A. F. Braga, Amanda S. Setti, Fabio F. Pasqualotto, Rita de Cássia S. Figueira, Edson Borges Jr. 1 INTRODUCTION Anti-Müllerian Hormone (AMH) The Anti-Müllerian Hormone AMH Glycoprotein TGF-β superfamily Growth and differentiation Short arm of chromosome 19 2 INTRODUCTION AMH and Sexual Differentiation 1940 - Role in male sexual differentiation (Alfred Jost) Males Females Sertoli cells Absence of AMH Regression of the Müllerian duct Müllerian duct differentiate Male reproductive tract Female reproductive tract 3 INTRODUCTION Ovarian AMH production Expressed in granulosa cells from the pre-antral and antral follicles Follicular fluid and circulation Birth Puberty 21 years of age 6% a year Menopause 4 INTRODUCTION AMH function Negative, restraining influence on initial recruitment Inhibition of cycle recruitment by lowering follicle sensitivity to FSH Transition from primordial into growing follicles is enhanced in the absence of AMH, resulting in the early exhaustion of the primordial follicle pool 5 INTRODUCTION AMH and Assisted Reproduction Oocyte yield Predictive of POR to COS Predictive of HR to COS Cycle cancellation rate Mature oocytes Obtained embryos AMH in assisted reproduction 6 INTRODUCTION AMH and oocyte quality AMH serum levels Oocyte quality Low levels (<1.66 ng/ml) High levels (>4.52 ng/ml) Poor oocyte morphology 7 OBJECTIVE To identify a possible correlation between serum AMH concentrations and (i) oocyte quality, (ii) embryo developmental competence and (iii) implantation potential 8 MATERIALS AND METHODS ICSI 408 patients January 2011 August 2013 4488 oocytes Blood samples obtained on cycle day 3 AMH -
