Outcomes of singleton births after blastocyst versus nonblastocyst transfer in assisted reproductive technology.

Objective: To compare obstetric and perinatal outcomes of singleton births after assisted reproductive technology (ART) with blastocyst transfer (days 5 to 6) versus nonblastocyst transfer (days 2 to 4).

Design: Retrospective cohort study.

Setting: Monash IVF.

Cerebral palsy and assisted reproductive technologies: a case-control study.

Aim: To determine whether assisted reproductive technologies (ART) were more likely to be the method of conception in singletons with cerebral palsy (CP) than in those without CP.

Method: Singletons with CP born between 1991 and 2004 were selected from the Victorian Cerebral Palsy Register and matched for birth year to two singletons randomly selected from the Victorian Perinatal Data Collection Unit. Data from both sources were linked to records from three ART centres.
