The first and possibly most poignant argument in favor of keeping cloning legal is as a way to help couples who cannot conceive a child naturally. There are many couples is the world in which one or both of the individuals is unable to naturally donate their genes for the purpose of procreation. However, through cloning, these people would have a chance to give birth to a child that is genetically related to them. This, to many people, is more desirable than raising an adopted child or using sperm and eggs from an unrelated donor. This way the parents will be relieved and assured that their genes will be passed on to future generations. It was announced in late 1997 by Dr. Richard Seed that he would open a fertility clinic in either the United States or Mexico by 1999 to help infertile couple using cloning.

Another case for cloning is presented by Steven Vere who says, "Exceptional people are valuable in many ways, both culturally and financially" (Vere 2). Vere, like many others, argues that the cloning would allow the "re-birth" of exceptional or important historical figures of science, politics, and entertainment. For example, cloning brilliant mathematicians and physicists such as Sir Isaac Newton or Albert Einstein, to name only two, could have great benefits for science. While the clones of these people would not be like the originals in every way it is believed that their capacity for intelligence would be as great if not greater. Studies have shown that identical twins who are raised apart often share similar personalities and intelligence, even though they possessed entirely different experience and background (Vere 3). Similarly, cloning people with outstanding sports or artistic skills such as basketball star Michael Jordan or painter/sculptor Michelangelo would be applauded by sports fans and art lovers everywhere.

Finally, there are those that say cloning is selfish and some just have funny feelings about it. There are thousands of children waiting to be adopted in countries all over the world. To use cloning to have a child would be a selfish act of neglect of those children. It is true that there are children that could be adopted, but to say that cloning is selfish in this respect is like saying that anyone who has their own child is selfish because they too could adopt rather than having their own child (Hume 4). As for the funny feelings or what is often called the "Yuk Factor", it is hardly a reason to ban anything. People can feel funny about anything under the sun without justification for outlawing it.

Another possible medical advance that could be developed through cloning research is the diagnosis and even curing of genetic diseases such as diabetes. Before an artificially fertilized embryo is implanted a cell from the embryo could be cloned and analyzed for genes that cause diseases. This way an embryo with the highest chance of good health and survival could be selected for implantation. This could also lead to diagnosis and prevention of, or even the c
