Another reason that human cloning might prove to be less of a problem then expected is due to the fact that it will probably be a very inefficient way to create a life. Since cloning involves many more steps, it will always be riskier and less likely to result in a live birth than in vitro fertilization (IVF) and embryo transfer. For example, it took researchers 275 attempts to create Dolly the sheep clone and standard IVF only has a success rate of 20 percent. So, even if cloning methods improve, they will still be a very costly and ineffective method. This in turn brings up the question of why anyone would want to go through the trouble of cloning.
Unmistakably, there are going to be many reasons why people might go to the trouble of cloning and so it is interesting to note how they might accomplish this and the ethical problems that it might raise. For example, a couple might want to replace a child who has died in pregnancy, childbirth, or at a very young age. Supposing the couple was to take this path, they would probably want to clone to reproduce the lost child. However, if they realized that cloning would create an entirely different person (a delayed identical twin), then they would be very unlikely to persist in following this path.
There is always the possibility that the couple might persist even after acknowledging the genetic facts. When considering this possibility, it is evident that a couple so persistent would most likely not be hindered by ethical or legal factors. If one of our concerns and fears relates to they"re being an abundance of couples with this psychology, then everyone has more to worry about then cloning.
Another possibility that night bring up ethical concerns is the case in which a person wants a clone to have acceptable parts in case he/she needs an organ transplant later in life. This disturbing possibility would be very unlikely to occur because the clone produced would still be a human being and would have all the rights that a human being deserves.
