* '''anogenital distance''' - (AGD) A clinical measure of a parameter sexually dimorphic for genital development. This distance, from the posterior aspect of the scrotum to the anal verge, has been used as a marker for endocrine disruption in animal studies and may be shorter in infant males with genital anomalies. Recently been shown that infertile men possessed significantly shorter mean AGD. | * '''anogenital distance''' - (AGD) A clinical measure of a parameter sexually dimorphic for genital development.

* '''anorchia''' - (embryonic testicular regression, vanishing testis syndrome) Clinical term for the absence of testes in a 46,XY individual with a male phenotype. Rare abnormality with an incidence of about 1 in 20,000 male births, and occurs more frequently with cryptorchidism (1 in 177 cases). | * '''{{anorchia}}''' - (embryonic testicular regression, vanishing testis syndrome) Clinical term for the absence of testes in a 46,XY individual with a male phenotype.

* '''{{Anti-Mullerian Hormone}}''' ({{AMH}}, Müllerian Inhibiting Substance, MIS, Müllerian Inhibiting Factor, MIF) A secreted glycoprotein factor (transforming growth factor-beta, [[Developmental Signals - TGF-beta|TGF-beta]] superfamily) that regulates gonadal and genital tract development. In the male embryo, the Sertoli cell secrete AMH and inhibit paramesonephric (Mullerian) duct development. In postnatal males, AMH increases during the first month, reaching peak level at 6 months of age, and then slowly declines during childhood falling to low levels in puberty. In reproductive age women, AMH is produced in the ovary by the granulosa cells surrounding preantral and small antral follicles and serum levels may reflect the remaining follicle cohort and decrease with age. {{AMH}} | [[Developmental Signals - TGF-beta|TGF-beta]] | [https://www.omim.org/entry/600957 OMIM - AMH] | * '''{{Anti-Mullerian Hormone}}''' ({{AMH}}, Müllerian Inhibiting Substance, MIS, Müllerian Inhibiting Factor, MIF) A secreted glycoprotein factor (transforming growth factor-beta, [[Developmental Signals - TGF-beta|TGF-beta]] superfamily) that regulates gonadal and genital tract development.
