Some clinic will not
transfer embryos created and frozen at another clinic, so travel may be required to the clinic where the embryos are frozen or created or stored.

created from sperm from the second partner.

creating and
transferring two
embryos, one from each partner.

transfer — or two -
embryo transfer — in which each
embryo is
created with the sperm of one partner.
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.
Embryos created through somatic cell nuclear
transfer, which uses skin cells taken from the sick child, could also be used to test therapies.
For reproductive cloning - which
creates animals with an identical genetic make - up to an already existing animal - the
embryo must then be
transferred to a host body, in which to grow.
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 used with great success for infertile human couples and involves a single sperm being injected into an egg through a thin glass pipette to
create an
embryo which is then
transferred to a surrogate female.
Typically, scientists harvest eggs and sperm to
create embryos in the lab, and then
transfer them into a female.
Some scientists, such as Kevin Eggan at Harvard, were disappointed that NIH didn't open the door to the use of
embryos created for research purposes — including through somatic cell nuclear
transfer (cloning) and parthenogenesis (from an unfertilized egg).
Stem cell researchers call them «a major step in the right direction,» although some were disappointed that NIH didn't open the door to the use of
embryos created for research purposes — including through somatic cell nuclear
transfer (cloning) and parthenogenesis (from an unfertilized egg).
Donated fresh oocytes traditionally have been used immediately,
creating embryos for
transfer into the uterus, with extra
embryos being cryopreserved for later use.
A nucleus extracted from such cells could be
transferred to an egg cell emptied of its own DNA to
create an
embryo and ultimately to bring new life into the world.
And if the cells prove to be functional enough for nuclear
transfer but not for producing offspring, they might refute one of the main arguments against therapeutic cloning: that it
creates embryos only to destroy them.
After many attempts, CC was
created by coaxing the nucleus of a cell from a calico cat into an enucleated egg; an electrical spark prompted the hybrid to divide, and the resulting
embryo was then
transferred into a surrogate mother.
Of the 29 early
embryos created by somatic - cell nuclear
transfer and implanted into various ewes by Roslin researchers, only one, Dolly, survived, suggesting that the technique currently has a high rate of embryonic and fetal loss.
Opponents said that the measure should have banned somatic cell nuclear
transfer; it criminalized only the «implantation» of an
embryo into a woman to
create a human clone.
But the favored reprogramming technique, somatic cell nuclear
transfer (SCNT), otherwise known as research cloning, is fraught with ethical pitfalls as well as technical difficulties because it entails
creating a human
embryo by inserting an adult cell nucleus into an ooctye.
The same technique — injecting pluripotent stem cells into early
embryos — failed with other combinations: The scientists couldn't
create rat - pig chimeras, and although they produced human - cow chimeric
embryos, they did not
transfer them into cows to develop into fetuses.
Finally, he opened the door to funding research involving stem cell lines
created by producing human
embryos by somatic cell nuclear
transfer or other means specifically for research in which they are killed.
The legislation would allow scientists to
create embryos for purposes of harvesting the stem cells by
transferring human DNA into animal eggs that have had most of their genetic information removed.
In 2005, the CAHR report recommended that the
embryo formed by IVF should not attract legal protection until it was
transferred in utero, at which stage it should have the same legal protection as the
embryo created in vivo [18].
Rodriguez sourced these images, which are
created to monitor an
embryo's health, from a fertility clinic, then
transferred the digital files to
create photographic negatives, which she then used to produce silver gelatin prints.
