Vitro Fertilization - 342 words
Human in vitro fertilization is selection of embryos for the transfer to the uterus. The eggs are surgically removed from a woman's ovaries and placed in a carefully prepared broth called human tubal fluid. Six hours later, the husband's sperm cells are added. The evidence of fertilization was detected approximately 16 hours later. Later on, the scientists select four embryos that are actively dividing and carefully inserts them into the woman's uterus through her cervix. In another 10 days, a laboratory pregnancy test will tell her if the embryo has attached to her uterine wall. The average rate of achieving pregnancy being 35 percent. For fertilization of a human egg to occur, whether it b ...

Biology Research Paper: In Vitro Fertilization. - 1,959 words
In Vitro Fertilization (IVF), is the procedure whereby human babies are conceived, not in the womb but in a test tube or a Petri dish. This procedure has become one of the greatest developments in the world of medical technology. In Vitro Fertilization has given infertile couples the chance to conceive and bear a child from a full term of pregnancy. Without this procedure, their infertility would render them childless. There are many aspects of the IVF program that have been both praised and criticized. The legal, ethical and social repercussions of the IVF program have created great debate and controversy. This essay will demonstrate the procedures used in the IVF program and set out the ar ...

The Real Possibilities Of Cloning - 1,215 words
On February 22, 1999 news was announced that Dolly the lamb was the first successful animal cloned. Unlike the other cloning experiments done over the past 15 years, this was the first successful clone made with an adult cell. The cell was used to activate and program the egg from which Dolly grew. Past clones involved using the cell from a fertilized embryo in the early stages of development. As news of Ian Willmut's cloned lamb got out across the globe, many people feared what they thought could possibly never come true. With the technology to clone identical animals, can humans be cloned too? Since then topic of discussion throughout the scientific world has centered on the cloning of hum ...

As mentioned in Silberner's article, President Clinton said on this: "we must ratify the ethical consensus of the scientific and religious communities, and ban the cloning of human being"(2). While government is trying to draw the line, single individuals keep focusing their efforts in clone human beings. For example, "Seed is a physicist by education who developed a no-longer-used technique for human embryo transfer" (Silberner 1). His statements at a conference show his interest on human cloning: "we are going to have almost as much knowledge and almost as much power as God," (Silberner 2). He seems to be ...

Author: Aldous Huxley was born in 1894, and died in 1963. He first went to Eton, and then to Oxford. He was a brilliant man, and became a succesful writer of short stories in the twenties and thirties. Besides short stories he also wrote essays and novels, like 'Brave New World'. The first novels he wrote were comments on the young generation, with no goal whatsoever, that lived after WW I. Before he became the writer as we know him, he worked as a journalist and a critic of drama. In his books, especially the later ones, he sometimes presents himself as a teacher or a philosopher, to literate us as readers. Next to novels, essays and short stories he also wrote poems, biographies, plays, po ...

Cloning And The Usa - 775 words
Cloning and the United States Government On February 24, 1997 Roslin Institute in Edinburgh, Scotland announced that scientists had cloned an adult mammal for the first time. These researchers removed a nucleus from a mammary gland of a sheep and implanted the nucleus into a sheep's egg with the egg's nucleus already removed. This embryo was then inserted into a surrogate sheep's uterus. This procedure is called somatic cell nuclear transfer cloning. This process could have a great impact in medical and agricultural applications. There are many different experimental procedures for cloning. Blastomere separation is the equivalent of chemically induced identical twins. A two- to eight-cell em ...

Is It Right To Clone Humans - 941 words
After reading an essay entitled Is it right to clone a human?, I felt like I should give some information along with a more realistic view on the topic. This essay, written by Charlie Cho, is about the new technology of cloning and gives a lot of misconceptions as reasons to ban its research and future use forever. The essay makes many clear points as to why we should ban cloning. Cho states that we would be unable to decide whom these people belong to and if we use them for organ donation, what will we do with them? Do we just kill the cloned humans? He also brings up the possibility that a new form of racism for cloned humans could be created or humans could be made by the millions to figh ...

Use Of Genetic Information - 1,536 words
There have been rapid and stunning advances in the knowledge of how genes affect the specific tasks of different cells in the human body. The study of this interaction is known as human genetics. When human genetics and reproductive technology are combined they allow scientists to tailor make a human through the manipulation of human genes. Advances in human genetics and the application of them through reproductive technology could negatively affect society. The manipulation of human genetics and the personal information gained from reproductive technology will cause genetic discrimination based on economics. Genetic information obtained from reproductive technology might be used by insuranc ...

Twenty years from now, as you are walking around the square in Wilkes Barre, you pass someone who looks exactly like you. They have your same brown eyes, round face, light brown hair, short stature, and even the same dimples you possess. Can you imagine the shock and even fright that may accompany such a sighting? The world was bewildered when the news that an adult mammal was produced without any eggs being fertilized with sperm. The results of Dolly surprised society and the idea that human cloning was possible created an uproar. Many people disagree with cloning for ethical reasons. Opponents want human cloning banned, saying it would only create problems. On the other hand, scientists sa ...

