The Müllerian ducts (or paramesonephric ducts) are paired ducts of the embryo which run down the lateral sides of the urogenital ridge and terminate at the mullerian eminence in the primitive urogenital sinus. In the female, it will develop to form the fallopian tubes, uterus, and the upper portion of the vagina. It is tissue of mesodermal origin.

Development

Müllerian duct develops in females and degenerates in males.

Regulation of development

The development of the Müllerian ducts is controlled by the presence or absence of "AMH", or Anti-müllerian hormone (also known as "MIF" for "Müllerian inhibiting factor", or "MIH" for "Müllerian inhibiting hormone").

Eponym

They are named after Johannes Peter Müller, a physiologist who described these ducts in his text "Bildungsgeschichte der Genitalien" in 1830.
