Brief summary: This long-term longitudinal study of 437 Danish girls shows that AMH level measured in infancy is a useful tool to predict future ovarian activity.Anti-Müllerian hormone (AMH) is produced by granulosa cells in small ovarian follicles and thus reflects the ovarian reserve of resting primordial follicles (1). High AMH concentrations are observed in women with polycystic ovarian syndrome (PCOS) (2), while low age-specific AMH could be as...
