We have known for many years that estrogen is more than the female hormone. It is essential in the male gonads, and in both sexes, estrogen has functions in the skeleton and central nervous system, on behavior, and in the

This study demonstrates that ethinylestradiol (EE2), a priority estrogenic contaminant in water, can be rapidly and selectively removed from aqueous solutions using industrial-grade polyamide 612 (PA612) particles as adsorbents. Isothermal studies showed that nonporous low surface area (20 m(2) g(-1)) PA612 particles

17alpha-Ethinylestradiol (EE) is widely used as the estrogenic component of oral contraceptives (OC). In vitro and in vivo metabolism studies indicate that EE is extensively metabolised, primarily via intestinal sulfation and hepatic oxidation, glucuronidation and sulfation.
