“In settings where reasonable statistics have been gathered merely 4.2% of embryos created in Assisted Reproductive Technology (ART) ever result in a live birth” 
There is a double or even fourfold increase in perinatal deaths among children conceived in vitro as compared to children conceived naturally. Meta-analysis of fifteen independent scientific studies conducted by American scientists indicates that the mortality rate among children conceived in vitro is twice as high as among children conceived naturally. 
Pregnancies resulting from the implantation of in vitro conceived embryos are associated with a high risk of stillbirth.
This is the finding of a Danish study by Dr. Kirsten Wisborg of the Neonatology Department and Neonatal Intensive Care Unit of the University Hospital in Aarhus. Wisborg analyzed more than twenty thousand cases of pregnancy occurring as a result of in vitro technology in the years 1989-2006. He found that the risk of stillbirth among children conceived in vitro is four times higher than among children conceived naturally. 
A marked (double or even fourfold) increase in the incidence of birth defects among children conceived in vitro.
An Australian study of 4000 children born between 1993 and 1997 showed that 4.2% of children conceived naturally suffered birth defects, as opposed to 9% of children conceived in vitro. It has been shown also that the percentage of children burdened with more than one birth defect in the control group is 0.5%, as opposed to 1.6% of children conceived in vitro. 
Researchers concerned with the risk of neuro-orthopedic defects in children conceived in vitro have identified the existence of these defects in 0.89% of children conceived in vitro as compared to 0.32% of children conceived naturally. 
In September 2009, Alexander Baranov, Vice-President of the Russian Academy of Medical Sciences, speaking in the State Duma, appealed to the authorities not to refund in vitro treatments. Citing global statistics, he said that “the use of the in vitro method increases the risk of children being born with defects. In Russia 75% of test-tube babies are born disabled. If we spend money on in vitro, then we should right away allocate money for the care of the invalids who will be born through this method. (...) The World Health Organization does not recommend using the in vitro method. If we know what the side effects of using this method are, we should make them known. This method is also harmful to the mother’s health.” 
Vets are breeding people! Members of the “Anti-in-vitro” Committee have discovered that sixty-five centers performing in vitro fertilization procedures on people include in their staff a large number of veterinarians.
According to the committee representatives, the in vitro clinics do not even try to hide this. Outlets engaged in the artificial insemination of animals simply advertize in vitro services for people on their websites. According to the committee it is rare that a physician performs in vitro fertilization. “Anti-in-vitro” activists have sent a letter of protest to the Minister of Health, Ewa Kopacz. They demand that she take a position on this matter and explain whether such practices are in accordance with the binding procedures in Poland. The committee representatives claim that the centers employing veterinary embryologists are breaking the law. Vets are not authorized to “treat people.” According to the President of the Association, Jacek Kotula, “people who decide on the in vitro fertilization method are treated like cattle.”
