You didn’t ask me for my own reply. I was replying to your reply to someone else.
Your reply has nothing to do with the point of my post, which was that, considering sheer numbers, it’s very plausible that more embryos have been made and killed in petri dishes in recent years than aborted, yet I am not seeing a huge effort to call a halt to these fertilization practices or punish the people involved in them. Why is that? If you truly consider embryos people, you better get on the ball about this! It also stands as an example that the scientific community at large doesn’t view embryos as living beings with rights.
BTW, I posted the article from wikipedia, which had some great references if anyone wants to go on there and check them out, in case anyone wasn’t up to speed about what I’m referring to.

In vitro fertilization is something people need to understand better before they choose the technology. Most people can’t afford the procedure because of the labor and technicians required. My cousin actually had this done when she became pregnant her first time. She conceived naturally shortly after the twins were born. Sheri then donated the embryos to science. Want to guess the reason for her conception problems? She told me the contraceptives she had used when she was younger, caused much of the problems she had later in life. Shutting down a human bodies natural system WILL cause problems. People like mak need to learn the truth before they think they know the answer to any problem.
Now comes the MAJOR problem. With millions of dollars spent in funding the research and the human life wasted, want to guess how many lives have been saved with Embryonic Stem Cell Research? Look around the internet and find one person. In the entire world you will find NOT ONE! The reason is because the embryos reproduction of random body parts cannot be shut off. An embryo has to be everything in the body and shutting of the genes isn’t possible. Dr.'s claim they might be able to someday, yet after two decades it has yet to happen, even once.
Adult Stem Cells are taken from the diseased patient and treated with their own cells. They will not reject the tissue. In fact something like 73 [http://www.stemcellresearch.org/facts/treatments.htm] diseases are fully curable with ASC.

Why Embryonic Stem Cells Are Obsolete by Dr. Bernadine Healy
I ask that you understand a source, rather than copy the stuff you find with google.

I’m curious about your stance on in vitro fertilization (fertilizing multiple eggs outside the body and injecting one or a few embryos after fertilization has occurred in vitro):
Embryo culture
Typically, embryos are cultured until having reached the 6�??�?�¢??8 cell stage three days after retrieval. In many Canadian, American and Australian programmes[citation needed], however, embryos are placed into an extended culture system with a transfer done at the blastocyst stage at around five days after retrieval, especially if many good-quality embryos are still available on day 3. Blastocyst stage transfers have been shown to result in higher pregnancy rates.[4] In Europe, transfers after 2 days are common.
Culture of embryos can either be performed in an artificial culture medium or in an autologous endometrial coculture (on top of a layer of cells from the woman’s own uterine lining). With artificial culture medium, there can either be the same culture medium throughout the period, or a sequential system can be used, in which the embryo is sequentially placed in different media. For example, when culturing to the blastocyst stage, one medium may be used for culture to day 3, and a second medium is used for culture thereafter.[5] Single or sequential medium are equally effective for the culture of human embryos to the blastocyst stage.[6] Artificial embryo culture media basically contain glucose, pyruvate, and energy-providing components, but addition of amino acids, nucleotides, vitamins, and cholesterol improve the performance of embryonic growth and development.[7] Methods to permit dynamic embryo culture with fluid flow and embryo movement are also available.[8] A new method in development uses the uterus as an incubator and the naturally occurring intrauterine fluids as culture medium by encapsulating the embryos in permeable intrauterine vessel.[9]
[edit] Embryo selection
Laboratories have developed grading methods to judge oocyte and embryo quality. In order to optimise pregnancy rates, there is significant evidence that a morphological scoring system is the best strategy for the selection of embryos.[10] However, presence of soluble HLA-G might be considered as a second parameter if a choice has to be made between embryos of morphologically equal quality.[10] Also, two-pronuclear zygotes (2PN) transitioning through 1PN or 3PN states tend to develop into poorer-quality embryos than those that constantly remain 2PN.[11]
More advanced methods of embryo profiling may also be performed in order to optimise embryo selection, as further described in the “expansions”-section below.
[edit] Embryo transfer
Main article: Embryo transfer
Embryos are failed by the embryologist based on the amount of cells, evenness of growth and degree of fragmentation. The number to be transferred depends on the number available, the age of the woman and other health and diagnostic factors. In countries such as Canada, the UK, Australia and New Zealand, a maximum of two embryos are transferred except in unusual circumstances. In the UK and according to HFEA regulations, a woman over 40 may have up to three embryos transferred, whereas in the USA, younger women may have many embryos transferred based on individual fertility diagnosis. Most clinics and country regulatory bodies seek to minimise the risk of pregnancies carrying multiples. As it is not uncommon for more implantations to take than desired, the next step faced by the expectant mother is that of selective abortion. The embryos judged to be the “best” are transferred to the patient’s uterus through a thin, plastic catheter, which goes through her vagina and cervix. Several embryos may be passed into the uterus to improve chances of implantation and pregnancy.
I’m surprised more people aren’t bombing those clinics. Aside from the case of too many embryos taking, can you imagine how many embryos just go straight into the trash?
“Alternatives to donating unused embryos are destroying them (or having them implanted at a time where pregnancy is very unlikely), keeping them frozen indefinitely, or donating them for use in research (with results in their unviability). Individual moral views on disposing leftover embryos may depend on personal views on the beginning of human personhood and definition and/or value of potential future persons and on the value that is given to fundamental research questions. Some people believe donation of leftover embryos for research is a good alternative to discarding the embryos when patients receive proper, honest and clear information about the research project, the procedures and the scientific values).”[/quote]
