RESUMO
Embryo cryopreservation does not induce clear-cut anomalies at detectable rates, but several mechanisms exist for nonlethal damage during the freeze-thaw process, and the risk of moderate or delayed consequences has not been extensively investigated. In a long-term study including senescence, we compared cryopreserved and control mice for several quantitative traits. Significant differences were seen in morphophysiological and behavioral features, some of them appearing in elderly subjects. Thus, apart from its immediate toxicity, embryo cryopreservation, without being severely detrimental, may have delayed effects. These results, consistent with other findings, question the neutrality of artificial reproductive technologies and draw attention to the preimplantation stages in developmental toxicology.
