IVF produced children are "fundamentally different"?
From http://www.kumc.edu/stemcell/."Blastocysts produced by a fertilized egg (IVF) and SCNT are considered by many to be fundamentally different, and no SCNT-blastocysts should ever be implanted in a uterus. There is no conception of new life via SCNT."
A blastocyst is the term used to describe a stage of developement of an embryo. I find it interesting that they classify both IVF embryos and SCNT embryos as being "fundamentally different". IVF is in vitro fertilization, a common procedure used to assist couples unable to get pregnant through plain ol' sex. In IVF, eggs are removed from the women's ovaries and mixed in a petri dish with sperm donated from the man. Thus fertilization takes place in a lab dish. The fertilized eggs are then placed inside the women's uterus where at least a percentage of them will latch onto the uterine wall and grow like any other traditional pregnancy. In most cases, there are embryos that are leftover from the in vtiro process and placed in cryoprotection (frozen) for the couple to use at a later date.
I personally know children who came to exist through IVF, and I do not believe their parents would consider them "fundamentally different". Nor would I. I do not believe that anyone including a medical doctor or scientist could distinguish an IVF kid from a "traditionally produced" kid. If one could scan their DNA and compare them, one could not distinguish the two to know which was an IVF baby.
What they have done is try to throw the "leftover" IVF embryos into the same category with the SCNT (somatic cell nuclear transfer- the same process by which Dolly the sheep came to exist. ) embryos. If they can convince us to think that these embryos are somehow less than human, maybe we won't mind destroying either type for use in medical research.
"Many researchers hold that an embryo at the stem-cell stage does not constitute a human, and so its loss represents a small price to pay in exchange for the potential medical benefits they see in using stems cells." A more ethical way to harvest stem cells? by Peter N. Spotts. The Christian Science Monitor. Oct. 17, 2005
What exactly makes an embryo derived from IVF or SCNT "fundamentally different" such that it would "not constitute a human"? Both have all the DNA needed to become a fully developed human being. They are both growing inside human eggs. Human materials are used to create both types of embryos. This argument simply cannot hold water when it pertains to the IVF embryos. We have too many children successfully produced from this method. All those little frozen embryos out there being stored in fertility clinics are not fundamentally different in any way. They are humans in the earliest stages of developement, just like you and I once were.
But what about the SCNT embryos? Why do they say, "There is no conception of new life via SCNT." Dolly the sheep was new life- a seperate, individual sheep from her genetic donor. Like IVF embryos, the DNA of SCNT embryos is fully human. The materials used to create them are human. They are developing inside a human egg. According to Dr. Chang of Washington University, St. Louis, they metabolize energy and require nutrients to develop and grow just like any other embryo growing in a woman's uterus or in a lab. Many researchers believe that at the current level of science, they could not continue the developement of the SCNT embryos past the stem cell phase. In other words, they would die anyway so we might as well get the stem cells from them. I believe this shows the true colors of this whole intiative. There is new life via SCNT, but it cannot continue to live past a certain developemental stage. Therefore, they want to use SCNT technology to create a life, knowing full well it cannot develop past a certain point, and then use it as a "supplier" of stem cells. This is exploitation, plain and simple, ugly and loathesome.
"It's not quite fully human", they say. So it's okay to exploit it for our purposes, especially for the "good of the general public". Hmmm.....haven't we heard that argument somewhere before? Isn't that what Hitler said about the jews and anyone else non-aryan? Of course, his intent was to outright eradicate all non-aryans. And since they were going to be murdered anyway, Hitler's minions did all sorts of horrible experiments on jews and others. And wasn't this also the same argument used to enslave blacks for hundreds of years? After all, they do look different than whites, even a bit more primitive some have said. They must be somewhat less than fully human. Or maybe they are in an earlier stage of developement or evolution. So we can exploit them for the greater good of society. Those plantations must be kept running at all costs. Our economy, the good of the people, depends on them.
Medical science will eventually catch up to the point where researchers will be able to develop the life of these SCNT produced embryos beyond the stem cell phase and eventually through to full reproductive cloning, as was the case with Dolly the sheep. And what then? Will it still be ok to destroy these embryos, even for "the greater good"? Are they really "fundamentally different" given that their DNA sequence is complete and fundamentally human and that they are living beings with a metabolism. Even if they are "fundamentally different", does that really justify their destruction, even for a good cause. Does simply being a human in the earliest stages of developement make one "fundamentally different" enough so as to be non-human? At what stage of developement will a human being be recognized as a human being? Who will decide when humanity begins? Everyone reading this was once an embryo. Some of you might even have been IVF embryos. Are we, as a people, so desperate to have cures and treatments for various diseases and conditions that we are willing to sell our souls and sear our consciences to obtain them?
