Absence of anti-Müllerian hormone (AMH) and M2A immunoreactivities in Sertoli cell-only syndrome and maturation arrest with and without AZF microdeletions.
BACKGROUND Some genes identified in the AZF locus are expressed only in germinal cells; others are ubiquitous. AZF microdeletions seem to occur at the earliest stages of ontogenetic development, and one might therefore assume that Sertoli cells preserve some immature characteristics and that their immunophenotype may be modified by the existence of a molecular defect. MATERIALS AND METHODS Tw...
متن کاملAZF and DAZ gene copy-specific deletion analysis in maturation arrest and Sertoli cell-only syndrome.
Deletions of the AZFc region in Yq11.2, which include the DAZ gene family, are responsible for most cases of male infertility and were associated with severe oligozoospermia and also with a variable testicular pathology. To uncover the functional contribution of DAZ to human spermatogenesis, a DAZ gene copy-specific deletion analysis was previously established and showed that DAZ1/DAZ2 deletion...
متن کاملP-85: Effect of Metformin on Anti-Mullerian Hormone (AMH) Level in Women with Infertility and Polycystic Ovary Syndrome
Background Women with PCOS have increased AMH levels due to accumulated preantral and small antral in follicles. Ovulation improvement following decrease in levels of AMH could accure in these patients. The purpose of this study was to evaluate the effect of metformin on anti-Mullerian hormone levels in women with polycystic ovary syndrome and infertility MaterialsAndMethods This randomized cli...
متن کاملO-30: Evaluation of Anti-Mullerian Hormone (AMH) Cut-Off Levels in Serum and Follicular Fluid in Patients with and without Endocrinological Risk Factor in ART
Background: Assessment of AMH cut-off levels in serum and in follicle fluid (FF) for patients with (group 2, n=34) and without (group1, n= 96) endocrinological risk factors, such as ovarian hyperstimulation syndrome (OHSS) and polycystic ovary syndrome (PCOS), is clinically useful in optimising the treatment protocol. Materials and Methods: AMH was analysed in serum and FF of 130 infertile pati...
متن کاملEffect of anti-Mullerian hormone on Sertoli and Leydig cell functions in fetal and immature rats.
Anti-Mullerian hormone (AMH) is mainly involved in the regression of Mullerian ducts in male fetuses, but it may have other functions linked to gonadal development. The present study examines the effect of AMH on steroidogenesis by Sertoli and Leydig cells in fetal and immature rats during the period where AMH is physiologically produced in the testis. The basal aromatase activity of Sertoli ce...
