The difference in early trimester fetal growth between singletons after frozen embryo transfer and fresh embryo transferAJOG Global Reports at a Glance

AJOG Global Reports
BACKGROUND: Frozen embryo transfer resulted in a higher birthweight and an increased risk of macrosomia than fresh embryo transfer. However, the mechanism was still unclear.

Fresh versus frozen embryo transfers for assisted reproduction [PDF]

Cochrane Database of Systematic Reviews, 2014
In general, in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) implies a single fresh and one or more frozen-thawed embryo transfers. Alternatively, the 'freeze-all' strategy implies transfer of frozen-thawed embryos only, with no fresh embryo transfers.
