Panayiotis Michael Zavos (Greek: Παναγιώτης Ζαβός, or Panos Zavos, Πάνος Ζαβός) is a Greek Cypriot biologist from Cyprus. He is also an American citizen who currently lives in Lexington, Kentucky.


Dr. Panayiotis Zavos received his B.S. in Biology-Chemistry in 1970, his M.S. in Biology-Physiology in 1972 and Education Specialist in Science (Ed.S.) in 1976 from Emporia State University in Emporia, Kansas. He earned his Ph.D. in Reproductive Physiology, Biochemistry and Statistics in 1978 from the University of Minnesota in the Twin Cities, Minnesota. He received many awards among those the Distinguished Alumnus Award and the Graduate Teaching Award from Emporia State University and the Student Leadership Award from the University of Minnesota. He was recently awarded the Paul Harris Fellow Award[1], given to "an individual who contributes $1,000 or in whose name that amount is contributed."

Dr. Zavos has a long career as a reproductive specialist and he has devoted more than 25 years to academia and research. He claims himself to be the chief scientist in the development of several new and innovative technologies in the animal and human reproductive areas with worldwide implications. He has authored or coauthored more than 400 peer-reviewed publications, along with a number of solicited reviews, book chapters and popular press releases. He has presented more than 300 abstracts and other presentations at a large number of national, international and professional scientific meetings all over the world. Dr. Zavos' studies and findings have been reported in the local, national and international press. He served as an ad hoc reviewer for the NIH and other scientific groups.

Dr. Zavos is currently serving as a Member of the International Advisory Committee of the Middle East Fertility Society, and is a past Board Member of the China Academy of Science. He was awarded the first ever Honorary Professorship by the Chinese Academy of Science awarded to an American Professor by Chinese Scientists. He is also currently on the Board of Scientific and Policy Advisors for the American Council on Science and Health. He has given plenary lectures nationally and internationally at a large number of Scientific Societies meetings, has been and continues to be a visiting scientist for a number of international collaborations and exchanges.

Dr. Zavos has numerous scientific collaborations nationally and internationally and his publications have appeared in fifteen languages. He is a member of the American Society for Reproductive Medicine (ASRM), the American Society of Andrology (ASA), the European Society for Human Reproduction and Embryology (ESHRE), the Middle East Fertility Society (MEFS), the Japanese Fertility Society, the International Society of Cryobiology Sigma XI, Gamma Sigma Delta and a number of other Scientific and Professional Societies. He has served on a large number of committees for the International Society of Cryobiology, ASRM, MEFS, ESHRE and others.

Dr. Zavos also claims himself, and many others throughout the World, to be strong authority in the areas of male reproductive medicine, gamete physiology, male infertility, Andrology and other forms of ART (Assisted reproductive technology) procedures including the development of in-vitro round spermatid manipulations (ROSI procedures).

Dr. Zavos is also founder of ZDL Inc. The company serves for the people having fertility problems. Its main areas are gender selection, semen shipping, semen evaluation, home semen analysis, and others.


Panayiotis Michael Zavos is frequently considered as one who made contributions to the areas of human cloning and stem cell research. His publications have appeared in many peer-reviewed journals.

2001 -Professor Zavos, Severino Antinori, and Dr. Avi Ben-Abraham announce they are fully prepared to perform therapeutic human cloning.[1]

2002 -Zavos declared the year 2002 as "the year of human clones".[2]

2003 - On 20 May 2003, he announced the creation of a cloned human embryo.[3]

2004 -On 17 January 2004, from London, he announced [2] the creation and transfer of a cloned embryo, according to news reports.[4][5] During the announcement, Zavos presented the first evidence of the creation and transfer of a human cloned embryo for reproductive purposes. Even though no pregnancy was established, human reproduction via SCNT is possible and applicable in the future for patients with severe male or female infertility that have no other alternative options for procreating their own offspring.[6]

On 04 February 2004, it emerged that the attempt had not worked and the woman did not become pregnant. A spokeswoman for the doctor said: "Prof Zavos and his team are dedicated and will continue their efforts in producing more cloned human embryos for reproductive purposes".[7]

2009 -In April 2009, he claimed to have cloned 14 human embryos and transferred 11 of those to wombs.[8]


In his first two announcements, he provided no satisfactory evidence. Other scientists doubt(ed) his claimed accomplishments.

In 2002, Spyros Simitis, the brother of Costas Simitis, characterised Zavos's claims as "scientific barbarism". He expressed his opinion that if human cloning were to become reality, it would mean the "end of human freedom and evolution". He also referred to the possible use of cloning by governments for controlling and shaping society according to the government's will.[6][9][10]

Arthur Caplan, a bioethicist at the University of Pennsylvania, also testified before Congress; he said, "I think he is the most dangerous of the current fringe proponents of cloning, because he knows more, stretches the facts, and seems to be wallowing in a mix of publicity and fund-raising that rests on a foundation of hype."

Position on cloning ethics

Zavos claims that the Biblical injunction is "thou shall not kill" rather than "though shall not clone", and that the Bible does not explain or specify how humans should reproduce. He argues that any form of assisted reproduction (such as in vitro fertilization, or "IVF") is equally unnatural, but such methods are widely and successfully used today. According to Zavos, cloning can help a small percentage of childless couples to have biological children of their own "if they have exhausted all other means of assisted reproduction". Thus, cloning would further his belief that "all humans should have the right to have a child, the gift of life". He adds that all people have the right not to be cloned if cloning is against their ethics.
