Re: I didn't mean Zavoslibfemme ( 10/10/2003, 01:39:13 )PANAYIOTIS MICHAEL ZAVOS is a Kentucky biologist working in the human fertility field. His specialty is areas of male reproductive physiology, gamete physiology, male infertility, Andrology and other ART procedures including the development of in-vitro round spermatid manipulations (ROSI procedures.He wrote in the Sunday Herald: "INFERTILITY is reaching epidemic proportions throughout the developing world. Current developments in Assisted Reproductive Technologies (ART) mean there are numerous ways to treat specific causes of infertility. However, in cases where there are no gametes (sperm or eggs), the only alternatives offered to patients are sperm or oocyte (the immature female cell that divides to form an egg) donation. Many patients, how ever, do not want to use sperm or eggs from another person. Reproductive cloning can therefore play a very real part in the treatment of severe male or female infertility in couples that wish to have a biological child of their own. Since our announcement in January that we intend to use reproductive cloning as a means to help infertile couples, we have received nothing but opposition from those in the animal cloning field. Because of the limited knowledge of these procedures in the scientific community, we have organised, hosted and attended meetings to discuss and debate the issues of human reproductive cloning. These have involved scientists from all over the world. How ever, the 'animal cloners' feel they have exhausted all possible technologies and have come to the conclusion that the tech nology is not safe to use in humans, and would like the world to believe this notion. Let's examine the facts.Firstly, the poor cloning success rates noted by these animal cloners are mainly due to experiments that were poorly designed, poorly executed, and poorly understood and interpreted. They were mostly done in non-sterile and uncontrolled conditions. Also, when the animals died, the cause of death was unclear. Ian Wilmut from Edinburgh's Roslin Institute and Rudolph Jaenisch from the Massa chusetts Institute of Technology (MIT) in Boston have stated repeatedly that the application of animal cloning to humans is extremely dangerous, not because of ethical and social implications, but because of its potential for failure. They say possible consequences include a very high incidence of developmental abnormalities in the human clones, large offspring syndrome (LOS), placental malfunctions, and, in newborn babies, respiratory distress and circulatory problems -- common causes of death. They also stated that the rate of success as a technique of assisted reproduction is very low, at less than 3%. In an article in Time Magazine, Wilmut and Jaenisch state: 'Animal cloning is inefficient and is likely to remain so for the foreseeable future.' On the contrary, a number of studies have already shown high rates of development, in some cases matching or exceeding developmental rates seen in human IVF today. If history is any indication, one can expect that further refinements will improve efficiency rates. Scientists have been reporting success rates of 32% in goats and 80% in cows since 1998, as opposed to the poor 3% success rate Wilmut obtained when cloning Dolly in 1996. Why is Dr Wilmut incapable of reviewing and grasping those facts that appear in scientific literature?..."
