Q1. The diagram shows one way that stem cells can be produced from human embryos. Sue Medaris/University of Wisconsin-Madison (a) Stem cells can be used to treat a condition such as paralysis. Explain why. stem cells can differntiate to become any type of body cell so they could be used to replace the damaged nerve cells‚ (2) (b) During pregnancy‚ an umbilical cord and a placenta join the embryo to the mother. At birth the umbilical cord is cut. Stem cells can be obtained from

We discuss various ethical issues surrounding ARTs‚ including family relationships‚ informed choice‚ gender issues‚ embryo status and the commercialization of reproduction‚ as well as legal and policy issues. We examine the empirical evidence of the effectiveness of ARTs and suggest ways to approach ARTs in practice. What is Assistive Reproductive Technology? Assisted

cells” from human embryos for use of developing cures in health issues today. Many people debate that Stem Cell Research is equal to that of abortion because it involves an unborn human embryo. They believe this is unethical and should be stopped. What most people that make this argument do not understand is that most of these embryos have already been frozen in laboratories for future use of implantation in parents that are having difficulty in conceiving. Many of these embryos do not survive the

Stillbirth Causes Factors Linked to Late Pregnancy Loss * placental abruption Giving birth to a stillborn baby is every pregnant woman’s worst nightmare. When it does happen‚ it’s natural to want to understand why. Unfortunately‚ answers are rarely to be found -- more than 70% of stillbirths are never explained. Doctors theorize that the majority of stillbirths probably have something to do with the placenta not functioning correctly‚ and they have some other specific theories on what causes

When do Humans become Human? A Utilitarian Approach to Abortion The topic of abortion is possibly one of the more controversial topics in the bioethical world today. The major disputes regarding abortion occur over when‚ if at all‚ a foetus is considered a human being. Conversely‚ there is equal dispute over when exactly one could consider a foetus non-human‚ and whether or not that affects the morality of abortion as a whole. If we approach the topic of abortion through a utilitarian lens‚ the

stem cells? Human embryonic stem cells come from an embryo that develops from an egg. These eggs were originally collected for reproductive purposes. The eggs are fertilized in vitro‚ and the embryo is donated for research. The donation only happens after the eggs are no longer needed. The donor is informed of the intended use‚ and consent has been given. These stem cells are found when the embryo is between three and five days old. The embryo‚ at this point in development‚ is called a blastocyst

CRISPR is a revolutionary technique that edits genes‚ enabling humans to select desirable genetic traits. Although this idea of editing genes of human embryos may sound advantageous‚ editing genes can prove to be dangerous and can leads to dire consequences. Practicing CRISPR on human embryos can also violates the fundamental idea of civil rights. By implementing CRISPR and eliminating genes that we found unfavorable‚ we are essentially eliminating the diversity of the human gene pools and human

are donated from clinics"(Daley 3). However‚ the majority of embryos are never used therefore‚ they are frozen. If the donor agrees to donate doesn’t it‚ support the benefits associated with stem research which gives reason to put aside the moral issues mentioned? A frozen embryo might continue to be frozen in a clinic until it can no longer be preserved and it will be discarded; is that really the better choice then to donate the embryo to research that could save millions of lives?

as eugenics and embryo selection will facilitate this process. However‚ one can reason that disposing of the rejected live human embryos‚ discouraging the sexual fertilization between certain groups of people‚ and regarding people with certain physical and mental traits as being the inferior are unethical. Primarily‚ one can argue that simply “flushing the other embryos down the drain” is the waste of potential human life. Discarding unwanted embryos is the direct result from embryo selection: when
