Expression of FSH/FSHR-induced genes including Cyp11a1, Cyp19a1, Lhcgr, Gata4, Npr2, Jaml, Galnt6, Znf750, and Dusp9 as well as expression of LH/LHCGR-induced genes including Pgr, Runx2, Egfr, Kiss1, Ptgs2, Adamts1, Wnt16, and Mageb16 are dependent on ERβ-signaling. These genes play a crucial role in the preovulatory maturation of ovarian follicles.
