Theophyllin and puromycine, inhibitors of the enzyme phosphodiesterase and AMPc are all able to inhibit the retrogression of mullerian ducts in the female chick embryo, grafted with an embryonic testis. We can think that these results are explained by an inhibitory action of AMPc on the mechanisms responsible for the mullerian retrogression. So the chick embryo reacts similarly as do the mammalian embryo.
