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...
INTRODUCTION Fertility is referred to the capability for having offspring and can be evaluated by fertility rate. Women's fertility is strictly dependent on individual's age. The fertility peak occurs in the early 20s, and it starts to decline in the third and fourth decades of life (falling sharply after age 35). AIM The aim of this work is to review the available data concerning fertility i...
Anti-Müllerian hormone (AMH) is a glycoprotein produced by the granulosa cells of preantral and small antral follicles. AMH concentrations reflect ovarian physiology with high precision, thus serving as a more sensitive marker of the ovarian re-serve than chronological age. This hormone plays a role in the pathogenesis of menstrual disorders and fertility in both obesity and polycystic ovary sy...
The clinical use of anti-Müllerian hormone (AMH) has increased exponentially due to its unique relationship with the ovarian reserve and ability to predict ovarian response, facilitate pretreatment counselling and individualize treatment strategies to minimize the risk of ovarian hyperstimulation syndrome. There is now a rapidly increasing literature examining additional possibilities for AMH, ...
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...
Objective We compared the expression levels of Müllerian inhibiting substance (MIS)/anti-Müllerian hormone type II receptor (AMHRII) in uterine myoma and adenomyosis to evaluate the possibility of using MIS/anti-Müllerian hormone (AMH) as a biological regulator or therapeutic agent in patients with uterine leiomyoma and adenomyosis. Methods We studied normal uterine myometrium, leiomyoma, end...
Anti-Müllerian hormone (AMH) is a member of the TGF-β superfamily secreted by the gonads of both sexes. This hormone is primarily known for its role in the regression of the Müllerian ducts in male fetuses. In females, AMH is expressed in granulosa cells of developing follicles. Like other members of the TGF-β superfamily, AMH transduces its signal through two transmembrane serine/threonine kin...
The levels and intracellular localization of wild-type transforming growth factor β superfamily (TGFβ-SF) receptors are tightly regulated by endocytic trafficking, shedding and degradation. In contrast, a main regulatory mechanism of mutation-bearing receptors involves their intracellular retention. Anti-Müllerian hormone receptor II (AMHRII, also known as AMHR2) is the type-II receptor for ant...
