When mulleer receptors are blocked or knocked out in mice within the paramesonephric duct mesenchyme, AMH-induced paramesonephric duct regression is lost. Anomalies that develop within the paramesonephric duct system continue to puzzle and fascinate obstetricians and gynecologists.
When this happens the individuals develop structures that are derived from the paramesonephric duct, and also structures that are derived from the mesonephric duct. Tail end of human embryo, from eight and a half to nine weeks old.
