embryo transfer in all situations if a top - quality blastocyst is available.
Embryo donation does, however, share some similarities because it involves non-genetic parenting, and for that reason is sometimes called «
Embryo Adoption» by adoption agencies that
use the adoption model to facilitate
transfer from the parents who created the
embryos to the intended parents.
Depending on the kind of
embryo used — fresh or frozen — the timing of the
transfer will differ.
Embryos created through somatic cell nuclear
transfer, which
uses skin cells taken from the sick child, could also be
used to test therapies.
Freezing and subsequent
transfer of
embryos gives infertile couples just as much of a chance of having a child as
using fresh
embryos for in vitro fertilization (IVF), research from Ho Chi Minh City, Vietnam, and Adelaide, Australia has found.
Women were given one cycle of IVF, where either a
transfer of fresh
embryos occurred, or all
embryos were frozen and one cycle of thawed
embryos occurred subsequently without the
use of IVF drugs.
To solve this, West proposed «therapeutic cloning» — taking the nucleus out of a patient's cell,
transferring it into an egg cell to create a cloned
embryo, then
using that
embryo to derive patient - matched stem - cell lines.
This technique is already

The timing of pronuclei
transfer (better early after fertilization, about 8 hours after insemination, referred to as «ePNT»), changes to the manipulation medium (removing calcium and magnesium, and reducing the amount of the protein that mediates the fusion event), and the
