AMH and cartilage-hair hypoplasia: In line with the possible role of AMH in CHH, the AMH receptor (AMHR2) has been found expressed in GnRH neurons of human three- and nine-week-old fetuses (at this embryonal stage, GnRH neurons are found in the nasal region at the beginning of the migratory pathway), and in the adult human hypothalamus of a man and a woman, post-mortem [12].
