Coasting, embryo development and outcomes of blastocyst transfer: a case-control study.

This study compared the effect on blastocyst development and clinical outcome of coasting in women at increased risk of moderate-severe ovarian hyperstimulation syndrome (OHSS; n=389) with a control group matched for age and basal FSH that did not undergo coasting (n=386) in IVF/intracytoplasmic sperm injection (ICSI) cycles. The main outcome measures were rate of blastocyst development and live birth. More cycles progressed to the blastocyst stage in the coasted group (n=169) compared with the control group (n=83; 43.

Perinatal outcomes in oocyte donor pregnancies.

Objective: To assess the obstetric outcomes of pregnancy following intracytoplasmic sperm injection (ICSI) using donor oocytes.

Methods: Twenty-six deliveries from oocyte donor ICSI (d-ICSI) were compared to the next two consecutive deliveries from homologous ICSI (h-ICSI group) (n = 52) and with the two consecutive deliveries from women older than 40 years (Advanced Maternal Age: AMA) (n = 52). We evaluated the occurrence of gestational hypertension (GH), preeclampsia (PE), fetal growth restriction (IUGR), gestational diabetes mellitus (GDM), preterm premature rupture of membranes (pPROM), preterm birth, placental anomalies, mode of delivery, hemorrhage, gestational age at birth and birth weight.