Assisted Reproductive Techniques - 1,100 words
IVF is the name for in-vitro fertilization, a procedure that involves retrieving eggs and sperm from the bodies of the male and female partners and placing them together in a laboratory dish for fertilization. The fertilized eggs are then transferred two to six days later into the female partner's uterus. After the fertilized eggs are set into the uterus embryo development will hopefully occur as in a normal pregnancy. IVF is actually a four stage practice that begins with ovarian stimulation and monitoring. In order to maximize the patient's chances for successful fertilization, physicians typically use ovarian stimulation medications instead of following the natural cycle which only produc ...

Usually the insemination itself causes little if any discomfort. Following the insemination procedure the woman remains lying down with her hips elevated for 45 minutes. After this it is hoped that the sperm reached the egg naturally and pregnancy will occur from it. Gamete Intrafallopian Transfer or GIFT Gamete intrafallopian transfer, or GIFT, was developed in 1984 as a variation of in-vitro fertilization. This procedure is most often recommended for couples with unexplained infertility with the female partner having at least one open fallopian tube. ...

Human Cloning - 2,269 words
Human cloning has become a hot topic for debate. As we progressed one step closer to successfully cloning and developing a human being, legislators and the general public have become more concerned about the ethical and moral implications of this procedure. The federal government has been unsuccessful in reaching an agreement as to what policy to pass and enact. Thus, any current legislation on human cloning has been developed and enforced by individual states. The state of California is one of the few states in the United States that has a policy on human cloning. Human cloning is banned in the state of California. Because current policy does not allow for any human cloning to take place, m ...

Cloning Humans Is Ethically Permissible The question whether it is ethically permissible to clone humans has been a debate in the U.S. and in other parts of the world for some time. There are some good reasons that human cloning is relevant in our society, and there are some goods reasons that we shouldn't practice human cloning. Human cloning is an unordinary practice through which many of us are unfamiliar with, but when you look at the advantages to what can be achieved from cloning, you start to realize that human cloning is acceptable if it is used in a proper manner and regulated in today's society. Cloning became a serious issue in 1997 when Ian Campbell of Scotland announced to the w ...

Multiple Births - 1,070 words
Since the 1970s, the number of triplets and higher multiple births have quadrupled due to fertility treatments, such as, in vitro fertilization and fertility drugs. According to the National Center for Health Statistics, by 1995 alone, 9.3 million American women sought help for infertility problems (Ackerman 63). With this increase in complicated multiple pregnancies, regulations need to be set in place to avoid the undesired consequences of fertility treatments. Technology has made many advances towards helping infertile couples obtain their dream of having children. Fertility clinics are using newer techniques to increase the chances of conception. One of the most popular techniques is in ...

Cloning - 1,231 words
Since the late seventies scientists have been cloning mammals using cells taken from embryos. In July 1996, medical history was made when a sheep named Dolly was cloned. The only thing that set Dolly the sheep apart from the other clones was that she was cloned from an adult sheep cell. Before Dolly was cloned, scientists thought adult cell cloning was impossible. A clone is defined as a group of genetically identical cells. The goals and purposes for cloning range from making copies of those that have deceased to better engineering the offspring in humans and animals. Cloning could also offer a means of curing diseases. Cloning has many benefits that could be used as an aid to the human rac ...

This was the day of fusion date for Dolly, which is the natural equivalent to a conception date. An interesting note is that three different sheep were involved in producing Dolly, versus the usual two or one (in-vitro fertilization). Furthermore, the Roslin scientists used three different breeds for each sheep to prove that the experiment was a success. (Kolata 3) The reporter who described Wilmut as "Dolly's laboratory father," could have very well shined a light on a modern day Frankenstein. Mary Shelley's Frankenste ...

Stacie McBain was recently diagnosed with cancer at the age of 20. Doctors told her that the treatment she would undergo will ultimately leave her infertile. In light of this devastating news was an experimental procedure that had given Stacie the chance to become a mother. Her wish was no longer in the hands of God, but in the technology discovered by a doctor. Such experimental operations have occurred across the globe for over a decade, placing fertility procedures in the eye of an ethical storm (Meyer 94). The question remains are doctors playing God ...

Frozen Embryos, Who has legal rights? Invitro is defined as, "In glass, as in a test tube"(Taber's cyclopedic dictionary,1993), hence with reference to invitro fertilization, the term "Test tube baby". The first 'test tube baby' was Louise Brown of England (Jonsen, A. R., 1996). Dr. Patrick Steptoe and Professor Robert Edwards combined an ovum from Mrs. Brown, and sperm from Mr. Brown cultured it in a petri dish, and reimplanted the now embryo into Mrs. Brown's uterus (Jonsen, A. R.,1996). The result was the same as a child born in the usual way, only the means to the end was different. The media had a field day with this, and since then, reproduction as we know it has changed. We now use th ...

Designer Babies - 2,075 words
Within the first few hours after conception a phenomenon takes place in the one-cell human embryo that has awed scientists and philosophers for more then a century. The genes of the mother, carried by the ovum, and the genes of the father, carried by the sperm pair up. At that moment, when the paring is completed, the genetic fate of the person-to-be is sealed. The sex, color of eyes and hair, the height, blood type fingerprints, shoe size- indeed all physical and chemical characteristic are irrevocably determined, or are they? The concept of being able to look in on how genes were developing and alter how they turn out would of seemed like a science fiction novel in years past, but with mod ...
