Anti-AMH (mature region) polyclonal antibody. Anti-müllerian hormone (AMH) has gained widespread interest as an indicator of ovarian function and fertility. Serum levels serve as a biomarker for the relative size of a woman's ovarian reserve and have clinical importance in predicting the success of in vitro fertilization (IVF). AMH can also be used as a surrogate diagnostic marker of polycystic ovary syndrome in cases when ultrasonographic examination is not possible.
