ABSTRACT
Asynchronous blastocyst transfer, supposed to equalize the developmental stage of native and alien embryos during the organogenic period, was used as a tool in a teratological investigation.
A spurious protection by the transfer as such was shown to depend on a persisting asynchrony between native and alien foetuses. The initial difference of 24 h was not nullified, but decreased to 8 h. This difference allowed transferred foetuses to pass the period of maximum sensitivity before salicylate treatment.
