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.

Association between baseline LH/FSH and live-birth rate after fresh-embryo transfer in polycystic ovary syndrome women

Scientific Reports, 2021
This study aimed to retrospectively analyse the effect of the baseline luteinising hormone/follicle-stimulating hormone ratio (bLH/FSH) on the live-birth rate per fresh-embryo transfer cycle (LBR/ET) in infertile women with polycystic ovary syndrome ...

Fresh versus frozen embryo transfers in assisted reproduction

Cochrane Database of Systematic Reviews, 2021
In vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) treatments conventionally consist of a fresh embryo transfer, possibly followed by one or more cryopreserved embryo transfers in subsequent cycles. An alternative option is to freeze all suitable embryos and transfer cryopreserved embryos in subsequent cycles only, which is known ...

Pro: Fresh versus frozen embryo transfer. Is frozen embryo transfer the future?

Human Reproduction, 2022
Abstract Embryo cryopreservation has been an integral part of ART for close to 40 years and vitrification has boosted overall ART efficacy and safety. Recently, there has been a vivid scientific discussion on whether elective cryopreservation of all embryos (freeze-all) should be pursued for most patients, with a fresh embryo transfer ...
