 However, for females who originally do not produce AMH proteins during foetal development, the Müllerian Duct eventually becomes the uterus and fallopian Tubes as normal.With the AMH gene mutation (PMDS Type 1), the AMH is either not produced, produced in deficient amounts, defective, secreted at the wrong critical period for male differentiation or the Müllerian ducts manifested a resistance to AMH.AMHR2 contains the instructions for generating the receptors that AMH binds to.
