Published in Reproductive BioMedicine Online, the study showed how abnormalities in five-day old human blastocysts can be identified by the rate at which they have developed, meaning the researchers could establish risk of genetic abnormality
without a biopsy.
Those in the business of promoting or conducting fertility treatments have little motivation to ensure that donors fully understand the physical and emotional stresses of fertility treatment, the absence of data regarding long-term health impacts, or the probability and repercussions of having an undiagnosed genetic abnormality
. The financial and other interests of donor agencies and physicians involved render it unlikely that this information is routinely disclosed to and understood by potential donors, or recipients, during the informed consent process.
Here, testing is confined to women at risk of an offspring with an identified genetic abnormality
