Most (> 70%) and perhaps all of the conjugates of testosterone generated by the mud snail are fatty acid esters (Gooding and LeBlanc 2001).
We showed previously that the predominant testosterone biotransformation process in the mud snail is the conversion of testosterone to testosterone--fatty acid esters (Gooding and LeBlanc 2001).
Indeed, we demonstrated previously that exogenously provided testosterone is not readily eliminated by the mud snail.
