Resumo

Assisted Reproduction Techniques (ART) –Ovarian stimulation, intrauterine insemination (IUI) or In Vitro Fertilization (IVF) / Intracytoplasmic injection of sperm (ISCI)– have made possible the birth of hundreds of children, and many of them are entering adulthood. In the early 90’s began a pediatric alert for defects and anomalies presented by these children, a higher proportion than those born naturally. Their health is unquestionably worse since 2002. Techniques used are extremely aggressive; the loss of embryos before implantation, spontaneous abortions and perinatal mortality is very high. Essential animal experimentation have not been carried out: and tests with fertile animals have shown that the offspring generated in vitro presented serious alterations. However, damages observed were simply ascribed almost entirely to the advanced age of women using these techniques, and sterility to genetic alterations of the sperm, increasing by environmental contamination. Extensive direct human experimentation has been carried out, but without observing the minimum requirements of human experimentation; ignoring the role of the techniques themselves, and how they cause defects in a number of children thus generated, or what they might transmit to future generations. This is not a question of risk / benefit regarding a health problem. The ART are not interventions to solve a physical or physiological vital problem. The proportionality between the satisfaction of the desire for maternity / paternity and risks to the child’s health should be a primary criterion, although not the only one.
