Single embryo transfer is an option in frozen embryo transfer [PDF]

Human Reproduction, 2005
A good strategy to decrease multiple pregnancy rate in assisted reproduction technology (ART) is the use of single embryo transfer (SET).This retrospective study analysed 1647 frozen embryo transfers carried out during 1998-2003 in Helsinki University Central Hospital; of these, 872 were double embryo transfers (DETs) and 775 SETs.

Oral dydrogesterone in frozen-thawed embryo transfer cycles [PDF]

Revista da Associação Médica Brasileira, 2022
The aim of this study was to compare the use of micronized vaginal progesterone and oral dydrogesterone in the endometrial preparation for frozen-thawed embryo transfer.This was a randomized, controlled, open, two-armed clinical trial, with women undergoing frozen-thawed embryo transfer along with hormone replacement therapy for endometrial preparation,

Effect of autologous platelet-rich plasma treatment on patients with thin endometrium

Revista Cubana de Medicina Militar, 2022
Introduction: The success of frozen embryo transfer cycles depends on a delicate interaction between embryo quality and endometrium. Low pregnancy rates are associated with a thin endometrium. Objective: To evaluate the effect of autologous platelet-rich

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.

Live birth after fresh embryo transfer vs elective embryo cryopreservation/frozen embryo transfer in women with polycystic ovary syndrome undergoing IVF (FreFro-PCOS): study protocol for a multicenter, prospective, randomized controlled clinical trial [PDF]

, 2014
BACKGROUND: Polycystic ovary syndrome (PCOS) patients are at increased risk of pregnancy complications, which may impair pregnancy outcome. Transfer of fresh embryos after superovulation may lead to abnormal implantation and placentation and further ...

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 ...

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]

, 2020
In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.
