Which isomer of diethylstilbestrol is more active?

Since the trans isomer is believed to be considerably more active biologically because of its structural similarity with estradiol, it appears that the observed appreciable activity of the cis-DES test solution is a consequence of the isomerization in vivo to the trans isomer.
