Fallatet al. (1997) were the only authors that foundsignificantly lower fertilization rates in PCOS patients compared to controls. Pabuccu et al. (2009) showedthat in PCOS patients the FR increased with higher FF AMH levels but did notcorrelate with serum AMH levels. Kaya etal. (2010) on the other hand, demonstrated a progressiveincrease in FR with higher serum AMH concentrations. The gene discussed is AMH; the disease is polycystic ovary syndrome.
