SUN-LB50 Increased In Vivo Pulsatile LH Secretion and Hypothalamic Kisspeptin, NKB, and Dynorphin RNA Levels in a PCOS-Like Mouse Model

Polycystic ovary syndrome (PCOS) is a reproductive disorder in women characterized by hyperandrogenemia, anovulation, cystic ovaries, and LH hyper-pulsatility, but the mechanisms causing the pathophysiology remain incompletely understood. We recently reported a novel mouse model that recapitulates the majority of PCOS phenotypes in adulthood. Females given constant, long-term letrozole to reduce aromatase activity demonstrate PCOS-like...
