Estradiol benzoate is the synthetic benzoate ester of estradiol, a steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. This agent exhibits mild anabolic and metabolic properties, and increases blood coagulability. Although estradiol benzoate is not approved by the FDA for use in humans in the United States, it is approved for veterinary use as a subdermal implant both alone (CELERIN®) and in combination with the anabolic steroid trenbolone acetate (SYNOVEX® Plus).

Estradiol-3-sulfate (E2SO4) infused intracerebroventricularly (icv) significantly increased plasma adrenocorticotropic hormone (ACTH) and cortisol concentrations. All minipumps in the treated fetuses were filled with E2SO4 in the vehicle (water) and minipumps in the control fetuses were filled with vehicle only. These minipumps deliver a constant infusion of 5 μL/h; the concentration of E2SO4 in infusates was therefore 8.33 μg/μL. It was concluded, that E2SO4 had complex actions on the fetal brain, which might involve deconjugation by steroid sulfatase. But that the net result of direct E2SO4 icv infusion was more complex than could be accounted for by infusion of E2 alone.
