This document discusses the use of frozen embryos for stem cell research. It notes that there are over 400,000 frozen embryos currently in storage that some couples no longer need or want to pay to store. These could be donated to science for research purposes, which 66% of couples would prefer rather than having the embryos discarded. However, only 44% of fertility clinics offer this as an option. The document also outlines some disadvantages of using embryonic stem cells for research, such as the risk of tumor growth, but states that more research could help address these issues.

9. Problem of stem cell
• This concern can be compromised quite easily with the use
of frozen embryos. Currently there are 400,000 frozen
embryos being stored across the nation and this number
continues to rise every day.
• These embryos are extras that were created for couples
that are incapable of creating their own, but do not wish to
have another child.
• The couple then has to decide what they want to do with
these extra embryos; they have four choices:
donate the embryos to other couples, discard the embryos,
donate them to science, or keep them in storage for a fee.

10. • Most couples do not wish to give their embryos to other
couples because they don't want others to be raising their
children or they don't want their children to have unknown
siblings that they may encounter someday.
• Some would prefer to keep their embryos in storage but do
not wish to pay the fee that is required to do so, resulting in
discarded embryos.
• In a study done by the journal, Fertility and Sterility, cited
in Tara Parker-Pope's "Deciding the Fate of Frozen
Embryos", it was said that 66% of fertility patients that did
not wish to have any more children would have liked to
donate their embryos to research.

11. • The problem with this is that only 44% of the fertility
clinics involved in this study had this option, forcing them
to choose one of the others
• These embryos have already been created and can either
be destroyed or used for research, destroying them would
simply be a waste of resources.
• Some argue that stem cell research in the far future can
lead to knowledge on how to clone humans.
• This is another ethical issue related to "playing God" or
"messing with human life" as we would be creating humans
in a very unnatural way.

12. • Another disadvantage to using embryonic stem cells is the
fact that we do not currently have a complete
understanding of them.
• Embryonic stem cells and induced pluripotent stem cells
can sometimes divide uncontrollably, forming tumors and
growths made of unwanted tissues.
• The researches said, "Experiments at treating Parkinson's
disease in animals gave a slight benefit, but also killed 20%
of the animals with brain tumors caused by the embryonic
stem cells”.
• This is a serious risk but with more research scientists can
get a better understanding about these cells and likely
reduce this statistic.
