Inactivation of contraceptive steroid hormones by human intestinal clostridia.
Bokkenheuser, V D, Winter, J, Cohen, B I, O'Rourke, S, Mosbach, E H
Steroid hormones reduced in ring-A are devoid of hormonal activity. In metabolic experiments we found that human fecal flora reduced the delta 4-3-keto structure of natural progestins to 3...
