Molecular analysis of bovine follicular cyst disease pathogenesis has revealed that ovarian cysts exhibit partial disrupted steroid receptor patterns related to follicle-stimulating hormone receptor (FSHR), progesterone receptor (PGR), LH/choriogonadotropin receptor (LHCGR) and estrogen receptor (ESR) [1,16,17]. This evidence concerns the gene PGR and Follicular Cyst.
