This product is mainly metabolized in the liver, which is decomposed into estradiol, and partially binds to sex hormone binding globulin (SHBG). The unconjugated free part binds to the target tissue and estrogen receptor, which produces estrogenic effect through transcription and protein synthesis.
In the liver or kidney, estrogen binds to glucuronic acid or sulfuric acid and becomes a water-soluble salt which is quickly discharged from the kidney.
