      Objective: To evaluate the ovarian function during early infancy in daughters of women with polycystic ovary syndrome (PCOS) treated with metformin throughout pregnancy (PCOSdþM), as a means to reduce androgen and insulin ...
    • Increased Anti-Müllerian Hormone Serum Concentrations in Prepubertal Daughters of Women with Polycystic ... 
      Sir Petermann, Lidia; Codner Dujovne, Ethel; Maliqueo Yevilao, Manuel; Echiburú López, Bárbara; Hitchsfeld, Catalina; Crisosto King, Nicolás; Pérez Bravo, Francisco; Recabarren, Sergio E.; Cassorla Goluboff, Fernando (Oxford Press, 2006-10)
      CONTEXT: Anti-Müllerian hormone (AMH) is produced by the granulosa cells and reflects follicular development. Adult women with polycystic ovary syndrome (PCOS) have increased levels of AMH associated with an excessive ...
