Can we improve implantation by cancellation of fresh embryo transfer?

Middle East Fertility Society Journal, 2013
Single embryo transfer is becoming increasingly popular in IVF/ICSI. More IVF/ICSI cycles therefore include freezing of high quality embryos, and the cumulative effect of such cycles becomes more important.

Thawed Day 3 Embryos Cultured to Blastocysts versus Thawed Blastocysts Transfer [PDF]

Zagazig University Medical Journal
Background: The optimal stage for embryo vitrification remains controversial. Whether thawed Day 3 cleavage embryos cultured to blastocyst stage yield better outcomes than directly thawed blastocysts in frozen Intracytoplasmic sperm injection (ICSI ...

Study protocol: E-freeze - freezing of embryos in assisted conception: a randomised controlled trial evaluating the clinical and cost effectiveness of a policy of freezing embryos followed by thawed frozen embryo transfer compared with a policy of fresh embryo transfer, in women undergoing in vitro fertilisation

Reproductive Health, 2019
Background Infertility affects one in seven couples; many of these need in vitro fertilisation (IVF). IVF involves external hormones to stimulate a woman’s ovaries to produce eggs which are harvested surgically.

Frozen-thawed transfer cycles: are they comparable with fresh?

, 2008
Cryopreservation of zygotes and subsequent thaw and transfer is an established ART treatment. We assessed if success rates frozen-thawed (day 2) zygotes are comparable with the outcome in fresh cycles of treatment.
