stem cell research is: either the embryo is a human being or it’s not a human being‚ a person’s belief can help alter their decision on being for or against the research‚ cloning could be the answer to saving a life‚ and the potential the embryonic research can have will make a big impact on the world. To say that an embryo is or is not a human depends on the person and the concept they have on when a life is actually started. Many say that it starts at the embryo‚ where others debate that it starts

embryonic stem cell research as it possesses very big ethical questions. The reason why ethics are involved is because human life is being destroyed and another life is being saved or bettered from the medicine which will be produced by killing an embryo which can potentially save a human

clones be discriminated against of would they be equals. The subject of cloning brings up many questions. Scientists have experimented with cloning in the past‚ and they created Dolly the sheep. With Dolly the sheep‚ scientists used the technique of “embryo splitting” and created a perfect clone of a sheep. Since Dolly the sheep was created there have be regulations preventing anymore research which might lead to a clone being produced. With stem cell research many advances in medical field occur every

Many are saying that scientists should not be experimenting with human life. Although an embryo is destroyed in the process of retrieving the cells‚ the research could lead to outcomes that could save many people’s lives. If the embryos are frozen and never touched again‚ then what is the point? They could be used for important medical purposes. Another concern for some people are that this cell research could

Pre-Implantation Genetic Diagnosis & how did it begin? A. Pre-Implantation Genetic Diagnosis (or PGD) is a procedure used with in-vitro fertilization and screens embryos for genetic disorders. 1. In PGD‚ a single cell from a 3-day old embryo is removed‚ fertilized in vitro‚ and then analyzed for genetic abnormalities. 2. Only the embryos that are free from the specified genetic mutation are implanted into the woman ’s uterus for conception. B. The concept of PGD is a relatively new phenomenon.

OI treatment synthetically provides FSH and LH if the OI is caused by a direct problem with the ovary then OI can not be used as treatment. | 1.

Once fertilization has occurred‚ the resulting embryos develop for 3 to 5 days before being placed in your uterus. * Intracytoplasmic sperm injection (ICSI): One of your partner’s sperm is placed inside your egg with a microscopic needle‚ rather than many sperm positioned close to the outside of the egg‚ as in IVF‚ in a dish in a lab. Once fertilization occurs‚ the resulting embryo is placed in your uterus. * Gamete intrafallopian transfer (GIFT): Your eggs
