Anti-Müllerian hormone in disorders of sex determination and differentiation.
Masculinisation of internal and external genitalia during foetal development depends on the existence of two discrete testicular hormones: Leydig cell-secreted testosterone drives the differentiation of the Wolffian ducts, the urogenital sinus and the external genitalia, whereas Sertoli cell-produced anti-Müllerian hormone (AMH) provokes the regression of Müllerian ducts. The absence of AMH act...
متن کاملAnti-Müllerian hormone produces endocrine sex reversal of fetal ovaries.
We have previously reported that anti-Müllerian hormone (AMH), also known as Müllerian-inhibiting substance, the testicular glycoprotein involved in regression of the Müllerian ducts of the male fetus, induces the formation of seminiferous cord-like structures in fetal ovaries exposed to it in organ culture. We have now investigated the effect of bovine AMH, purified to homogeneity, on ovarian ...
متن کاملAnti-Müllerian Hormone and Its Clinical Use in Pediatrics with Special Emphasis on Disorders of Sex Development
Using measurements of circulating anti-Müllerian hormone (AMH) in diagnosing and managing reproductive disorders in pediatric patients requires thorough knowledge on normative values according to age and gender. We provide age- and sex-specific reference ranges for the Immunotech assay and conversion factors for the DSL and Generation II assays. With this tool in hand, the pediatrician can use ...
متن کاملAnti - Müllerian hormone in sheep follicles ( 1 )
The purpose of this work was to study anti-MOllerian hormone (AMH) secretion during ovarian development in sheep before and after birth. We used avidinbiotin immunocytochemistry and a monoclonal antibody specific for ruminant AMH. Only granulosa cells have an immunoreactivity ; this immunoreactivity was influenced by animal age and by the degree of follicular development. In the fetus, no immun...
متن کاملAbnormal sex-duct development in female moles: the role of anti-Müllerian hormone and testosterone.
We have performed a morphological, hormonal and molecular study of the development of the sex ducts in the mole Talpa occidentalis. Females develop bilateral ovotestes with a functional ovarian portion and disgenic testicular tissue. The Müllerian ducts develop normally in females and their regression is very fast in males, suggesting a powerful action of the anti-Müllerian hormone in the mole....
