Abstract
Realizing the potential of Embryo transfer (ET) for rapid, cheap and widespread
dissemination of genetic material, the risk of transmission disease through the
embryos must be considered. The aim of this paper is to evaluate theses risks at
each step of production, storage and transfer. The pathogen agent may potentially
originate from the donor male (semen) or the donor female (oocytes, embryos) and
finally from the environmental conditions. As the differences between in vivo and
in vitro derived embryos have been well described, evaluation of the potential
risks should be assessed separately for in vivo and in vitro produced embryos.
Even if this paper insist on the diseases or diseases agents that are more questionable,
it clearly appears that ET remains the more safety way to transfer gene, provided
prevention measures are properly handled (use of donor that are specific pathogen
free, washing of embryos, additional treatment...) and furthermore it can be easily
seen as the best way to prevent some disease transmissions (TSEs, leukosis,
foot-and-mouth disease...).
Key words: embryo transfer / disease transmission / sanitary control / in vitro fertilization
