort study

Background There are few valid predictors for preterm delivery after cerclage. Experience with a screening program that included four sequential cervical length measurements in singleton pregnancies after cerclage is reviewed. Methods In this retrospective cohort study, 88 singleton pregnancies after cerclage were included. Cervical length (CL) measurements were performed...

Predictive value of the time interval between embryo loading and transfer for IVF/ICSI success: a prospective cohort study

Background The influence of embryo loading time (ELT) and the time interval between embryo loading and embryo transfer (TIEL-ET) on the success of IVF/ICSI is unknown. Methods In a prospective cohort study, we aimed to ascertain the influence of ELT and TIEL-ET on ongoing pregnancy rate (OPR) and life birth rate (LBR). Data from 603 consecutive embryo transfers between January...

Obstetric and perinatal outcomes in IVF versus ICSI-conceived pregnancies at a tertiary care center - a pilot study

Background Although most pregnancies after IVF result in normal healthy outcomes, an increased risk for a number of obstetric and neonatal complications, compared to naturally conceived pregnancies, has been reported.
